How many times have you had the experience of website taking too long to load? When you are running a WordPress site, it will seem really fast at the beginning. But over time you will realize that your site is slowing down and is not performing as it once used to.

So what can be the possible reason for that and how you can prevent your site from slowing down to the point of irritation? Well, the solution is right here in the form of WordPress caching plugins and this article will be all about some of the popular caching plugins, its benefits, features and more that are used in WordPress sites all around the world.

But before we move onto more details on the plugins, let’s take a quick idea about what caching really means and how it works in WordPress sites.

What Do You Know about Cache? Let’s find out Briefly How It Works.

How cache works

While on a computer when you try to get quick access upon request, the cache is something that temporarily collects stored data. All these data are usually stored together in the hard disk of the computer. So when someone requests for these data, the computer presents the requested information after running several processing grids.

By storing the frequently requested information in a temporary memory, caching resolves the issue by fetching the information quicker.

How Cache Works in WordPress

This same cache mechanism can be applied for your WordPress site as well when you are required to load your site quicker improving its performance.

As a vast content management platform, WordPress requires this concept of cache to make the site load faster. Basically it just helps your WordPress site fetch the required information onto the user’s browsers after performing several other steps collecting data from the database every time a user visits the site.  

When many users use the WordPress site at the same time, it tends to slow down the processing time while they are in it. But when the caching is working, it enables the WordPress site to dodge a few steps instead of going through the complete process of page generation every time. After you have loaded a page for the very first time, your caching normally copies the page you visit. And then from the cache memory, it provides the stored version of the page to all the following users trying to visit that page.

Caching plugin is important. But Why?

We have already spoken about how a website slows down after a while of usage. Now what a caching plugin does on your website is that, it generates pages with static HTML to save it on the server. So whenever a user tries to visit your website, instead of processing the relatively heavier WordPress PHP scripts it presents the lighter HTML page. As a result the caching plugin help enhance page loading time.

Apart from boosting the speed of your website, there are other ways by which you can realize that having caching plugin in your site is more than essential. Here are some of the common impacts and importance of using a caching plugin.

  • Conversion Rates: Based on reliable stats of Kissmetrics, almost 40% of the visitors lose their patience and leave a site if the website’s loading time takes even a little longer than usual. So more people leaving your site quicker means, if you have a business website, you are losing out on more customers decreasing your conversion rates. Nowadays even a single second of delay may diminish your conversion by 7%. So keeping your website fast and moving with a caching plugin can improve the rate of your conversion in no time.
  • The impression of Website: The image of a website also gets hampered when your site frequently takes too long to load. As a normal visitor, you would want to visit a website that takes minimal loading time. Even an increment of a few seconds of page loading time can spoil the impression of your website among users. So using a good caching plugin can always save you from the negative implication of your website.
  • Search Engine Rankings: More than twice, the impact of a caching plugin related to the speed of the website. Even for a good ranking of your content in google search engine you require to keep the page speed of your site optimized as Google uses page loading speed as a determinant element of where to rank your content in the results of its search engine. So if you have a slow website, there is every chance your content will land inside the latter position of google search engine page results. But, all that can be improved by optimizing your webpage speed with a proper caching plugin.
  • Overall User Experience: When a user can roam around a website smoothly, then that user is likely to spend more time on that website. They would also tend to visit more pages of the same site more often. This decreases the bounce rates of a website that runs swiftly. As people’s attention shifts very quickly nowadays so it is really important to keep the users occupied providing them a good user experience when they visit your website. They wouldn’t even be interested to wait around even for few seconds for any page to load. So the faster the website, the better is the overall user experience they get. Not just the user-experience it also uplifts the engagement and escalates the time a users spend on that website.
