What is caching, and how it speeds up your site

Caching is one of the main reasons a well-built website feels instant. In simple terms, it stores a ready-made copy of your pages (or parts of them) so they don't have to be rebuilt from scratch for every visitor.

Why it helps

• •Pages load much faster when served from a cache.
• •Your server handles more visitors without slowing down.
• •Combined with a CDN, cached pages load fast worldwide.

You shouldn't have to think about it

Caching can be technical to set up, but on a well-built, well-hosted site it's handled for you. It's one of the invisible things that separates a fast site from a sluggish one.
