How To Run a Speed Test:
Using the form below, enter your URL and test location and then hit the button.
The tool will then test your site in around 90 seconds and
provide a detailed list of recommendations. Note that the larger your page or the slower it loads the longer the test will take.
It’s usually best to do a few tests to get an average speed as a single test may not be a true reflection of overall site speed.
The tool retains tests for 12 months – there’s a link on the test page to the speed test history for a domain.
We regularly update the tool with new recommendations and advice based on what we’ve learnt through our WordPress Site Speed Optimization Services.
The Metrics You Should Aim For:
To give the test some context, ideally we want our speed timings looking something like this:
- TTFB or Time To First Byte 0.1-0.3 seconds (this is where is should be in the country where the site is hosted, 0.2-0.6 internationally)
- FCP or First Contentful Paint at or under 1.8 seconds
- LCP or Largest Contentful Paint under 2.5 seconds
- Page Size or Page Weight under 1.5mb, ideally but not always possible
Hitting these numbers will get you in the “good” range for Google’s Core Web Vitals scores and have the site loading lightning fast.

We’re not using Google Pagespeed Insights or Lighthouse engine
You might have noticed when you search Google for site speed test tools that they all roughy look the same with the same recommendations. Our tool is different. Unlike most of the other WordPress site speed tools ours does not rely on the Google Pagespeed Insights Lighthouse engine and is specifically built for WordPress sites.
It has a basic AI engine that we built up over time providing our custom recommendations for various tools and plugins that we’ve built after optimizing 5000+ sites.
A note on information, warnings and errors in speed test tools:
Many marketers and web developers using site speed and SEO tools often take recommendations as fact but that’s a mistake. The recommendations our speed test tool and any other software you’re using like SEO audit tools needs to be interpreted in the context of your site.
Just because a tool provides a recommendation doesn’t necessarily mean you should take action. For this reason, as much as possible with SiteSpeedBot we’ve aimed to avoid things like scores and errors.
When reviewing and digesting the recommendations from SiteSpeedBot please interpret them in the context of your site and what you’re looking to achieve.
We built this tool based on our experience optimizing thousands of WordPress websites through our speed optimization service.
