How to read your result
One URL at a time, with public DNS pinning, redirect checks, a 1 MB response limit and a 10-second page deadline. Optional Google PageSpeed mobile Lighthouse uses an 18-second deadline and a configured API quota. Unknown stays unknown. Results can be cached for 6 hours.
Example: paste three business homepages, one per line. An HTTP 503 is a dated server observation. A mobile lab LCP of 4,200 ms is a reproducible measurement to investigate. Neither proves lost sales or buying intent.
Method checked 27 October 2026. Free checks share Margo’s existing service allowance; no payment or card required. Larger discovery and contact enrichment use the product’s reviewed paid flow.

GOOD TO KNOW
A few answers before you start.
Can this find slow or broken website prospects?
Supply up to three URLs from your prospect research. Results show observed HTTP errors and raw mobile Lighthouse metrics where available. Review the evidence; there is no subjective bad-website score.
Are these real-user Core Web Vitals?
No. Lighthouse measurements are lab data under simulated mobile conditions. The bounded server fetch duration includes redirects and body transfer, not browser load time. This tool makes no claim about real-user field performance.
Why is the mobile result unknown?
Mobile lab results require a configured PageSpeed API key and available quota. Timeouts, blocked pages, errors and incomplete audits stay unknown. Availability observations can still be useful.
