rankmath primary taxonomy selection

Hello @exactprecisions,

Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.

It seems to be working fine on our end.

Assuming you are using the latest version of all the plugins, themes, and WordPress (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.

You can follow this video tutorial as well:

Looking forward to helping you.

It does the same thing with default theme and no plugins active.

pages with multiple categories are duplicated like so
example.com/category1/page-name
example.com/category2/page-name
example.com/category3/page-name

Hello @exactprecisions,

This is quite normal with WordPress due to the permalink structure you have configured.

However, Rank Math will help you properly add a canonical link to tell Google which URL version should be shown on the search result page. For example, suppose that “category2” is your primary category, then all of the URLs will contain this canonical URL: “example.com/category2/page-name”. Hence, Google knows which correct URL to use and will ignore the other duplicates.

You can check the canonical URL in the page’s source code like so: https://i.rankmath.com/i/5BDHzo

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
