What we test

The same measurements as Google PageSpeed Insights, in a clear report that explains each issue and points to the exact files or elements.

Performance
How fast your page appears and responds, with the Core Web Vitals LCP, CLS and TBT and a loading timeline.
Real visitors
Data from real Chrome users over the last 28 days, for this page and for your entire website.
Accessibility
Contrast, labels, headings and keyboard navigation. So everyone can use your site with ease.
Best practices
HTTPS, secure settings, console errors and modern web standards.
SEO
Whether search engines can find, read and properly display your page in search results.
Mobile and desktop
Two separate tests: a mid-range smartphone on 4G and a desktop on a fast connection.
