The keyword is a product category (something like 'tennis shoes'). Looks to good to be true, right? Maybe it is... Made me think of something I read a while ago. For some types of keywords it is just not possible for Amazon affiliate sites to rank. Could this be the case here? Even for all long tail keywords (3,4 and 5 words long) I could not even find 1 Amazon affiliate ranking top 10. Surely I am not the only 1 who has found this keyword... What do you think?
