In a world where an online presence is crucial, an HTTP flood attack poses a significant threat, overwhelming websites with an onslaught of requests that can result in digital paralysis. This article delves into the essence of HTTP flood attacks, explaining their function and why they are a menace to web servers.

What is an HTTP flood attack?

An HTTP flood attack is a form of Distributed Denial of Service (DDoS) attack specifically targeting web servers. In this malicious assault, the attacker overwhelms a web server with an enormous volume of HTTP requests, rendering it incapable of handling legitimate user requests. This tactic capitalizes on the stateless nature of the HTTP protocol, allowing for easy forging and amplification of requests. Such attacks can come from a single source or be distributed across multiple locations, making them harder to trace and block. The simplicity of executing these attacks makes them a popular tool among cybercriminals looking to disrupt online services.

HTTP flood attack

How does it work?

Step 1: Request Amplification

HTTP flood attacks exploit the stateless nature of the HTTP protocol, enabling attackers to forge a vast number of seemingly legitimate requests. These requests are often designed to consume server resources disproportionately.

Step 2: Botnet Deployment

Perpetrators commonly utilize botnets, networks of compromised computers, to amplify the scale and impact of the attack. This distributed approach makes it challenging to trace and mitigate the source of the assault.

Step 3: Targeting Specific Vulnerabilities

HTTP flood attacks may exploit vulnerabilities in web server software, operating systems, or specific applications. By pinpointing weaknesses, attackers maximize the efficacy of their assault.

Types of HTTP flood attacks

In the realm of HTTP flood attacks, adversaries deploy a variety of tactics to overwhelm web servers, each with its own distinctive approach.

  • GET Floods: GET Floods are a type of HTTP flood attack that targets the HTTP GET method used in web communication. Attackers send a massive number of GET requests to a web server, designed to look like legitimate user interactions, with the aim of overwhelming the server’s resources and capacity to respond. Imagine your website is a popular restaurant, and suddenly, an overwhelming number of customers flood in, each asking for the menu without any intention of placing an order. GET floods operate similarly, bombarding the server with a surge of requests for information, causing chaos and resource exhaustion.
  • POST Floods:  POST Floods focus on the HTTP POST method, which is used for sending data to a server. In these attacks, cybercriminals flood the server with numerous POST requests, often containing seemingly valid data submissions. This flood of requests can strain the server’s CPU and memory resources, causing delayed responses or service disruptions. Picture customers storming in and placing orders at an unprecedented rate, without any regard for the kitchen’s capacity. POST floods emulate this scenario by inundating the server with an excessive number of data-submission requests, pushing the server to its limits and potentially causing it to stumble.

Impact of HTTP flood attack

Picture your website as a bustling city during rush hour and an HTTP flood attack as an unexpected surge in traffic causing digital gridlock. This online congestion not only disrupts normal operations but also leads to inevitable downtime and service interruptions as the server contends with an overwhelming influx of requests.

  • Downtime and Service Disruption. Think of your website as a bustling city with countless residents seeking information. An HTTP flood attack is like an unexpected traffic jam, bringing the entire city to a standstill. Downtime and service disruption become inevitable as the server struggles to handle the overwhelming surge of requests.

  • Financial Loss. Just as a shop loses revenue when forced to close unexpectedly, businesses hit by an HTTP flood attack experience financial setbacks. The loss isn’t just in terms of immediate revenue; it’s also about potential future earnings as user trust takes a hit.
  • Reputational Damage. Consider the impact on a brand when its flagship store experiences a sudden closure. Similarly, successful HTTP flood attacks can tarnish a website’s reputation, eroding the hard-earned trust of users. Reputational damage extends beyond the immediate attack, affecting long-term relationships with customers.

5 Signs your website is under HTTP flood attack

Early detection of an HTTP flood attack is crucial for effective response. Here are technical indicators that may signal such an attack:

  1. Increased HTTP Request Rates: If your web server logs show a sudden and sustained increase in HTTP GET or POST requests, especially from a range of unusual IP addresses, this could indicate an attack. Monitoring tools can be configured to alert administrators to spikes that exceed baseline levels.
  2. Increased CPU and Memory Usage: HTTP flood attacks force the server to handle a massive number of requests, leading to unusual CPU and memory consumption. If your server resources are maxing out unexpectedly, this might be a sign of a flood attack.
  3. Slow or Non-Responsive Website: A significant HTTP flood attack can slow down your website or make it entirely unresponsive, as the server struggles to handle the load. If your site becomes inaccessible or experiences frequent timeouts, it may be under attack.
  4. Log Files Full of Repetitive Requests: When reviewing server logs, you may notice a large volume of similar requests, often with the same IP range, user agent, or request URL. This repetitive pattern is a hallmark of HTTP flood attacks, as attackers often send requests in bursts.
  5. Increased Bounce Rate Without Clear Cause: When legitimate users experience a slow or non-responsive website due to an attack, they are more likely to leave. If you see a sudden increase in bounce rate without an obvious reason, an HTTP flood attack may be the culprit.

