Hello, we apologize for the issue you are facing with duplicated canonical tags on your website.
To address the duplicated canonical tags issue caused by WordPress default settings, you can use Rank Math to set a custom canonical URL. Here’s how you can do it:
- Edit the post/page where the duplicate canonical tag is present.
- Navigate to the Advanced tab of Rank Math in your editor. If you cannot find the Advanced tab, please enable the advanced mode from WordPress Dashboard → Rank Math SEO → Dashboard.

- Under the Advanced tab, in the Canonical URL field, enter the URL that you want Google to index.

- Save your changes.
By setting a custom canonical URL using Rank Math, you can override the default canonical tag added by WordPress. This should help resolve the issue of duplicated canonical tags on your website.
If you need further assistance or have any other questions, please feel free to reach out to our support team directly here. We are here to help!

Hello,
Thank you for your patience.
Rank Math already adds a self-referencing canonical URL on your indexed posts/pages. The canonical URL you’re seeing as duplicate could be added by on of your plugins or active theme.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), to determine that, please follow this troubleshooting guide:

Here is a video you can follow as well: https://www.youtube.com/watch?v=FcIWRhcUP2c
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
