One reason we love SiteGround is its comprehensive caching solution, SuperCacher. It sits on SiteGround’s own servers so it’s much faster and better tailored to your site than plugin-based solutions like W3 Total Cache, and so if you’re using it you basically don’t need any other WordPress caching solution.

If you’ve ever migrated a WordPress site to new hosting, you know that one of the many ways the process can turn confusing is DNS caching by your internet service provider (ISP). It looks as follows:

In this video guide, I explain (with a bit of help from my dog, who wanted attention) how to force browsers to load a CSS stylesheet from scratch on every page load. The purpose of this is to disable browser caching of that stylesheet, since in some situations outdated CSS styles can lead to a broken user experience.

“Caching” is, generally, the solution you hear offered for most performance problems a WordPress site has. For things other than WordPress sites, too, caching is one of the easiest and most effective ways to increase performance of software without investing in new hardware. (Using the exact same software on hardware that is significantly faster is easier, but probably not cheaper…)