Preventive measures against HTTP flood attack

Detecting an HTTP flood attack is akin to being the vigilant lifeguard at a crowded beach.

Monitoring service

Just as a lifeguard watches the ocean for irregularities, detecting HTTP flood attacks involves monitoring for abnormal spikes in web traffic. An unexpected surge signals trouble, prompting a swift response to ensure the safety of the online “beach.” With HTTP/HTTPS Monitoring service you will be able to keep track of the performance and availability of websites, web applications, and web services.

Web Application Firewalls (WAFs)

Think of WAFs as the vigilant eye of the lifeguard tower, surveying the digital sea. These firewalls analyze incoming traffic, identifying and blocking any suspicious activity, acting as a proactive defense against potential threats.

DDoS Mitigation Services

There are services specifically designed to protect against DDoS attacks, including HTTP Floods. DDoD Protection services work by diverting traffic through their networks first, filtering out the bad traffic, and only sending the good traffic to your server.

Implement Content Delivery Networks (CDNs)

CDNs distribute your content across multiple, geographically diverse servers, so it’s closer to your users. This not only speeds up content delivery but also means that traffic is spread out and not directed at a single server, making it harder for an HTTP Flood to have an impact. In addition, at ClouDNS you can build your own CDN with our GeoDNS service. With it you can be one layer protected against these malicious attacks. 

How to create your own CDN using DNS

Creating Redundancies

Have a backup plan, or in technical terms, create redundancies. If one server or network component fails under the load, others can take over. This is like having backup generators ready in case the main power supply goes out.

Conclusion

Though HTTP flood attacks present a real and present danger to web servers, the good news is that they are not insurmountable. By staying vigilant, employing a layered security approach, and embracing both reactive and proactive defense strategies, businesses can effectively dampen the impact of these attacks. Ensuring your website’s resilience in the digital ecosystem is key, allowing you to maintain seamless operations and safeguard your digital assets against such disruptive forces.

Do you want to give your users the best possible performance? The Traffic Director can help you to do that! With it, you can direct DNS queries through strategically placed nameservers, optimizing your query traffic with custom regionalization. Want to learn more? Let’s explore more details about how it functions and the benefits that it brings.

Explanation of Traffic Director 

Traffic director is a way to optimize and manage the traffic going to your domain by using geographical-based routing. Like this, your clients from Asia will get connected to your Asian servers; your European clients will connect to the closest servers they have in Europe and so on.
Traffic Director is a cloud-based implementation of Load Balancing (you can check our article on Load Balancing). It helps to improve the performance of your network. It can be incredibly useful for medium and large companies that need to deliver content to different parts of the world.

Some companies call this service traffic director, others Global Traffic Director (GTD) or GeoDNS director, but it is best known as GeoDNS, and that is why we use this term as the name of our service.

How does it perform?

Traffic Director gives you easy access to a powerful global load-balancing system by making configuration easy. All you need to do is set your own regional rules, and the Traffic Director will intelligently direct DNS queries through strategically-placed nameservers.

ClouDNS enables you to optimize your query traffic with custom regionalization, allowing you to divide traffic across six global regions:

  • Africa
  • Asia
  • Europe
  • North America
  • Oceania
  • South America

By leveraging Traffic Director, you can ensure your site visitors have a better experience. For example, through regionalized configurations, queries are redirected to the geographically closest nameservers, meaning Chicago visitors would be answered by a nameserver in the North American region rather than relying on a Asia or even overseas-based server.

Traffic Director

In addition, If you want to ensure users from France, for example, receive the best possible experience, the Traffic Director can help you achieve this. Its regionalized configurations enable you to specify that all DNS queries from the country-based region (France) should be answered by a server located in Paris. This means you can ensure users are connected to the closest, most efficient nameserver. 

