To speed test a WordPress site, enter the URL of any page above. The tool runs Google's PageSpeed Insights on a simulated phone and a desktop and scores each out of 100. Under each score you get five load timings and the fixes that save the most time. It tests the page a visitor loads, so it works with any theme or host and there's nothing to install.
How to test a WordPress site
- 1Open the page you want to test in your browser and copy its URL. Start with the home page, then try a post and any page that sells something, because they can load differently.
- 2Paste the URL above and run the test.
- 3Read the phone score first, then the desktop score. Under each one, check the five timings from First Contentful Paint to Cumulative Layout Shift.
- 4Start with the fix that saves the most time, then work down from there.
Google rates a score of 90 or above as good. A score from 50 to 89 needs improvement, and a score below 50 is poor. Scores come from a simulated load, so they can move a few points between runs. Run a page twice before you trust a change.
The test doesn't sign in to your WordPress admin or change any settings. A page that sits behind a login can't be tested.

What usually slows a WordPress site
WordPress's own performance guide starts with caching. A caching plugin saves your posts and pages as static files, so the server does less work for each visit.
The guide says your theme has a huge impact on speed. A lightweight theme loads faster than a heavy one full of graphics.
Images come next. Compress every image, and think about WebP, which makes smaller files than older formats.
If you think one plugin is the problem, turn plugins off one at a time and test the page again after each one. When the score jumps and the timings drop, you've found the plugin that costs the most.
