How to Speed Up WordPress Website in 2026

A slow site costs you readers and rankings. The good news is that most WordPress sites lose speed in the same handful of places, and each one is fixable.

Add page caching and a CDN

Caching turns dynamic PHP into ready-to-serve HTML. A CDN then hands it out from a location near your visitor.

• Enable page caching at the server or plugin level.
• Serve static assets through a CDN.
• Exclude cart and account pages from cache.

Tame your images

Images are usually the single biggest payload on a page.

• Serve WebP or AVIF.
• Set explicit width and height.
• Lazy-load everything below the fold.

Audit plugins and hosting

Every plugin is code that runs on every request. Treat them like a budget.

• Delete, do not just deactivate.
• Move to modern PHP 8.2+.
• Choose hosting with object caching.