DNS lookups are the first step in making any DNS request. In order to produce the best user experience, DNS traffic must be routed efficiently and with purpose. If it is not handled optimally, it can lead to poor performance and contribute to a degraded user experience. By using a Traffic Director, you can ensure users get the speedy, reliable performance they deserve.

Typical DNS vs. Anycast vs. GeoDNS

Typically, you will have few DNS servers. A visitor trying to connect will ask at random one of them for your web server’s IP address. The visitor will be lucky if the server is close and not so happy if it is far away, but he or she will get the same IP address.
If you are using just an Anycast, multiple servers will respond to the same IP. With it, the visitor will get a response from the topologically closest nameserver. The reaction is quick, but it still can take time to connect to the web server if it is far away.
Here comes the GeoDNS/Traffic Director and its advantages. By using it, a visitor will get a different IP address, depending on his/her location. It will result in fast DNS query response and consequently fast connection to the web server.

Why should you get a Traffic Director/GeoDNS?

Multiple Geolocation target options

You can efficiently target regions, countries or whole continents. You can create an exact Geolocation load balancing. Filter your visitors and direct them to the servers which are closest.

Well-placed servers
We have located our servers close to high traffic international locations.

ClouDNS network is continuously growing. We have currently 50+ Anycast DNS locations on six continents for faster DNS query resolving.

DDoS Protected DNS
DDoS attacks are becoming a common threat. For your convenience and safety, our GeoDNS plans include DDoS Protection.
DDoS attacks and how to protect ourselves

Cost Effective
Although our plans include a limited amount of queries per month, we won’t charge you extra or temporarily stop your DNS if you get additional traffic in a month or two. If this trend continues for a more extended period, we will just propose a more suitable plan for your needs.

EDNS-client/subnet support
Our service makes decisions based on the real locations of the visitors, not on those of the DNS resolver.

SEO friendly
One of the most important factors of SEO is the speed. Thanks to the Network System of servers, the DNS queries will be resolved faster, and this will help you have higher SEO ranking.

Who can benefit from using Traffic Director?

Traffic Director, with its advanced load balancing and network traffic management capabilities, can provide significant advantages for a wide range of industries and sectors. Here are some key entities and scenarios where a Traffic Director can be highly beneficial:

  • Large Enterprises and Corporations: Companies with large online operations, such as those in e-commerce, financial services, and digital media, can highly benefit from Traffic Director. It ensures that their websites and applications can handle massive traffic volumes efficiently, improving user experience and minimizing downtime during peak periods.
  • Cloud Service Providers: Providers that offer cloud computing resources and infrastructure as a service (IaaS) can use Traffic Director to manage and distribute traffic across their data centers more effectively. That way, it enhances performance and reliability and optimizes resource utilization, leading to cost efficiency.
  • Telecommunications Companies: Telecom operators can use a Traffic Director to manage the vast amounts of data passing through their networks. By efficiently routing traffic, they can enhance the quality of service for their subscribers and reduce the load on network infrastructure.
  • Online Gaming and Entertainment: In industries where customer satisfaction is closely tied to the responsiveness and stability of the service, like online gaming, Traffic Director is a game-changer. It plays a crucial role in managing sudden spikes in traffic and maintaining a seamless user experience.

Do you remember the time when we were reading the news in a printed newspaper and we were going to a video store to rent a VHS? The things have changed a lot ever since. Now you get the daily brief from an online portal and the content rental stores are all in the clouds. CDN is responsible for the global distribution of all that content. It makes it possible that all the viewers get their content in a matter of milliseconds, even if they live far away from the source.

Every media company who wants to be international relies on CDN. Youtube, Amazon, Netflix and many more can’t provide equal service in so many different locations without it. It can deliver quality 4k video without buffering (if the visitors have quality internet too), thereby enhancing the viewer’s experience. The effectiveness of CDN technology in managing and distributing digital content has become a cornerstone for media companies aiming to achieve global reach and maintain high service quality.

The Essence of CDN in Modern Media

CDN stands for Content Delivery Network, a system that delivers content all across the world. Imagine you have a media company that wants to show videos to different countries. You can’t have just your web hosting, because it will get all the traffic and it will get saturated. So much traffic that it can get down. And downtime means losses that you can’t afford. You need something to balance the load on an international level and that secures you 100% uptime so you wouldn’t have any angry customers.

