Enter a URL. We load that one page and run up to 15 measurable checks: HTTPS and the http-to-https redirect, server response time and HTML size (measured from our server), mobile viewport tag, title and meta description length, H1 count, image alt text, tap-to-call and contact links, search-engine noindex, and up to 8 same-site links for errors. You get a 0-100 score and your top 3 fixes in plain English. It doesn't claim to measure rankings, traffic or Core Web Vitals.
