Optimizing WordPress Performance on Shared Web Hosting
3 likes4,612 views
This document discusses performance tweaks that can be made for WordPress sites on shared hosting. It is divided into three acts: inside WordPress, on the shared server, and off the shared server. Inside WordPress, it recommends right-sizing images, checking for 404 errors, keeping the database under control, and using caching plugins. On the shared server, it suggests updating to newer PHP versions, cleaning up the database, and using CloudFlare. Off the server, it only recommends using CDNs like CloudFlare for their free benefits.
