Improving your page load times and site speed is key if you want users to spend more time on your WordPress website, build an audience, and get them to try some of your products. Back in 2010, the Google search team announced speed would be a ranking signal for desktop searches, and as of July 2018, this was extended to mobile searches as well. While the ultimate goal was improving user experience, faster load times can boost your site ranking on the\u00a0 Search Engine Results Page(SERP).\u00a0<\/span><\/p>\n

Content Deliver Networks (CDN) have become critical in building modern web applications. Over time CDNs have also become increasingly popular and important in improving performance, reliability, and the resilience of webpages to cyber attacks.\u00a0<\/span><\/p>\n

In this article, we’ll define a CDN and let you know how WordPress CDNs work, their advantages, and how to install one on your WordPress site. We will also outline some of the best CDN solutions available and how you can leverage them to improve load times. We will also give you expert tips on how 10Web can help you speed up your WordPress site<\/a>.<\/span><\/p>\n

What is a Content Delivery Network (CDN)?<\/span><\/h2>\n

A <\/span>CDN<\/span><\/a> is a network of geographically distributed proxy servers that work together to speed up content delivery to the end users. Also known as CDN Point of Presence (CDN PoPs), these servers are located at junction points of high-speed internet fiber cables in order to be able to serve web pages at the highest speed. Having users access content based on their geo-proximity to CDN servers takes the load off the origin server and significantly reduces latency.<\/span><\/p>\n

How WordPress CDN Works<\/span><\/h2>\n

Using a CDN on your WordPress site is similar to using it on any other website. CDNs are strategically placed in front of the web server hosting your WordPress site. Through reverse proxy load balancing, they take off the load on your server by distributing traffic to cached pages across different PoPs.\u00a0 These PoPs represent different data centres that are geographically distributed around different regions of the world.\u00a0<\/span><\/p>\n

The main principle behind using a robust CDN infrastructure is geo-proximity which is often combined with caching to server data to the user by region in the most optimal time possible.<\/span><\/p>\n

Typically, CDN servers cache static resources<\/a> such as media, fonts, CSS, and JS files so that whenever a user requests these resources, they are served the cached versions. The cached resources are stored and served from a server close to users in a given region. <\/span>But it is even more powerful when webpages are served from CDN. Such mode of operation is possible if CDN supports reverse proxy. Not only just cached, but also optimized webpages can be served through a CDN, making a website super fast.<\/span><\/p>\n

For instance, when a user is accessing a Website hosted in San Francisco from Dubai UAE for the first time, all the requested static resources are requested from the main server and cached on a CDN server near them. On subsequent requests, these users are served with the cached copy from the closest Point of Presence. This reduces the distance these resources travel if the request were to be made to the host server in San Francisco again.<\/span><\/p>\n

These resources have certain expiration periods (cache expiration), and whenever they expire, the same process of retrieval and update from the main (origin) server happens again. Also, resources can be updated manually (cache flush or reset), for example, if the original content is modified.<\/span><\/p>\n

Do you need a CDN for WordPress?<\/span><\/h2>\n

If you want to improve your WordPress load times<\/a> and the user experience, then a CDN is something you should consider. However, many other reasons may influence your decision. Here are some:<\/span><\/p>\n

If your WordPress site has a global audience<\/b><\/h3>\n

Unless you’re using geolocation restrictions, also known as geoblocking, to prevent users from certain geographic locations from accessing your content, your website is likely to attract visitors from all over the world. To guarantee fast load times and a good user experience for visitors located far away from where your website is hosted, you’ll need to set up CDN Points of Presence that are closer to these users.<\/span><\/p>\n

A CDN is still a good idea even when a fairly small number of visitors is outside the primary location where your website is hosted. You can access real-time statics of your WordPress site visitors using a WordPress plugin of your choice.<\/span><\/p>\n

If your WordPress site has large media files<\/b><\/h3>\n

Big media files are one of the significant causes of slow load times on websites. Having a CDN in place will take the load off the main server where your website is hosted and instead serve these static resources from distributed CDN PoPs.\u00a0<\/span><\/p>\n

Unoptimized images are also the most common culprits of slow WordPress sites.<\/a> A CDN for images will automatically resize, compress and optimize images allowing you to deliver graphics and images seamlessly. Faster delivery of images is key to creating a good user experience, especially on mobile devices.<\/span><\/p>\n

If your WordPress site experiences traffic spikes<\/b><\/h3>\n

A sudden increase in the number of visitors to your website is good only if your website is prepared to handle such spikes. More website traffic means more conversion rates if you’re running a business. However, a sudden surge in the number of visitors can also break your website and cause a temporary outage.<\/span><\/p>\n

By distributing requests across different servers through reverse proxying, CDN servers enable your website to handle seasonal or unexpected traffic. Besides reducing the load on your central server, a CDN can <\/span>(depending on what type of content it serves)<\/span> also help mitigate a DDoS attack and protect your production server. A CDN is, therefore, a good way to guarantee uptime and eliminate single points of failure.<\/span><\/p>\n

We have discussed why you need a CDN for your WordPress site. Virtually any business can benefit from a CDN. However, some businesses can only function well if CDNs are in place.<\/span><\/p>\n

    Benefits of using a CDN on your WordPress site<\/span><\/h2>\n

    Here are some of the benefits of using a CDN on your WordPress site:<\/span><\/p>\n

    1. Performance boost<\/span><\/h3>\n

    Optimizing your WordPress load time is a great way to give users a good experience browsing your site. Happy users are likely to keep browsing your site and are more likely to try your products. On the other hand, if your page takes more than the recommended time to display content, users are likely to think that your page is broken. A good load time, ideally 0 to 4 seconds, correlates to high conversion rates, while a load time greater than that leads to higher bounce rates.<\/span><\/p>\n

    Google uses a handful of signals to measure site performance.\u00a0 Among the most recent addition to this list is the page experience signal that combines the <\/span>Core<\/span> Web Vitals (CWV)<\/span> such as the <\/span>Largest Contentful Paint<\/span><\/a>, <\/span>First Input Delay<\/span><\/a>, and <\/span>Cumulative Layout Shift<\/span><\/a>.\u00a0 By caching status resources such as images, videos, CSS, and JS close to the users\u2019 location, a CDN can help improve your core web initials scores.<\/span><\/p>\n

    Although page load time is affected by many factors, a CDN can boost performance and increase the chances of your site attaining a <\/span>90+ PageSpeed score.<\/span><\/a>\u00a0<\/span><\/p>\n\r\n
