How to read canonical and indexability signals
A page can have strong content, relevant keywords and a good layout and still fail to get indexed if it returns the wrong status, points to another canonical URL, carries noindex or is blocked by robots.txt. This canonical checker brings the main technical indexing signals into one quick view so you can confirm whether Google can index the right URL.
Technical signals to verify
Check that the HTTP status is 200, redirects are intentional, the canonical target is reachable and meta robots or X-Robots-Tag headers do not contain unexpected noindex directives.
When this matters for SEO
It is especially useful after migrations, CMS changes, multilingual launches, duplicate-page cleanup or robots.txt edits. Before improving content, confirm that Google can index the right URL.
Indexability before rankings
In an SEO agency workflow, indexability comes before semantic optimization. If the page is noindexed, canonicalized to another URL or blocked from crawling, even the best SEO content may fail to generate organic results.
A technical tool for fast audits
This free SEO tool is designed for quick technical checks. It does not replace a full crawler, but it helps spot indexing errors, redirects, non-self-referencing canonicals and X-Robots-Tag headers that deserve attention.
Issues that block organic growth
Accidental noindex tags, canonicals pointing to the wrong page, redirect chains, 4xx or 5xx statuses and robots.txt blocks can stop a page from competing. Before discussing better content, confirm the URL can be crawled, indexed and consolidated correctly.
Canonical checker for duplicate pages
Canonicals matter when variants exist because of parameters, filters, tracking, sorting or similar content. The best canonical checker does not only confirm that a tag exists; it also checks whether the target is coherent and reachable.
Indexability and SEO migrations
After a migration, template change or multilingual launch, this tool helps test sample URLs. It is a fast way to see whether redirects, canonicals, robots directives and HTTP status codes send consistent signals to Google.
Connect it with on-page checks
Once indexability is confirmed, it makes sense to review titles, meta descriptions, H1s, headings and content. That is why this indexability checker links into the rest of the SEO tools collection.
