Free page speed check

Slow pages lose visitors and rank lower, most of all on phones. We run Google’s own speed test on your page, add what real visitors experience, and explain the fixes in plain words.

Test a page’s speed

  • Free
  • No account needed
  • Uses Google’s test

What the check looks at

  • Real visitors (Core Web Vitals): how fast the page loads, reacts to taps and stays still for people using Chrome over the last 28 days. Google uses these in ranking. Smaller sites may not have enough visits yet.
  • Google’s test phone: a fresh load on a mid-range phone and a slower mobile connection, the same test as Google’s PageSpeed Insights.
  • What to fix: the suggestions that would save the most time, such as oversized pictures, unused code, slow servers and files that block the page from showing.

The score is Google’s performance score for phones. It moves a few points between runs, so look at the trend, not one number.

Want the rest of the page checked too? Use the SEO check for one page, or the SEO audit for the whole site.
