I have had it happen to me. Someone, I assume purchased, maybe 100 links from very low quality blogs that obviously were paid for posts. My site has suffered since. I used to be top 5, consistantly. Now I am 8-15. /*tom*/
I'm desperate for proof of this - can anyone give an example of the "bad" links they have received - PM them to me if you like
Hmm I've seen possible eveidence of this for one of my clients recently. Not neccesarily one site but a lot of irrelevant spammy footer backlinks (which for some reason they built themselves!) seems to have affected them...
