Hi all. I came across a competitors websites backlinks, which has a very specific pattern. Obviously it's a SEO-product he has bought from somewhere - and I don't know if it's a time-limited product. Method-description: His backlinks are only part of a footer on many many sites. Someone has to own a lot of sites with different content and sell 5-10 links in the footer. It's a sudden increase in backlinks, which is why I think he has bought a service. What is this kind of method called? Where you can buy many unique footer-links from a ton of websites? This is not blog-comment spam, and it seems to work very good. Thanks for the help.
