How to use Declared Canonical Mapping Review

Review page-level canonical declarations as a bounded local graph before checking a live deployment. Self hints, absent targets and cyclic chains remain distinct, while supplied indexability and cross-origin destinations remain evidence for human review rather than an automatic search-engine verdict.

  1. Enter input.
  2. Choose the settings for declared canonical mapping review, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 500 explicit page records, 100,000 JSON characters, 4,096 characters per absolute HTTP(S) URL and planned row/cycle output budgets. URLs use browser serialization; credentials, fragments, backslashes and controls are refused.
  • Every edge and indexability value is supplied, not fetched or measured. A canonical is a hint; the tool cannot establish Google/Bing canonical choice, live headers, crawlability, indexability or traffic. Cross-origin hints are not automatically invalid.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Does a chain ending at a self-declared page prove that Google chose it?

No. It only describes your supplied graph. Search engines can choose a different canonical using other signals, and the target’s actual indexability and deployment still require independent checks.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
