FAQ

Questions

Is this the same as PageSpeed Insights?

Yes. SearchCon runs Google's PageSpeed Insights (Lighthouse) and the Chrome UX Report behind the scenes, then your AI explains the results.

Why do lab scores and Core Web Vitals differ?

The lab test is one simulated visit and reflects changes straight away. Core Web Vitals are a 28-day average of real Chrome visitors, so fixes show up there gradually.

Is there a limit?

Each account can run 100 live lab tests a day. Real-user Core Web Vitals don't count toward it.

Can I test any website?

Page speed tests run on pages from your own Search Console sites.
