How slow is your site really?

Not a guess from your HTML. Speed comes from Google's own data: what real Chrome visitors see where Google has it, otherwise its mobile test. Then we open your pages in a real browser and measure how much you ship, how many requests it costs, and what blocks the first paint.

Speed from Google, the numbers it ranks your site on
Page weight and request count from the network log
Render-blocking scripts and stylesheets, per page
Oversized images, with the ones worth fixing first

Run your free audit

Real browser measurement takes a minute or two.

Measured, not estimated.

Most free speed tools read your HTML and infer. We take speed from Google, so you can check it yourself, and load each page in a real headless browser to take weight and requests from the network log. That costs five to ten seconds a page, so we check five rather than thirty.

If you want every page measured, that is the full site audit.

Performance audit FAQs

Google's tool is excellent, and its speed number is the one in this report: real visitors where Google has enough of them, otherwise its mobile test. What we add is scope. PageSpeed tests one URL; this loads several of your pages and gives you the median and the p75 weight and requests across them, so you see whether a problem is one page or your whole template.

Because we measure rather than estimate. The score is a median, so five representative pages tell you the same thing thirty would, without leaving you waiting.

The median is the typical page. The p75 is the heavier quarter of your pages. If those two numbers are close, your site is consistent. If the p75 is much worse, something specific is dragging, and the per-page table will show you which page.

It means the headless browser was unavailable when your audit ran, so page weights and requests were inferred from your HTML instead of measured. We tell you rather than quietly presenting a guess as a measurement. Re-run later for measured figures.

Yes for speed: it is Google's figure for phones. The weight and request measurements are a desktop pass; the full site audit adds a separate mobile pass across more of your site.

Images, almost always. After that, render-blocking scripts in the head and third-party tags nobody remembers adding.
