Canonical URL Mapping Template
Map duplicate public URLs to a justified preferred version while keeping redirects, internal links and sitemap signals consistent.
When to use this template
Use this when the same public content is reachable through several hosts, parameters or paths and the team needs a documented canonical decision.
Choose another approach when: The pages serve materially different user needs, you are trying to hide unrelated content behind a canonical tag, or the mapping would make private information public.
Gather these inputs
- The actual duplicate or substantially similar public URLs.
- The intended preferred address and why it should be the main version.
- The current redirect, canonical, internal-link and sitemap behavior.

Worked example
Illustrative example, not a Crany customer result. Replace every example detail with facts you can verify.
A fictional guide is accessible at /guides/client-handoff and /guides/client-handoff?campaign=launch. Both show the same article. The mapping chooses the clean public guide URL and records whether each version declares that address as canonical. A separate pricing page is not folded into the guide simply because both mention client handoff. Its purpose is different. After a correction, the team verifies the declared signal and internal links. It does not announce that Google has selected the preferred canonical until search-console evidence supports that claim.
How to use it
- Verify content equivalence before choosing a preferred URL.
- Align the applicable canonical, redirect, navigation and sitemap signals through a scoped change.
- Inspect the live result and distinguish your declared preference from the search engine’s selected canonical.
Check before using it
- The preferred page is accessible to the intended public audience.
- The mapping does not collapse genuinely different user intents.
- The chosen signals do not contradict one another without a documented reason.
What to measure
Monitor conflicting duplicate signals and the search engine’s selected canonical when verified reporting is available. A correct tag is a declaration to evaluate, not an indexing or ranking guarantee.
Research and sources
The references explain canonical signals, redirects and sitemap selection. The mapping form is an original change-control aid and does not claim that a preferred URL overrides Google’s canonical choice.
