The Best Caching Plugins for WordPress
It has been a while since Google announced that the speed at which a site loads will affect its position in search results. The same applies to mobile devices. But what should worry you most is how a slow site affects users. For example, are you aware that half of internet users believe a site should load in two seconds or less? I think that is quite fair, because when you think about it, there is nothing more annoying than watching something load. Not to mention the inconvenience a person feels when they want to buy something and the site lags.
Fortunately, there are many ways to speed up your site. One of the best options is to use a dedicated caching (cache) module. Today we will briefly look at what caching is and why it is so critical when it comes to page loading speed. I will also share with you a list of the best cache plugins on the market.
What Is a Cache?
A cache is a place in computer memory where data is stored for future use. For example, instead of fully running the process of loading a site from the database, part of the data is pulled from the cache. When a visitor browses your site, the site requests data from the database stored on the hosting. More precisely, it requests the images, JavaScript and CSS of your site so that it is turned into readable HTML files and delivered straight to the browser. Unfortunately, this process requires certain resources and takes time. However, there is no need for site users to run this process every time. Especially when it comes to the static content of your site, for example published posts that hardly anyone will edit anymore.
That is why caching your site is necessary if you want to:
- quickly provide access to site data that rarely changes
- speed up the whole site loading process
- provide a better user experience for all visitors to your site
- move up in search engine rankings thanks to better loading metrics
- save server resources and reduce the number of crashes
As you can see, there are plenty of advantages to caching your WordPress site.
The core features found in each of the plugins mentioned:
- caching for mobile users
- file size reduction and GZIP compression
- configurable cache clearing schedules
- HTTPS/SSL support
