I got one of my websites on a Cloudflare free plan to 95% Cached, but I don’t remember what I did to achieve it.
Another one of my websites is at 48% Cache. Here is what I did to achieve it:
Installed the official Cloudflare plugin for WordPress. This seems to boost cache percentage by 20-30%.
Installed WP Cloudflare Super Page Cache.
I have a Cache Everything page rule with Edge Cache TTL of 1 Month
I have set up WordPress cache headers as described in this guide: How to Set Up Custom Headers – OpenLiteSpeed as I am using OpenLiteSpeed.
Right now I am at 48% cache. Does anybody have better ideas?
Also, if I set Edge Cache TTL will Google Analytics break down, as Cloudflare is stripping the cookies?
