Optimize your WordPress site with a CDN to speed up your WordPress site’s performance. Learn how implementing Content Delivery Networks can enhance page speed and, in turn, increase site performance.
A Content Delivery Network, or CDN, is an excellent solution for making your WordPress site faster. A CDN makes and keeps copies of your website files, and when someone visits your website, the CDN delivers the cached files from the server nearest to the visitor.
This leads to faster loading of your site, therefore making your site very useful to those who visit it. So in this extensive guide, let us delve into what actually a CDN is, how it works, why WordPress needs a CDN, how to select the perfect CDN provider, and finally, how to implement a CDN for WordPress.
What is a CDN?
A Content Delivery Network is a group of distributed servers that provides content and files of a website to users depending on their geographical location.
CDN is a system of servers that are placed in different data centers all around the world. When a user accesses files in your site, the CDN will deliver the required files from the nearest server to the user in the shortest time possible.
This is especially helpful for websites that have users from all over the world accessing them.
Advantages of Implementing CDN for WordPress
There are several major benefits to using a CDN with your WordPress site:There are several major benefits to using a CDN with your WordPress site:
#1. Faster Page Load Times
This is the first advantage of a CDN and is the main reason why most websites use it. By getting the file copies closer to the website visitors, it minimizes the latency and packet loss experienced. Pages have a lower load time since the distance files have to travel is shorter.
#2. Improved Site Performance
This brings us to the fact that with faster load times, your WordPress site is capable of accommodating more traffic without slowing down. This also alleviates your main servers from handling demanding loads; therefore, the CDN frees processing power for other uses.
#3. Better User Experience
The web page speed directly affects the user engagement and their satisfaction level with the web page. Users prefer to spend more time on Web sites, which are fast at loading their contents on all kinds of devices. Google also takes speeds into consideration when ranking sites.
#4. Increased Scalability
CDNs are helpful in expanding the web traffic as they help offload the work from the main web servers. You can accommodate traffic increases from higher visitor traffic without necessarily having to invest in expensive infrastructure.
#5. Enhanced Security
A CDN service helps to shield websites from various hacks, such as DDoS attacks, by ‘absorbing’ the traffic that users send to the origin server. It enhances security over your WordPress site because it offers extra layers of protection.
How to Select the Right CDN for WordPress
With so many CDN services available, here are key factors to evaluate when deciding on the best option for your WordPress site:With so many CDN services available, here are key factors to evaluate when deciding on the best option for your WordPress site:
#1. Performance Benchmarks
Perform independent CDN speed tests from key testing locations to other locations to compare with your target demographic locations.
#2. Caching Rules and Controls
This means that caching rules can be made flexible to decide which files get cached and for how long. This is because, while the cache hit ratio is increased, the goal of maximizing the benefits that can be derived from caches is achieved.
#3. Instant Cache Purges
For a CDN to be effective, it should have fast cache buster that can help to clear out the cache when new files have been uploaded. Low purge rates can create site visitor misconceptions.
#4. WordPress Integration and Optimization
Select a CDN service provider designed to optimize WordPress performance with a clear WP integration process. Auto-detection of new/updated WP files is also an added advantage.
#5. Reliability and Uptime
This means that the service has a high availability rate (99.9%), meaning that your content will always be available to the visitors on your site. Seek out multiple servers that help route traffic in cases where servers fail.
#6. Affordability
CDN cost depends on various options like features, bandwidth and so on. The most costly plans are not always the best. Focus on the features that are most likely to yield the highest return on investment towards your potential goals and your monetary allowance.
#7. Technical Support Options
Real-time customer support is essential when it comes to responding to its customers’ concerns. Other self-service tools, such as knowledge bases and communities, are also used to solve issues on their own.
