Five Free Content Distribution Networks to Boost Your SEO

How Do CDNs Function and What Are They?

You must understand how CDNs operate before you can determine which ones are the finest. Otherwise, you won’t know your head from your tail when examining your requirements and the capabilities that the available CDNs have to offer.

A CDN functions like a local server by caching your files and delivering them to users as needed. If it seems similar to what your web server is doing, that’s because it is. However, CDNs employ a more worldwide level of presence to deliver content to you much more quickly. A web host server is also required as the foundation for your content.

CDN Edge Server

A user asking to load a page on your website constitutes a normal site load. Your web host server receives a request from their browser and determines which files must be loaded before returning them. They load in the user’s view SEO company in delhi.

However, there may be a considerable distance between the user’s location and the web server. It could have to zigzag from a local router to an ISP router to a network hub and back again before reaching a backbone, and it will have to repeat the process in reverse at the data centre where your web host keeps your files. Some pathways are brief—Google strives to make theirs brief—but others are much longer. On Monitis, you may see a graphic illustration of this.

The data must travel a great distance if your web server is in California and your user is in New York. A user in New York will have a slower loading time than a person in Nevada. A CDN can help in this situation.

Imagine if the web host server was ALWAYS “next next door” rather than having to hop between nodes all across the nation. That is how a CDN works. In hubs, nodes, and data centres around the nation and the globe, they purchase, rent, or lease server space. After that, they cache the data and inspect your website. Instead of sending back all the data when a user loads your website, it provides a framework and instructions to get the files from the CDN. These files are loaded by the CDN, which is located 10 miles from the user in an unmarked warehouse, without any reduction in transfer speed caused by multiple additional hops.

The trick is that because a CDN has thousands of these servers, there is almost always a CDN server close by, no matter where the user is in the world.

How a CDN Helps with SEO

So how can a content delivery network help your website rank better in search results? Well, measuring site load times is the easiest method. The quicker your site loads, the higher your rating will be—up to a point. Google has said that site speed is a ranking consideration.

Pagespeed developers for Google

Google is aware that there will always be some variation and that there are sometimes inevitable online slowdowns. Your SEO is unlikely to suffer from a brief DDoS. Your SEO is unlikely to be significantly improved by reducing the time it takes for your site to load by.10 seconds. Google essentially just takes into account a broad threshold. You can get the notion by imagining that anything less 2 seconds is “excellent,” anything between 2 and 5, and anything beyond 5, is “awful.” Although I can’t swear for Google’s actual gradients, it is the kind of approach you may anticipate.

There are several techniques to make your website load more quickly. Just one of them is a CDN. Your files may be compressed to become smaller and load more quickly. Web protocols often support GZip. To incorporate websites like YouTube, you may also unload bigger media items, including videos. Your picture files may be compressed using image editing tools. Additionally, you may minify your scripts and codes to get rid of extraneous characters and formatting. This is a hard suggestion, but if you routinely have human developers working on your site, maintaining formatting might be a good idea to keep things organised.

Google also offers its own suggestions. They recommend that you avoid redirects on landing pages, load scripts asynchronously, and give priority to your visible content over background material like analytics scripts. Find out more about it by reading this.

Google offers some really harsh guidelines. For instance, they advise against using plugins even though they are essential to a successful WordPress installation. It’s a toss-up, however, since well-programmed plugins load quickly and don’t impede the performance of your website.

A quicker website may also help with SEO in other ways. A significant one is bounce rate. If people attempt to access your website, wait a few seconds for it to load, and then leave, your page is loading too slowly. Your SEO will benefit in a variety of ways by decreasing your bounce rate.

Another intriguing side effect of contemporary search technologies exists. Response speed is crucial when using a voice search engine like Siri, Cortana, Alexa, or Google Now. Particularly Google will look for the top result, but if it takes too long to load, it will automatically move on to the next result to locate one that loads quickly.

So, can a CDN harm your website? Actually not at all. Most CDNs combine speed with an additional degree of protection. They improve the stability of your website and assist defend against DDoS assaults. They may sometimes have negative impacts, but generally speaking, the good will exceed the bad.

Top Seven Free CDN Services

A good CDN must thus have a vast network, which rules out any local startups. It must be dependable, with uninterrupted uptime and redundancy in the event of a single server failure. It must support the programmes, plugins, scripts, and files you need hosting, as well as genuinely speed up your website in use.

Finding a CDN that can accomplish everything in this case is not difficult. Actually, almost any CDN is adequate. Finding them for nothing is the difficult part. The finest CDNs are those like Akamai and Cloudfront, whose prices depend on the size, quantity, and number of files housed as well as the number of times those files are loaded in a particular time frame. Pricing is too unstable for me to bother keeping track of it, and although being normally pretty affordable, it is still not free. Free is the best price on a bill.

First Free Choice: Capsule

Incapsula is a business-class CDN with a wide range of features, many of which come highly recommended for big or well-known companies. They have a firewall, bot suppression, SSL, DDoS protection, uptime SLAs, bespoke security, load balancing, and an API at the highest level. But all of this is only available with their expensive subscriptions.


