So I have a potential client that has been slapped by the penguin. His site is ranked for a real good keyword phrase, but he has like 64k backlinks from the same site. Most of them are footer links and it is a relevant niche (about 60k). I am about 90% sure that this is why his homepage is getting penalized because it is all the same anchor text. I was thinking about adding the highest quality links I can, but I'm afraid it might be a difficult task. This is his biggest money making site so I am not sure if a 301 redirect will be acceptable. Should I get the footer links removed or just try to build quality on top from now on?
