I apologize if this is off topic but I am in need of this solution.
Actually i want to apply
Rel=nofollow to the external links under the text in the body.
This is to inform the Facebook that its a good page.
Thus the Rel=nofollow should be get applied to the facebook link i.e external link. But also it shouldn’t be applied on internal links.
Kindly let know the solution for it.