Although it’s hard to locate, Incapsula also offers a free plan. A short note regarding a free plan that is primarily for small blogs and includes bot mitigation, CDN access, and two-factor authentication can be found on their price website, underneath the major plans. You may either click here to join up or browse to it yourself.

There are several things that the free plan does not provide. It lacks backdoor defence, SSL support, DDoS defence, failover, and many other enterprise-level advantages. Additionally, it restricts your support to just local aid, which might be a deal-breaker if you have concerns about it.

Option #2 is free: PageCDN

PageCDN is a potent CDN that combines the power of CDNs with content optimization. You’ll be able to do the majority of the work utilising this CDN if you want to utilise it. PageCDN will handle the caching and website performance for you, so you won’t need to utilise any additional tools.

Paid and free options are available from PageCDN. This implies that, if you so desire, you may speed up your website with no cost. However, this CDN stands out from the competition because to its premium features, one of the greatest of which is the host consolidation option.

PageCDN integrates all the material and serves it via a single host, unlike other CDNs that establish subdomains for each origin. This significantly speeds up the delivery.

You may access a number of extra premium capabilities with PageCDN, including:

Image resizing, optimization, and conversion in the cloud

Simple HTTP cache optimization using immutable caching available

automatically optimising DNS

accelerated delivery over the global network of PageCDN

Automatic cache sharing using open-source libraries with other websites

modern compression that can improve compression by up to 27%

CSS and JS minification in the cloud

Plugin for WordPress – Easy Speedup

If certain resources are cached by other websites, reusing third-party cache may help webpages load more quickly.

HTTP/2 Server Push to further accelerate the webpage

So what services does the Free plan offer?

CDN provides hundreds of open source libraries including jQuery, WordPress themes and plugins

Cache sharing across several websites

Can switch to public CDN with ease

Immutable cache for open-source libraries

Great Browser and Edge cache hit ratio

Finally, PageCDN provides Easy Fonts, which acts as an excellent alternative to Google Fonts.

The only difference?

They load quicker since they’re more cachable. This implies that your PageSpeed score will increase when you utilise them too.

Free Option #3: Swarmify

Swarmify is basically a startup giving distributed loading for video material, if you don’t want to put all of your films on YouTube. I’m going to totally overlook all of those features, however, since they’re paid-only. The free aspect is really exclusively for WordPress blogs, dubbed the WordPress Acceleration Plan.

Swarmify Website

Plus the WPAP, you receive 10GB of picture delivery per month, with local geo-serving and email support. It’s not much, it doesn’t allow video or scripts, but for an image-heavy website it may be wonderful. Do be aware that if you go over your bandwidth allocation, they charge you five cents per gigabyte beyond.

Free Option #4: JSDelivr

JSDelivr, with the oh-so-trendy following r instead of er, is a CDN that is free and open source.

It’s similar to Swarmify in that it is focused on one thing only, not a general broad-spectrum CDN. In this case, that “thing” is JavaScript. You can use it to offload your scripts to an extremely fast-loading CDN. Since they don’t have to deal with bulky media and can focus on running smaller, faster scripts, it’s blazing fast. The limitation of needing to use another CDN for your media can make it less ideal, however.

Free Option #5: Google’s App Engine

Google’s App Engine is a non-traditional CDN that doesn’t do basic scripts or media; instead, it’s designed to host and run web-based applications. This means it’s ideal if you’re trying to run a web business or host a task app, but that’s a specialised use case that’s not ideal for everyone.

The primary benefit of the App Engine is twofold. First, it’s free for up to five million uses per month, with half a gig of storage space and hosting for up to ten projects. Secondly, it’s deeply integrated with all of the other Google services. If you’re used to using Google services, it’s ideal.

On top of that, it’s not just a CDN – it’s a development space. Your developers can use App Engine directly to create and test the app, not just host and run it. This can be invaluable if you don’t have your own local test environment.

Free Option #6: Cloudflare\sCloudflare Website

Cloudflare tends to approach their services from a security standpoint more than a delivery standpoint, and they filter bad traffic very aggressively. This is great for DDoS protection, but it also makes them the #1 most common CDN error I see in my time using the web. I can’t tell you how many times I’ve tried to visit a site and found just a Cloudflare error page instead.

That said, if you’re willing to give them a try, they might work out for you. Also, they’re excellent for DDoS protection, at least in the sense that they’ll protect your data. Your site might be difficult or slow to access during a DDoS, but it’s less likely to bug out and reveal data to users or collapse completely.

Free Option #7: Coral CDN

Coral CDN is an interesting experimental CDN that works not with server farms but with peer-to-peer loading. It’s a cool experiment, but I wouldn’t have recommended using it as a business, because it requires that you append a secondary domain to your own domain to load the request through their CDN. That’s one way phishing scammers fake a site, so it’s not a great look.

Also, Coral CDN hasn’t worked since 2015. I only bring it up because the idea of a peer to peer CDN is very cool and could, in a better world, be a much more powerful version of a CDN than the traditional data centre model. For now, though, you’ll have to content yourself with one of the above options.
