To leverage your browser’s caching generally means that you can specify how long web browsers should keep images, CSS and JS stored locally. That way the user’s browser will download less data while navigating through your pages, which will improve the loading speed of your website.
You will find this option in the WordPress Dashboard -> Settings -> Performance -> Enable this “Leverage Browser Caching” option and after that click on the “Save Changes” button.

That’s it for this tutorial!
