Make WordPress faster: the biggest gains

Six things that matter most, without having to be a developer.

1 min read · updated 10 Oct 2026

A fast site ranks better in Google and sells more. These changes give the most:

1. Fewer and better plugins

Every plugin loads code. Remove what you don't use, and pick one good plugin per task.

2. Shrink images

Don't upload photos larger than 2000 pixels, and use WebP. This often cuts your load time in half.

3. Turn on caching

On our WordPress hosting, server caching is on by default. Want more? Use Netslim Speed: page cache, WebP and smart script loading in one plugin, with a speed check that shows what you can still improve on your server. Never use two cache plugins at the same time. They work against each other.

4. A light theme

Heavy page builders load a lot of extra code. A light theme is often twice as fast.

5. Keep up with updates

Newer versions of WordPress and PHP are faster and safer.

6. Measure

Run the free website check on our site. You see right away where the gains are.

The free website check gives your site a score and puts the biggest gain at the top.

Even faster for large sites

With Netslim Edge, pages for visitors without an account are served from the edge cache, with HTTP/3 and compression, and you take load off your own server.
