7 Highly Effective CDN-SEO Tips to Boost Your Rankings

Content Delivery Network or CDN is the modern-day messenger pigeon that races across time and distance to deliver information.
To put in simple words, CDN is a group of proxy servers that deliver content to the users within a quick time from the nearest server.
Luckily for us, CDNs cannot be shot down by enemy kingdoms and don’t die from fatigue. But their responsibility to deliver timely content is far more urgent as the wrath of online shoppers can be deadly to Ecommerce businesses.
When in the hands of innovative businesses, CDNs can be used as a potent weapon to boost overall visibility. It is a great tool to minimize the page load time, improve security, boost search engine rankings and optimize content availability. Its main goal is to keep the request-response time as low as possible so that pages load faster.
This will ensure that popular search engines like Google, Bing, and Yahoo will display links to your website content right at the top.
This way, visibility being can be easily achieved, which is SEO's primary goal. And this, in turn, will attract more traffic which will translate into direct revenue. A study by Bing shows that websites that appear on top of a search garner 42% traffic while websites that appear second and third only receive 11% and 8%.
As CDN reduces and optimizes page loading time significantly, it directly impacts the search engine results. Customers will find your page faster, spend less time purchasing your services, and hence will have a hassle-free online experience.
Let's have a quick look at seven ways in which your SEO ratings can be effectively improved using CDN.

1. Minimizes Page Loading Time

In the internet world, speed is good; speed doesn't kill. Having pages that load less than three seconds is crucial to your company's performance online. Fast page speed is a valuable asset that must be acquired for successful SEO.
Time and again, studies have shown the relevance between SEO and site speed. Google had announced once in 2010 and again in 2018 that site speed is a significant ranking factor. Amazon found that sites that took an extra 100 milliseconds to load saw a one percent drop in sales.
It’s believed that websites with loading speeds below 3s are considered good to fetch better ranks on SERP. Webmasters can check site speed on Pagespeed Insights or GTMetrix.
And CDNs play a major role in keeping this number at a minimum. As it brings the user and original server closer, data gets transmitted faster. Pages load faster. This, in turn, ensures a low bounce rate and high dwell time which directly boosts conversion rates.

2. Crunch the Images for Maximum Optimization

Content online is rarely created without visual aid. But it is far easier to click a picture than to send it. This is because images occupy a ton of space. Studies show that unoptimized images can make websites load three or four times slower than normal. This will have disastrous results on search engine rankings.
A CDN is every Ecommerce company's best bet to prevent this from happening. With their automatic image optimization capabilities, CDNs will help in reducing image size without compromising image quality.
Here’s how CDN helps deliver your images to the users without delay.
They offer diverse compression and image format options as well. This directly improves the website's performance that is sent to the user by the CDN from its cache data.

3. Provides Indication for Duplicate Content

Google and other search engines majorly frown upon duplicate content being found in multiple places. This will impact your rankings and drastically affect your accountability. With the help of CDN, you can avoid these using canonical headers and caching algorithms.
Through such canonical links, the network informs search engines that certain content is a copied version and clearly states where it can find the original version. This is usually indicated by adding an HTTPS before the link.
However, it is always advised for Ecommerce businesses to use their original domain even while operating a CDN to feature high on SERP rankings.

4. Boosts Availability of Content

A CDN enables you to store static data or commonly searched pages with unchanged information for long periods. Online users more frequently look up such pages. And these don't need to be retrieved from the central server located miles away, thus reducing page load time considerably.
A CDN works to fetch information to the users within a jiffy.
By tweaking the HTTP header, you can decide how long static data should be cached in the CDN. For example, home and product pages for most websites remain unchanged irrespective of time and location.
Other pages known as dynamic data like the checkout or delivery page, which is subject to change, can be stored in the main server. These features mainly focus on reducing page load time which in turn directly improves SEO.

5. Keeps Your Content and Website Secure

Though firewalls and antivirus are standard options for web security, CDN has become a fast-rising popular choice. By using better hardware technology, diverting traffic from the server, and quick functional scalability, CDN performs a vital function of protecting your content. And it does this pretty well.
Moreover, CDN is adept at preventing and fighting DDoS attacks that are powered by harmful malware.
Also, as CDNs act as a middleman between the user and the server, it prevents heavy traffic from bombarding the server and protecting its overall performance. But businesses must be cautious while choosing the right CDN provider to prevent future attacks by hackers.

6. Acts as a Backup Server

A CDN acts as a perfect backup for the main server as it ensures that the website always remains active. This way, customers can access it at any time or location. And companies usually operate with multiple CDNs, which further act as more backup servers.
Hence, if the main server or a CDN in one location malfunctions, user requests are redistributed automatically to other CDNs closest to the user location. This way, users never lose access to your website. This dramatically improves your chance of getting a high SERP ranking.

Another advantage of using CDN is that it can minimize the byte size of your content. This way, information gets transmitted rapidly to the user.

7. Improves Overall Site performance

All the above-listed points make sure information reaches your target audience with minimum hurdles. CDN is an easy-to-set-up and cost-effective option to hone your SEO strategy. It's one of the fastest methods to ensure maximum utilization of your website with minimum effort.
This also ensures users get faster access to your content.
Creating engaging content, SE-optimizing your website, setting up multiple backlinks, and all other efforts will go in vain if your page load time takes an eternity. This improves the overall user experience by keeping the bounce rate at a minimum.
It enables you to deal with heavy online traffic from multiple locations and time zones with ease, hence keeping your profits growing. Akamai has found that websites that have a high sales rate load 26% faster than others.
