A live server-response test
The server requests the public URL, records network timing from this hosting location, follows a limited number of safe public redirects and reports response headers and transfer size. No Google API key is required.
Test a public page without a Google API key and review DNS, connection, TLS, TTFB, total response time, redirects, transfer size, compression and cache headers.
Enter the details, then run the check.
Ready.

This is not Lighthouse and does not render the page like Chrome. It cannot measure LCP, INP or CLS. Network timing depends on the test server location, CDN routing and current load.
No single SEO or performance metric decides rankings. Use the output to identify a specific technical or content issue, then verify the deployed page and Search Console data where relevant.
Text-only tools run in your browser. Live URL tools send the public URL you enter to this website's read-only diagnostic endpoint so the server can fetch public data that browsers often cannot access directly.
