    Free Canonical Tag & Robots Meta Validator

    A single wrong canonical or a stray noindex can deindex an entire section of a site. This free validator checks your canonical URL against the page URL, parses your robots meta and X-Robots-Tag directives, and flags conflicts — such as a page that is canonicalised elsewhere while also being set to index.

    Canonical & Robots Meta Validator

    Catch indexing mistakes — conflicting directives, bad canonicals, fragment issues — and copy a corrected snippet.

    Findings

    • OK
      No issues detected. Tags look healthy.

    Corrected snippet

    <meta name="robots" content="index, follow" />
    • Canonicals must be absolute URLs — never relative paths or fragments.
    • Don't combine noindex with a canonical — they send conflicting signals.
    • X-Robots-Tag headers override meta tags; check both before assuming a page is indexed.

    What this tool checks

    • Self-referencing and cross-domain canonical checks
    • robots meta and X-Robots-Tag directive parsing
    • Conflict detection between canonical and indexing rules
    • Validation of directive names and preview values

    Frequently asked questions

    Should every page have a canonical tag?

    Yes. A self-referencing canonical on every indexable page is the safest default and prevents parameterised or duplicated URLs from splitting signals.

    Can I use noindex and canonical together?

    It is best avoided. Combining them sends conflicting signals; Google may ignore the canonical entirely. Choose one strategy per URL.
