Free tools, no account needed
Each tool reads one public page you name, once, politely. For every page of your site, connect Search Console and let the full product do it.
Title and description checker
Is the title the right length, is there one H1, a canonical, a language, and is the page indexable?
Core Web Vitals lookup
What real Chrome users experienced on this page in the last 28 days: loading, responsiveness and visual stability.
What Google sees
The page as a crawler reads it: headings, text, links, images, structured data, and whether JavaScript changes any of it.
This is one page. Your site has hundreds.
Connect Search Console and the full product checks every page, ranks what matters by impact, and proposes the fix. Free trial, no card.
