I am responsible for editing posts on a website and right now am assigned to edit a post which has a backlink to the post of another domain. I was told to fix it, since apparently the wrong post was linked.
I was told that losing a backlink does more harm than it initially helped. Would changing the external link hurt the page previous linked? Would it even benefit the other post as much? I understand that two backlinks from the same domain count less than one from another.
