Google has updated its search help documentation around canonicalization this morning. The Google Search Relations team split in three distinct sections and updated a lot of the content to provide clearer details around how Google Search and canonicalization works.
The three sections include:
- What is canonicalization
- How to specify a canonical with rel="canonical" and other methods
- Fix canonicalization issues
All of this use to be on a single help page, which you can review on the Wayback Machine over here to compare.
With this, Gary Illyes from Google dropped another LinkedIn tip on the topic of canonicalization, he wrote:
Friday ramble: you can stack canonicalization signals to strengthen that hint.You have a rel=canonical pointing from A to B, but A is HTTPS, it's in your hreflang clusters, all your links are pointing to A, and A is included in your sitemaps instead of B. Which one should search engines pick as canonical, A or B?
If you just change the URLs from A to B in your sitemaps and hreflang clusters, combined with that rel=canonical it might already be enough to tip over canonicalization to B. Change the links also, and you have an even greater chance to convince search engines about your canonical preference.
Recently, Gary also mentioned to use absoluate URLs for rel-canonical.
So check out these new docs and learn a bit more on canonicalization and Google Search.
