To reduce this unnecessary burden off the site, you need an efficient WordPress caching plugin. Today, we will talk about why and what you need to know about the top caching plugins in WordPress.

Why do you need caching plugins?

When your site reaches a certain height, it starts to lose speed due to excessive loads. Too many plugins on your website jumble up the internal mechanism of your WordPress site. As a result, even a fresh WordPress installation would produce much-underrated performance. That’s why you need a WordPress caching plugin. Note that, there are a few things to notice about your site today.

How loading time impacts in WordPress

Google’s own statistic states that a single second of site speed increases/reduces the traffic by 60%+. As we are continuously upgrading our technology, people don’t want to spend an extra second waiting to load a site. So, if you manage to save a second, you can gain 60% more audience in that process. In 2012, Amazon stated that a single second delay on-site loading will cost them $1.6 Billion in sales. So, a WordPress caching plugin becomes a necessity.

Reduced CTR

Although very few websites run on the scale of, there is a conversion factor that still impacts badly due to slow speed. It is estimated that, if your site takes more than 3 seconds to load, 40% of the visitors lose patience and leave your site. This number will cost you a 7% conversion reduction each day. This number is a lot if considered on a small scale business. WordPress has many caching plugins to tackle these situations.

Fall on site’s ranking

If your site operates at a slow speed, Google will enlist your site as a low ranked site according to Google Page Speed rules. Once you get a bad impression from Google, you will continuously lose traffic. People won’t be able to find your page easily and thus will lower your site’s value. A simple WordPress caching plugin may save the day.

What WordPress caching plugins can do for you?

A caching plugin optimizes your website and reduces data loads from the content. When a visitor tries to access any page on your site, there is actually quite a lot of things going on in the background. The page loads throughout a series of algorithms, data charts, queries, codes, etc. As it is a dynamic system, it takes time to load.

A WordPress caching plugin, on the other hand, transforms the dynamic page into a static page, skipping all those steps behind. Thus, it takes only a second to load. The result is, your visitors love your site.
