Best WordPress Cache Plugins
As your WordPress website grows, with the publication of new content and the installation of additional plugins, it will, unfortunately, start to slow down. Even a fresh installation of WordPress can suffer from poor performance during spikes of high traffic or if you’re using a low-quality web host.
When it comes to page speed and loading times, an improvement of just a single second can have huge implications for your bottom line. For example, back in 2012, Amazon estimated that if their website loaded just one second slower it would cost them $1.6 billion in sales; and this number has surely only increased since then.
You’re probably not operating quite on Amazon’s scale, but slow loading times are still costly. According to Kissmetrics, 40% of your visitors will lose patience and leave your site if your pages take more than three seconds to load. A single second of delay can reduce your conversions by 7%.
Even if you’re not selling anything from your site, you probably have some goal in mind. Whether that goal is more email subscribers, more social shares, or just more page views and discussion, slow loading times will hurt your goal conversion rates.
Furthermore, Google uses page speed as a factor when determining where to rank your content in its search engine results pages. So, if you want greater search engine visibility and more traffic from sites like Google, you need to speed up your website.
No matter the purpose of your website – whether it’s to promote products and services or simply build an audience – higher bounce rates, reduced conversion rates, and decreased search engine rankings hurt.
In short, caching plugins help WordPress work more efficiently. By default, each time a page on your WordPress website is accessed by a visitor, the content is generated dynamically with lots going on in the background, including multiple database queries and code executions.
A caching plugin will create a static version of your content, removing many of the steps that take place when a page is generated dynamically. The result of this is faster loading times and happier visitors.
Therefore, if you want to improve your site’s SEO, increase its conversion rates, and offer your visitors a more enjoyable user experience, installing a caching plugin is a quick and effective way to do so.
There are countless free and commercial WordPress caching plugins available. However, to make the comparison more manageable, only the top 8 best WordPress caching plugins were selected.
Only free plugins with a user review rating of at least four stars out of five at the WordPress Plugin Directory, which had also been updated within the last two years, made the final list. Commercial plugins that appeared to have a positive reputation and decent feature set were also included.
When selecting the plugins for this comparison, we looked for options that were easy to setup and offered speed improvements in just a few clicks, rather than requiring advanced configuration. If you have the time and abilities, then it’s possible you could configure these caching plugins for your website’s specific setup and get better results, or find more advanced alternatives not included in this collection. However, for the purposes of this comparison we were looking for the fastest plug and play options.
