What does the Website SEO Checker scan?

Meta titles and descriptions, Open Graph and Twitter Cards, canonical tags, redirects across http/https and www/non-www, robots meta, HTTPS, mobile responsiveness, and JSON-LD structured data.

How does the canonical and redirect audit work?

We test all primary URL variants, follow redirects, and verify that the final destination URL matches the declared canonical tag.

Can I compare two scans?

Yes. Compare mode highlights changes between scans so you can see what was fixed or introduced.

Do you store my URLs or scan data?

Scans are not stored by default. Compare mode uses browser session storage and clears automatically.

Can I export or share reports?

Yes. You can export reports as PDF or CSV, or embed the free widget on your own site.

What should I fix if multiple versions return 200?

Choose one preferred URL, redirect all others, and align the canonical tag with the final destination.

Embed SEO Checker Widget

Q: Is there a rate limit?

Yes. Scans are limited to approximately 30 per IP address per hour (enforced on a best-effort basis), shared across the tool and any embedded widgets.
