Just investigating some backlink profiles of high ranking affiliate sites for a skincare niche.
I keep finding all these white footer extensions inserted into fairly authoritative and genuine websites with spammy anchor text links pointing back to a few sites.
At first I thought the affiliate must own all these sites but then I realised the sites must had been hacked.
The site in question has been ranking high on first page for sometime now - at least 2 months.
Does anyone know what these hacked footers are and what is their life expectancy in SEO terms?
