Hello,
Thank you for your query, and we are so sorry about the trouble this must have caused.
Please head on over to your WordPress Dashboard > Rank Math > General Settings > Links and enable this option here?

This should add a “Nofollow” attribute automatically on your external links. More on that here:

If you’re unable to see this option, you may also need to make sure that Advanced mode is enabled:

We hope that helps, and please don’t hesitate to get in touch if you have any other questions.
Thank you.
Thank you for your reply, I only want to mark the outerlinks that go to a specific domain as nofollow (only the affiliate links). I don’t want all the external links from my site would be a nofollow. Is it possible?
Hello,
Yes ofcourse that is possible.
When you enable the “Nofollow External Links” toggle and scroll down you will see another option show up as “Nofollow Domains”.
Enter the specific domain that you want to add nofollow attribute for.
Please refer to the screenshot below :

We hope that helps, and please don’t hesitate to get in touch if you have any other questions.
