When researching a phrase on the KW tool do I need to concern myself with the number of searches on my exact phrase alone or take into consideration the numerous "Keyword Ideas" numbers to determine if a niche could be money maker? I hope I made sense. My exact phrase search gets 2400 global responses but in the area below this on the tool some phrases get responses in the thousands and thousands up to 100k and more for some. Does Global on the KW tool mean US or international?
Also while looking on a Google search for my phrase there appear to be only 25 advertisers for my niche on the right side of the page going 5 search pages deep. This is the advertisers paying for advertising, right? (Adsense? ) Can this be construed as good or bad?