This is where a CDN becomes invaluable, distributing your content through a network of servers located around the globe. This ensures that your content is served from the location nearest to the viewer, dramatically reducing latency and improving the overall viewing experience. Furthermore, CDNs are designed to handle spikes in traffic, ensuring that your media content remains available during peak times. This is particularly crucial for media companies, where even a slight delay can lead to a poor user experience and, ultimately, lost viewership or readership.

GeoDNS: Powering Next-Generation Content Delivery Networks

GeoDNS stands at the forefront of content delivery innovation, offering a streamlined alternative to traditional CDN mechanisms. By leveraging GeoDNS, media companies can build a highly responsive, globally distributed network that intelligently routes content based on the geographic location of the audience. This ensures that users receive data from the nearest server, minimizing latency and maximizing speed.

The sophistication of GeoDNS allows for dynamic content localization, enabling media to tailor experiences to specific markets with unprecedented precision. Furthermore, it facilitates efficient load balancing and traffic management across the network, enhancing overall system resilience and reliability. By adopting GeoDNS, media companies not only optimize their content delivery for speed and efficiency but also gain the flexibility to quickly adapt to changes in viewer demographics and consumption patterns.

Building a Resilient CDN Network with GeoDNS

The Strategic Advantage of GeoDNS for Media Companies

Cost and Efficiency: Creating a CDN through GeoDNS eliminates the need for expensive Anycast networks, making it an affordable solution for media organizations of all sizes. And once you start using the ClouDNS GeoDNS service, your visitors’ queries will pass through our DNS servers – each of which uses our Anycast DNS network, near your customers.

Enhanced User Experience: By serving content from geographically proximate servers, GeoDNS minimizes delays and buffering, crucial for maintaining viewer engagement and satisfaction.

Simplified Management: GeoDNS offers a straightforward way to manage global content delivery without the complexity and overhead associated with traditional CDN setups.

Furthermore, for streaming platforms, the imperative to deliver seamless, uninterrupted content is paramount. GeoDNS technology caters to this need by ensuring that video streams are efficiently routed to users from the optimal location. This not only elevates the viewing experience but also supports the platforms’ scalability as they expand into new markets.

Revolutionizing Streaming Services with GeoDNS

Expanding Global Reach While Maintaining Local Quality

One of the most significant challenges for media companies aiming to globalize their content is maintaining a consistent quality of service across diverse geographic regions. CDNs address this challenge by localizing content delivery. Regardless of the user’s location, CDNs provide a local presence that ensures content is delivered with the highest possible quality and the lowest possible latency, making global reach a realistic goal for media entities of all sizes. 

This localization strategy also allows for compliance with regional data regulations and content customization based on local preferences, further enhancing the user experience. By effectively shrinking the vast digital world into a tightly knit community of localized content delivery, CDNs enable media companies to create a universally high-quality experience that feels both global in reach and local in flavor.

CDN and SEO: A Synergistic Relationship

The benefits of CDN extend beyond just content delivery, impacting SEO rankings positively. Fast-loading pages and efficient content distribution are rewarded by search engines, highlighting the necessity of integrating CDN solutions into your digital strategy to enhance online visibility and performance. The relationship between CDN and SEO is symbiotic, with speed, reliability, and security contributing to better search rankings, while also enhancing the user experience. This synergy helps businesses to not only attract but also retain their online audience, providing a solid foundation for growth and success in the digital marketplace.

Conclusion

Leveraging GeoDNS as a CDN solution is crucial for ensuring fast, reliable, and globally scalable content delivery, enhancing both user experience and SEO performance in the competitive digital landscape. This approach not only streamlines access to digital media across diverse geographic regions but also fortifies the infrastructure against the challenges of scale and security. As the digital sphere continues to grow, the strategic implementation of GeoDNS as a CDN emerges as a pivotal asset for media companies aiming to excel in global content distribution.

Everybody uses CDN (Content Delivery Network). YouTube, Amazon, Netflix and many others are applying it on a massive world scale so you can enjoy your favorite content in a matter of milliseconds. But how does it work?

What is CDN?

CDN (Content Delivery Network) is a network of geographically distributed servers all around the world. Each of these servers is a PoP (Point of Presence). It has a cache of the data that the users in this specific location will use. CDN doesn’t substitute the web hosting; it just makes many cached data of the original data and stores it around the world for better accessibility. It works using the GeoDNS technology so the visitors of your website will be connected to the fastest/closest server, without the need to get the data from the web hosting. CDN saves a lot of time.

CDN (Content Delivery Network)

Why is it important?

