SEO Basics Check

Checks a page's on-page SEO signals, robots.txt, sitemap.xml, and Core Web Vitals performance data — live, in one run.

Checks the homepage of the domain you enter. The performance check can take up to 30 seconds on a cold run.

Out of scope, by design: this checks a single page's basics, not a whole site. It does not crawl or check for broken links, does not test mobile rendering/interactivity (only the presence of a viewport tag), and does not do backlink analysis, keyword research, competitor comparisons, or hreflang validation.
