Free SEO validator for any URL
An SEO validator answers one question: did the fix work? It runs the same Google Lighthouse pass and crawlability probes as a full audit, but presents the result as a pass / fail grid so you can confirm a change has shipped, a regression hasn't snuck in, or a competitor's claim about their site actually holds up.
It's the right tool for the moment when you already know what's wrong and you just need a clean verification — not a 1,200-word walkthrough. Paste the URL, read the row that changed, move on.
Common validation workflows
- Post-deploy smoke test. Validate the live URL minutes after a release to confirm Lighthouse scores didn't regress.
- Ticket closeout. Validate a specific signal — sitemap, HSTS, meta description — before marking the SEO ticket done.
- Competitive claim check. Validate that a competitor's "we score 95+ everywhere" claim is actually true.
- Sales handover. Validate a prospect's site before the call so you can speak to the specific gaps that matter.