A Content Delivery Network (CDN) is important because it improves the performance, scalability, and security of websites and applications. By distributing content across multiple servers located in different geographic locations, CDNs can deliver content faster and more efficiently to users. That way, it reduces latency, improves page load times, and provides a better user experience. CDNs can also handle high volumes of traffic, reducing server load and improving website scalability. Furthermore, CDNs offer security features such as DDoS protection and web application firewalls, which help protect against cyber threats. Overall, CDNs are an essential tool for modern businesses that rely on fast and efficient content delivery, global reach, and robust security.

History of CDN

Different technologies affected the birth of CDN – hierarchical caching, server farms, cache proxy deployment and improved web servers.
The first generation of CDN came around the late 90’s. People created them because of the growing use of on-demand content (audio, video, etc.). Dynamic and static content delivery. It was mostly intelligent routing and edge computer methods. The second and current generation, is cloud-based, relying on a peer-to-peer connection and it is focused on video-on-demand.

How does it work?

A Content Delivery Network (CDN) is a system of servers distributed geographically to deliver web content to users more quickly and efficiently. When a user requests a web page, the CDN provides the content from a server closer to the user’s location, reducing the time it takes to load.

The process of delivering content through a CDN typically involves the following steps:

  1. A user requests a website or a specific web page from their browser.
  2. The user’s request is received by the nearest CDN server, called an edge server, to their geographic location. The edge server is determined based on the user’s IP address, which reveals their location.
  3. If the edge server has a cached copy of the requested content, it serves it directly to the user’s browser. Caching involves storing a copy of the content on the edge server. That way, it can be delivered more quickly to users in the future.
  4. If the edge server doesn’t have a cached copy of the content, it requests it from the origin server. The origin server is the original source of the content, typically the website’s hosting server.
  5. The origin server responds by sending the requested content to the edge server.
  6. The edge server caches the received content from the origin server for future requests.
  7. Finally, the edge server provides the requested content to the user’s browser.

By distributing content across multiple servers, a CDN can reduce the load on the origin server and provide a more reliable and scalable infrastructure for delivering content to users worldwide. Additionally, since edge servers are located closer to users, the time it takes to load web pages is significantly reduced, improving the user experience.

For who is it?

Anyone can benefit from CDN. From the big companies that we mentioned before and small blog websites. The technology increases the speed of the website and can be very useful even if you have just a WordPress blog. This helps the SEO, and your website will rank a lot better in Google, and your visitors will be happier thanks to the speed boost.

Here are some examples of who can benefit the most from implementing a CDN:

  • E-commerce Platforms: E-commerce websites can experience irregular traffic patterns, especially during peak shopping seasons or promotional events. CDNs help these platforms deliver product images, videos, and web pages quickly and efficiently to customers worldwide, ensuring a seamless shopping experience and maximizing sales.
  • Media and Entertainment Companies: Streaming services, gaming platforms, and content providers rely heavily on CDNs to deliver high-quality audio and video content to users across different locations, devices and platforms. CDNs minimize buffering, reduce latency, and ensure smooth playback, enhancing the overall user experience and driving engagement.
  • Software Companies: Software companies distribute updates, patches, and installation files to users globally. CDNs accelerate the download process, reduce bandwidth consumption, and ensure reliable delivery of software updates, enabling users to access the latest releases quickly and securely.
  • News and Publishing Websites: News websites and publishing platforms require fast and reliable content delivery to keep readers informed and engaged. CDNs ensure timely delivery of articles, images, and multimedia content, even during periods of high traffic volume or breaking news events, enhancing reader satisfaction and retention.
  • Gaming Industry: Online gaming platforms depend on low-latency, high-performance networks to deliver an immersive gaming experience to players worldwide. CDNs minimize lag, reduce packet loss, and optimize server response times, providing gamers with enhanced gameplay experiences.

How to create your CDN using DNS

Benefits

CDN is able to provide numerous benefits, some of which are the following:

  • The most significant benefit is definitely the speed. It reduces the latency; everything loads way faster than before. How fast? On average 70% faster!
  • Load balancing. By using different PoPs around the world, the traffic gets well distributed, and it reduces the traffic on the original server.
  • It reduces the bandwidth consumption, so if your web host has low bandwidth, this can help you a lot.
  • It has DDoS protection. It protects you from a single point of failure, thanks to the many different PoPs.
  • It will improve the SEO of your site. Google values the speed of your website as one of the key indicators for ranking in its search engine.

