PageSpeed Test

Runs a real Google PageSpeed Insights check (performance, accessibility, best practices, and Core Web Vitals) alongside the Forge Website Diagnostic Engine's own SEO/technical checks — one report, mobile-focused, with what to fix first.

Find out how fast your site actually is for a real visitor, and exactly what to fix first.

We'll run a real PageSpeed check on your mobile homepage — this can take up to 20-25 seconds.

How this works

This checks your homepage on mobile — the device most local-business customers actually browse on. Performance, accessibility, and best-practices scores plus Core Web Vitals (LCP, CLS, INP, FCP, TTFB) come from a real Google PageSpeed Insights run when available; title, meta description, schema, headings, HTTPS, images, and mobile-friendliness come from Forge's own Website Diagnostic Engine, always, regardless of whether Google's data is available.

Questions about this tool

No — it's free, and it never touches your Google account. It calls Google's own public PageSpeed Insights API to check your site the same way Google itself does.
