After following several tutorials here I found a niche that seems good, but because of my lack of experience I do not know if I should go on with it or not.The first ranked website has 260k of backlinks and the second ranked is Amazon itself. The fifth rank has 60 backlinks and the 9th has 30. Both of these two have a low TF/CF. (They are the reason I thought this would be a good niche/keyword) The others have around 3000 backlinks and one has 30000. Ok, my first question is: am I correct to assume that this is a good keyword? How would you rank this keyword in difficulty from the data I gave you? Second question is: How is it possible for an amazon affiliates site to rank above amazon o page 1? I mean, it sounds illogical. But please enlighten me. Thank you. I used Market Samurai, SEMRush, Majestic and Mosbar to get the data.