Conclusion

Content Delivery Networks are getting more popular thanks to its advantages. Many people start using it for E-commerce Entertainment and blog sites. It can help you over rank your competitors on the Google pages and provide a better uptime. There is no doubt that this solution is definitely worth trying!

A CDN – Content Delivery Network is responsible for the content delivery. We all interact with CDNs on a daily basis – when we watch a video, when we read an article, when we shop online or when we use a social network site. The main reason why they exist is to reduce latency, the delay between your demand and the moment it gets on your screen. Higher latency makes us impatient and gets us angry. There are many reasons it can happen, but the main is the physical distance between your computer and the server which hosts the website. CDN makes the magic of shortening that distance, and by doing so, it improves the speed dramatically.

How does a CDN work?

To shorten the physical distance between the users and the hosting server, the CDN keeps cached versions of the original content in different geographical locations known as Points of Presence (PoP). Each of these PoPs is located strategically to serve to the users nearby.
This way, you as a user, don’t need to connect to the original source (the original server). The CDN will direct you to the closest connected server on the network, and you will get the cached version of the original version.

CDN and DNS

The benefits of a CDN

  • The most obvious is the speed. The content loads faster. According to recent tests from the Content Delivery Network KeyCDN, using a CDN reduces website latency on average by 73% compared to websites running without a CDN.
  • Handle heavy traffic. The load is handled between the PoPs and it is not so heavy for the original server.
  • It reduces the bandwidth consumption.
  • It is more secure and protects you from DDoS attacks, more Points of Presence (PoPs), fewer chances of your original server to be affected.
  • Faster loading time will improve the SEO of the website.
  • There are more benefits but these are the main. Based on these advantages, the CDNs are getting more and more popular every day. Especially for E-commerce and Entertainment.

Do I need a CDN for my website?

The internet has become quite dependent on Content Delivery Network to manage a significant amount of its content. But just because CDNs are a common practice doesn’t mean you need to consider investing in one. It’s necessary to understand how CDN DNS works and consider whether it’d be useful for your website’s needs.

CDNs are great for allowing users to access web content quickly and efficiently, even if they’re far away from where your web origin host is located. If most of your audience is nearby and can effectively access your website without much difficulty, then you may not need a CDN for your website. However, if you’re reaching a larger audience from different places, then it would be wise to invest in a CDN service. Video streaming websites, social media platforms, online journalism outlets, digital publications and eCommerce sites all benefit from having their own CDN, because it makes it easier for them to reach a larger global audience. It also allows for faster loading, which can provide more potential visitors and more potential readers. 

Overall, the advantages of a fast-loading website far outweigh the costs, and should not be ignored.

Does DNS need to be modified to support CDN?

Yes, DNS must be modified to support CDN. Domain Name System (DNS) stores, logs and allocates the IP address of your web content between web users and your web server, so any change in web content needs to be reflected in the underlying DNS record. CDN, on the other hand, adds multiple distributed server networks to reduce the amount of time needed for content to travel from the origin to the final destination. In order for these different distributed networks to work effectively, the DNS must be configured to route requests through the CDN, which allows for quicker content delivery and reduced latency. Furthermore, CDNs also use DNS to direct visitors geographically to their nearest server, which helps reduce the time it takes for the web content to load on their browser.

How to create your own CDN using DNS

To set up a CDN using your own Anycast can be very expensive. But don’t worry, there are cheaper solutions. For example, you can use GeoDNS and ordinary servers with unique IP addresses. With our GeoDNS service you can build your own CDN or Geolocation Load Balancing with highly accurate geolocation service that makes the decisions based on the real location of the visitor, not on the location of the DNS resolver.

In the time of the millennials, the businesses feel obligated to have a digital presence. How can you miss the online sells? It is almost unimaginable to be selling products without an online shop. If you are already thinking to go digital, and you have chosen the right domain name you will face the next step – deciding the right platform for your online sales. There are plenty of CMSs (content management systems) out there, but we will introduce you to the most common for e-commerce – Magento, PrestaShop, Shopify, OpenCart, WooCommerce.
First, we will start with Magento.

Magento, what is it?

Magento is an open-source CMS owned by Adobe. The platform is free* and that is why it is the popular choice of many small companies. It is also easily expandable through extensions from the Magento Marketplace. This makes it very customizable. Another benefit is the huge developers’ community behind it. The people have created a rich ecosystem around it, and they are adding new elements quite often.

