Missing or inconsistent canonical

Search engines can only rank what they can crawl, render and understand. Duplicate URLs split ranking signals without a canonical. Left unfixed, this class of issue quietly limits how well your pages are indexed. It is exactly the kind of mechanical work that sits in a backlog because finding the responsible file takes longer than the fix itself.

An audit detects this issue on your rendered pages and points it at the template or source file most likely behind it, and prepares a patch with what to adapt and how to verify it. You or your AI editor apply it in your own pull request, and the pull-request check confirms the issue cleared.
