Top 8 WordPress caching plugins to boost your site speed

Posted November 20th, 2019 in Web Development. Tagged: , .

Where you once happy with the performance of your WordPress site only to find out that it is not loading as fast as it did before?
If that is the case, maybe it is time that you consider installing a WordPress caching plugin. A caching will help you speed up your site.


But first, what is caching?

Your browser is loading all the site elements the moment users visit a page on your site. Therefore, several requests are being sent to the server. Each request can affect your website’s page loading speed.

This is the principle of a dynamic website: Each time a page is shown by a new visitor and via queries, all the elements are being requested from the web server.

How can caching plugins improve a website’s loading speed?

As your WordPress site gradually grows, mostly due to the publication of new content and installing new plugins, this can cause your site to slow down. This can lead to the poor performance of your site during high spikes of traffic, especially if you are only using a low-quality web host.

A caching gets a copy of your web pages, storing them in your server as either cached database queries or static files.

Then, when a site visitor visits a page, the server provides them with a cached page rather than generating your database or re-querying. Thus, speeding your site’s response times and decreasing the server resources that are needed in serving a web page.

Moreover, the faster a website loads, the better the user experience will be.

There are a lot of caching plugins out there in the market, and in this post, we will discuss the more popular and highly recommended caching plugins.

Caching Plugins for WordPress

The fastest (and the most effective way) to speed up your site is through caching tools. Using caching plugins is one of the most effective solutions to speed up your site.

In fact, about half of your audience would want your website to load within three seconds. Therefore, it does not come off as a surprise anymore that Google gives huge emphasis on site speed in its search algorithm.

The quicker your site speed is, the better your search ranking is, and the better your organic traffic will be.
