A slow site loses visitors. Here are the highest impact ways to speed up WordPress.
Use Caching
A caching layer serves stored copies of your pages so the server does less work on each visit.
Optimize Images
Compress and correctly size images, and serve them in modern formats to cut load times.
Choose Fast Hosting
Quality hosting with SSD storage and a content delivery network makes a large difference.
Minimize Plugins
Every active plugin adds work. Keep only what you use and remove the rest.
