I often hear people say things like "keyword XYZ has 7 people competing for the keyword" but where do you find that information at?
I havent heard like that. But I have heard "More competition" or "Less Competition". Regularly highly searched keywords have more competition than less searched keywords.
I think I have been unclear... Im talking about competitors bidding on keywords in adsense. Sometimes I have seen people say there are "only 3 bidders for this keyword phrase so its not worth targeting."
