This is a first for us so I want to get it right. A plumber client really wants to get more paid backlinks. We already have a list of prospects thanks to SEMRush, but I was just wondering what websites are definitely worth the money on when it comes to paid backlinks? I recall reading here before that someone purchased a $400 backlink from a popular website and another person made a reply implying it's normal practice and that there are other "pillar" websites worth the money on backlinks, but I can't seem to find that post.
