Hello, I’m sorry to hear that you’re facing this issue. It seems like Rank Math is notifying you that the focus keyword you are trying to use has already been assigned to another post on your site. This can happen if you have multiple posts targeting the same keyword, which can lead to content duplication and confusion for search engines.
To resolve this, you can check if the keyword is indeed being used in another post. Rank Math provides a link that allows you to see all posts using the same focus keyword. Here’s how you can find it:
- When you see the notification about the keyword being used, click on the link provided by Rank Math.
- This will show you all posts that are currently using that focus keyword.
If you confirm that the keyword is not being used elsewhere, it might be a glitch. In that case, please reply to this ticket with your site URL so we can investigate further.
Thank you for raising this concern!
