Free ToolIndexability Checker
Check whether a live page can be indexed, then spot redirects, noindex directives, status-code issues, and canonical conflicts in one pass.
What is an indexability checker?
An indexability checker answers a simple but high-stakes SEO question: can search engines actually index this page, or is something technical getting in the way? Instead of reviewing one signal at a time, it combines the final HTTP response, redirect behavior, canonical tags, HTML robots directives, and response headers into a single decision.
This matters because indexing problems rarely come from one obvious failure. A page can return a 200 status code but still be excluded because it carries a noindex directive. It can also look fine in a browser while canonically pointing somewhere else, which tells Google that another URL should rank instead.
This free indexability checker is built for practical audits. Paste a live URL, review the redirect path, confirm whether the page is self-canonical, and see whether any header-level or HTML-level directives are likely to stop indexing before you spend time debugging sitemap or content issues.
How to read indexability checks
Start with the verdict, then validate the reasons behind it. A healthy page usually ends on a 200 response, has no noindex directives, and either self-canonicalizes or clearly points to the preferred version you expect search engines to index.
Check the final response
If the final URL returns 404, 410, 401, 403, or a server error, indexing is blocked before tags even matter.
Review directives
A meta robots noindex tag or an x-robots-tag header will usually override otherwise healthy page content.
Confirm canonical intent
If the canonical points somewhere else, search engines may index that target instead of the page you tested.
Example: if you test a product page and see 200 + self-canonical + no robots restrictions, the page is technically indexable. If it still is not ranking, the problem likely sits elsewhere, such as weak internal linking, duplicate content, or low crawl priority.
Different example: if a page returns 200 but the checker finds meta name="robots" content="noindex,follow", the page can be crawled but should not be indexed. That is a classic staging-to-production mistake during launches and migrations.
Common use cases
- Checking whether a newly published landing page is blocked by a stray noindex tag.
- Auditing redirect cleanup after URL migrations, CMS changes, or site restructures.
- Reviewing canonical behavior on parameterized pages, faceted navigation, and duplicate templates.
- Debugging why a page is excluded from Google Search despite appearing normal in the browser.
- Validating client deliverables before handing off a technical SEO audit or launch checklist.
FAQ
What does a free indexability checker actually test?
It checks the final HTTP status code, follows redirects, reads canonical tags, inspects HTML robots directives, and reviews x-robots-tag headers so you can see whether search engines are likely to index the page.
Can a page return 200 and still fail an indexability check?
Yes. A page can return 200 but still be blocked from indexing by a meta robots noindex tag, an x-robots-tag noindex header, or a canonical that points to another URL.
What is the difference between noindex and canonical?
Noindex tells search engines not to include the page in search results. A canonical tells search engines which version of similar pages should be treated as the preferred URL. They solve different problems and can conflict if used carelessly.
Why does the checker warn about redirects if the final page loads?
Redirects are not always harmful, but they create an extra hop for crawlers and can hide linking or canonical mistakes. For important pages, you usually want internal links, canonicals, and sitemap entries to point directly at the final destination.
Does a missing meta description block indexing?
No. A missing meta description does not stop indexing, but it weakens how the page can appear in search snippets. This checker shows those softer SEO issues separately from true indexing blockers.
Can this indexability checker review PDF or non-HTML URLs?
Partially. It can still inspect status codes, redirects, and x-robots-tag headers, but page-level HTML signals like canonical tags and meta robots are only available on HTML responses.
