How to choose a WordPress caching
plugin for your site

Choosing a caching plugin for your site can be
difficult. They’ll only conflict with one another if you use two or more at
once, and they each offer similar features in different ways. Plus, caching is
a highly technical topic, which can make it even more difficult to determine
which option to go with.

Check with your host first. They may implement
caching for you at the server level. Some even limit the types of plugins you
can install. Kinsta, for instance, disallows all caching plugins except WP
Rocket on its servers. It disables WP Rocket’s caching functionality by default
but allows you to use its other features.

You should also ensure the plugin has starting
and renewal rates that match your budget.

Because site speed is so imperative for SEO
and user experience, it’s best to choose a plugin that offers several different
ways for you to optimize your site. These plugins include solutions like WP
Rocket, WP Fastest Cache and Comet Cache.
