Slow WordPress Site: How to Fix It

Fix it in order, most likely cause first

1. Run a free speed test. Test your site with Google PageSpeed Insights or GTmetrix to see the actual bottleneck. This tells you whether the problem is images, scripts, server response time, or something else, instead of guessing.
2. Compress and resize images. Oversized images are one of the most common causes of slow load times. Most image optimisation plugins handle this automatically, or you can resize images manually before uploading them.
3. Install a caching plugin. If you don't already have one, a caching plugin like WP Rocket, LiteSpeed Cache, or W3 Total Cache often gives the single biggest improvement, since it saves a ready-to-serve version of each page instead of rebuilding it on every visit.
4. Audit your plugins. Deactivate plugins you're not actually using, and check whether any single plugin is loading heavy scripts on every page when it only needs to run on one. Plugin bloat is a common, easy-to-fix cause.
5. Check your hosting. If your time to first byte (how long the server takes to start responding, before any of the page has even loaded) stays high even with caching in place, shared hosting may be the actual bottleneck rather than anything on the site itself.

When to stop and get help

If you've worked through images, plugins, and caching and the site is still slow, the bottleneck is most likely server-side rather than something fixable from within WordPress. At that point it's a hosting conversation, not a plugin one.
