Someone already heard about it? I saw on a brazilian renowned blog. I have a niche blog that sells products (links on the signature) and I'm trying to catch the first page for the main keyword. But I use a lot of links of Amazon, to help people to find the specified products that I talk about (and to make money! :mrgreen. So, any tips? Maybe the best is to remove all the links and make only links pointing to an online store inside a special page on the blog? Thanks for the help, people!
are you saying having links to Amazon has reduced your ranking? I dont think that would be the case unless you are overtly linking to Amazon and Amazon only.