Thanks to the massive interest in the platform, there are many experts in Magento and finding Magento support employees or Magento SEO experts is not hard. There is also a certification program from the brand.

Big companies also love it. Many well-known brands like Coca-Cola, Nike, and Ford, use it.
According to Alexa, from the most visited 1 million sites in the world, 19.64% use Magento (January 2018). It is the number one e-commerce platform, just in front of WooCommerce.
The Enterprise version of Magento cost 18 000 USD (Magento 2 starts at 22 000 USD). It is not free like the one for small and medium-size businesses, but it is still affordable for big brands.

Benefits of Magento

Free*

We already mention it, that there are two versions, the Community one, and the Enterprise. The first is free, and you can see the whole source code and how to install it here in GitHub.

Easy to install

You can get it from GitHub, Magento’s website or even from your web hosting provider for free. You need to follow a step-by-step process that will take you less than half an hour. If you experience any difficulties, there are plenty of YouTube tutorials on how to set it up.

Magento is full of features

It has a massive amount of pre-installed features like personalized products, purchase order management, promotion management, newsletter and more. Companies can start using it immediately, even without installing additional extensions.

SEO-friendly

E-commerce sites need all the help they can get with their SEO. They contain plenty of products and many unique pages. Magento is well-built out of the box with proper URLs, good control over the meta tags, XML sitemap and responsive design (it adapts to different screens and devices). Many extensions can help you too.

Multi-sites, a single control

Magento gives you the opportunity to install multiple sites from the same installation. Later you can set different currencies and languages for each from the same back-end administration panel. It is very convenient and saves time. If you are planning to use the multi-sites option, we recommend you to apply GeoDNS. It will increase the speed of your site, improve the SEO and it can potentially increase your sells.

Easy integration

The platform is already in a grown stage, there are plenty of developers behind it, and it is visible. It is very easy to integrate it with third-party services like – payment gateways, inventory software, shipment tracking systems and analytic software.

Magento VS Shopify – a detailed comparison

Cons of Magento

The platform is great, but it doesn’t mean it is flawless. There are few of the disadvantages that it has that are worth mentioning:

Heavy for cheap web hosting

If you want to use it with many products, it is better to rent private servers instead of a shared web hosting. You will need all the resources of the servers because there will be many operations to be made.

Time-consuming

The high customization has its price, and it is time. Yes, it gives you more options than other competitors, but it could take extra time to complete a specific task.

Enterprise version is expensive

If you want to benefit from the features of the Enterprise version, it will cost you an arm and a leg. Due to the price, just big companies with many sells or very expensive products can afford it.

Conclusion

Magento is a great way to begin with e-commerce. It covers all the necessary check boxes and even exceeds the expectations. It is the number one e-commerce platform right now, and it is totally worth it.

With the introduction of content management systems (CMS) many of us have become brave enough to start their own website. WordPress and its alternatives sure are good, but to manage them properly and to get to the first page of Google is not easy at all. Google has two main criteria to judge your SEO. The first is speed. Everything must be fast to load. The second is the mobile optimization, which means your site must look good on mobile. To manage to get that so desire first-page position, we want to share with you 5 of the most effective tips to speed up WordPress:

  1. Choose a good web hosting

As we said earlier, speed is essential. Choosing a good web hosting is not easy. Many of the web hosting companies don’t show all of the information to the public, so you need to ask extra. The most important aspects are that the servers are modern, that they use SSD, they give you enough resources for you (what percentage of the shared resources are you getting), physical location and of course the price. The web hosting might be the most significant investment so take your time.

  1. Use a barebone theme

Barebone WordPress theme might be a bit contra logical to you but bear with us for a moment. Yes, a barebone theme will be less spectacular, but again our primary concern is speed. It will load a lot faster and give you an advantage in the Google ranking. You need to be sure that the theme is mobile-friendly too. This is a very cheap update.

  1. Optimize images

And this one is entirely free! Use a compressed format like .JPG for your images and keep the resolution down. You don’t need a full 20Mpx image, especially when most of the internet traffic comes from mobile with an average 1080p display. Use 1MPx image and your pages will load fast and still provide a quality post for your visitors. For the resizing, you can use an online site or download a image resizing application on your device.

  1. Speed up WordPress using caching plugin

There are free and paid options. We recommend you WP Super Cache. This one creates static HTML files that most of your visitors will see instead of the WordPress PHP scripts. Html is lighter and easier to load.

