Google Updates Canonicalization Guidance: Two‑Week Window for Content Fixes

Google has added a new section to its canonicalization troubleshooting guide that explains how long a content fix can take to register in Search. The updated section states that even after content is fixed, Google may keep pages in a duplicate cluster for up to two weeks. The guide also notes that pages can split out of a cluster more quickly when the difference between the new content and the other pages in the cluster is more distinct. The fix is content‑related, not a redirect, rel=canonical, or server misconfiguration. Google’s guide advises checking the Google‑selected canonical in URL Inspection and considering whether it serves searchers better than the one you would prefer. The article also notes that Google has revised its canonical guidance multiple times in recent months, including updates to JavaScript docs for injecting canonical tags.

The article explains that Google groups pages together when it perceives them to have the same or very similar main content, then selects one as the canonical. Resolving the issue involves ensuring the clustered pages are different enough so that Google no longer groups them. The two‑week window covers content fixes, and Google advises reserving the Request Indexing option for the most critical URLs. The guidance is part of a staged rollout, and Google has not committed to a firm launch date for the update.

In practice, if you have duplicate content issues, you should focus on making the content distinct, then use Request Indexing for critical URLs and monitor the canonical status over the next two weeks.
