A slow site costs you visitors and revenue. Here are five changes that make the biggest difference with the least effort.

1. Use a caching plugin

Caching turns dynamically generated pages into static files, cutting load times dramatically.

2. Compress your images

Large, uncompressed images are the most common cause of slow pages. Compress before you upload.

3. Pick a lightweight theme

Bloated themes ship CSS and JS you’ll never use. Fewer files means faster pages.

4. Enable a CDN

A content delivery network serves your assets from a server physically closer to your visitor.

5. Keep everything updated

Newer versions of WordPress, PHP, and your plugins are almost always faster than older ones.
