There are a few types of caching and it can get very technical and confusing! For the purpose of this article, we will focus mainly on client-side caching.Ĭaching is a method of storing some information about a website in your browser ’s memory so the next time you come back to the same website, it will load faster because it “remembers” some things that were there the first time. While not unique to WordPress, if you have a WordPress website, you have probably heard of caching or browser caching, and been told a few times to “clear your cache.” (Note, this is different from clearing your CASH, which is not usually a good idea).
