I have a keyword that i am hoping to top google with. The top 3 in google are, amazon, ebay, youtube. They have zero backlinks to that page and low PA. But i understand that these are heavyweight websites which count for an awful lot when ranking. The rest of the top ten has a couple of rivals going after the same stuff as me and some news websites. One rival has 150k backlinks. One news article has 800 backlinks. Does this sound like an easy or hard keyword?
