Use Caching to Improve your WordPress Pagespeed

Caching is very important to maintain a fast loading website.

What is caching? Why caching is important?

Caching is a way of keeping data in storage to allow retrieval without having to request the data from the original source if that data will not change frequently.

A typical caching scenario is having a cached copy of a web page. That page doesn’t change every five minutes, so caching it locally on your computer saves time and bandwidth for you to re-display it if you hit reload in your browser.

Cache is generally much faster than loading from disk or having a server generate a page from scratch. We have covered the top 8 best caching plugins. You can use any of the cache plugins mentioned in the post. For example, if you prefer mod_rewrite cache, then WP Super Cache can help you to implement caching efficiently on your WordPress website.

Reduce HTTP Requests

When you add many different services, it sends HTTP requests to various sites. If you want to improve page loading time, you need to reduce HTTP requests as little as you can. For example, many social sharing plugins send many HTTP requests to implement sharing. These can significantly slow down your website.

On another instance, Facebook Comments takes a lot of time to load because the plugin loads Facebook comment using JS and sends many HTTP requests to Facebook. This can significantly slow down your website. You can significantly improve pagespeed on WordPress by reducing HTTP requests

Use a Content Delivery Network

Using a Content Delivery Network is a good idea to distribute the load. The concept of a content delivery network is that different providers place servers at various locations around the world. When you use a CDN, the request is served from the nearest server. This results in much faster loading time.

If you are looking for a free CDN, then try Cloudflare. Cloudflare is a Content Delivery Network that also provides many useful features like DNS Manager, HTTP/2 with free SSL and more.

Remove Render Blocking Javascripts

What is render-blocking Javascript? Javascripts that are loaded in above the fold of a website is called render blocking javascript. Render blocking javascript can slow down your websites significantly.

Remove Render Blocking JS

Hence, the user experience gets much worse when users cannot load the most vital part of a website in minimal time. Often users get frustrated by slow loading time and simply closes the tab.

You should avoid and minimize the use of blocking JavaScript, especially external scripts that must be fetched before they can be executed. Scripts that are necessary to render page content can be inlined to avoid extra network requests, however the inlined content needs to be small and must execute quickly to deliver good performance. Scripts that are not critical to initial render should be made asynchronous or deferred until after the first render. Please keep in mind that for this to improve your loading time, you must also optimize CSS delivery.

Google Page Speed Insights

One good way to remove render blocking javascript is to load the javascript in the footer. Then, the user will be able to see the website in an instant, and the javascript will load later. Win-win for both developers and users! Autoptimize can help you to reduce render blocking javascripts too.

Enable Gzip Compression/Brotli Compression

Gzip compression enables a compression on your website that the browser can quickly decompress. Gzip compression can significantly change your website loading time. For example, before gzip compression a website can be around 2MB, however, after gzip compression, it becomes around 500KB. Your site can load more than 50% faster by enabling gzip compression.

Most hosting companies have gzip compression by default.

Check GZIP Compression Tool

You can check if your website is already gzip compressed or not with

Wrapping on WordPress Speed Optimization
