First of all, users will bounce away from a website that’s slow to load. Instead of waiting for the page to load, they’ll just click the back arrow and find a site that’s faster. In fact, according to Portent, website conversion rates drop by an average of 4.42% with each additional second of load time (between seconds 0-5).

If you’re a retailer, here’s an important stat to know: According to Unbounce, nearly 70% of consumers admit that page speed impacts their willingness to buy from an online retailer.

In addition, Google’s 2021 Page Experience Update will give fast pages a ranking boost in search results.

If you want your site to rank well and perform well, speed is essential.

What Does a WordPress Cache Plugin Do?

You’ve heard that a cache plugin can speed up your site, but how does it work? We’ll break it down into simple terms for you.

When your website loads, there are a whole bunch of different parts that load. Your images, the code that tells your website how to look, the code that tells your website how to function, and your on-page content are a few of the bits and pieces that have to load.

Depending on how big all those pieces are, it can take some time for them all to finish loading, adding to the overall time your site takes.

A cache plugin optimizes some of the loading processes in a few different ways, but mostly, it makes a copy of your page the first time it loads, then uses that copy to show users that visit after. This way, the whole site doesn’t have to load every single time. It puts a copy of the page into your “cache,” which is just a fancy way of saying storage space.

Some WordPress cache plugins go beyond simple caching to give you some extra settings that’ll speed up your site even more.

Let’s dive into our list of the top WordPress cache plugins!