  1. Use CDN

You can create your own CDN (content delivery network) using DNS. It will give you the chance to have many more point of presence in the world. Like this, your users from China will be redirected from the servers close to them in Asia and the ones in The US will have others close by. It will significantly reduce the time to load for your page, and you can use it with all of the previous speed up WordPress tips.

If you are interested, you can check our GeoDNS or talk to our sales team that can give you extra details.  It is relatively inexpensive, and it gives excellent results.

Conclusion

To be one step ahead of your competitors is not easy, but with good research and some tweaks, you can get far better results. Some of these speed up WordPress optimizations cost extra money, but when you see the difference in reach and positioning you will be content.

WordPress has taken the internet by storm. It is the most commonly used CMS (content management system) out there. Plenty of people are using it. With this popularity, the competition is fears. There are a lot of speed up WordPress optimizations that you can do from within, like using a barebone theme, optimizing the content or using caching plugins but all of that request that you have SEO knowledge. You can speed up your WordPress from outside by using CDN (content delivery system).

What is CDN?

CDN is a content delivery system that you can get with GeoDNS. It uses many PoPs (points of presence) around the globe, where the data of your website is cached. When a visitor wants to see your site, he or she will be redirected to the closest PoP near him or he will get the data from that server there. This saves a lot of time because his or her request won’t go to the original hosting server, but rather to the one near him. This can increase the speed significantly. For example, your website is hosted in an Asian hosting but an American is trying to visit it, then the American won’t need to get the data from Asia, he will be redirected to a server near in the United States.

The advantages of CDN

  • Boost the speed. Obviously, the shorter distance that the requests from your visitors will do, makes them load the pages faster. The speed is significant, so even with a heave WordPress there, it will still load normally.
  • SEO! You will get better ranking on Google thanks to the less loading time.
  • Load Balance. Your WordPress website is getting more popular and you are experiencing more traffic? Don’t worry, with CDN you can redirect the traffic and spread it around through the different PoPs.
  • Reduces the bandwidth. Coming from the previous point, it also helps you with the limited bandwidth that web host services provide.
  • Protection. It adds an extra level of protection against DDoS attacks by load balancing. This will lead to less downtime for your site.

Conclusion

Using a content delivery system for your WordPress site is an easy external way to speed up your site. You can combine it with internal optimization and get an excellent result. If you want to start using CDN, you can check our GeoDNS. Look at the different options and choose the best for you according to the size and traffic of your site.

What is CDN (content delivery network)

CDN is a network of servers geographically located in different areas around the world. They serve as a load balancer that redirect the traffic that goes to your website to the closest Point of Presence near you. It is like a shortcut. Now your visitors will not waste time to get to the web host service you use. They will be conveniently redirected to a cached data of your site, that is milliseconds away from them. They will open the pages fast and will have a better experience.

What is SEO?

Search engine optimization, SEO is the most important thing for your website. Better position on the search engines like Google, Yahoo and Bing will translate to more visits to your site and you know, more visits more conversions (Clicks, sales, subscriptions, etc.).

There are many factors that get accounted for the SEO, but most important few are the content, security of the site, mobile friendly, backlinks and SPEED.

To make your page load faster, you can do internal or external changes.

Internal like striping your website from unused code, keep the size down on the media content. They are harder to do and take extra time every time you need to publish new content.

Externals like choosing a good hosting, which most of the time is expensive, or use CDN for more bang for your buck. CDN is relatively cheaper than most high-level web hosting and it brings better results.

What CDN does?

It will lower the latency, making the experience of your visitors a lot more pleasant. It will improve the uptime, because now even if your web hosting is down, the visitors will still get your content through the CDN, connecting to one of the PoPs (points of presence).
As we already mentioned, you can combine it even with a cheap web hosting plan and still get excellent results. In most of the cases, it gives far better results than the expensive web hosting plans, when you compare the money.
It gives you DDoS protection. With so many PoPs, it reduces the traffic and it is very resistant.

Who can use CDN for better SEO?

Everybody! No seriously, there are no restrictions. Many Media companies and Online sellers are using it but you can see that even bloggers choose to boost their SEO with CDN. It is a very easy method and it shows result fast. If you are not sure yet, you can try our GeoDNS service for free for 30 days. See with your own eyes, the effect on the speed and that decide if it is right for you.

Conclusion

SEO is difficult to master. It is full of factors that you need to consider, but speed is a key one.
CDN is an easy way to boost your SEO. It can massively increase the loading speed of your site and your visitors will definitely love the change.
