Suppose I am using Google to find a good keyword with low competition, so I search "keyword1 keyword2 keyword3" (that's three words with quotes) and I see very low competition, great. Now I go check to see how many advertisers there are for this keyword so I search "keyword1 keyword2 keyword3" on SpyFu and I get nothing, I try "keyword1", "keyword2", "keyword3" seperately and there are some advertisers with decent PPC. So the question is if I SEO optimise a site/page for "keyword1 keyword2 keyword3" can I expect to have individual Adsense ads for "keyword1", "keyword2", "keyword3"? BTW, how should I check how many people search that term in a day? Thanks in advance.
spyfu is not official and the data are based on a crawl of the google results.. to better know whos bidding on the keywords just try to search them in google and look at the right column..
I did that (searched "keyword1 keyword2 keyword3") and there are some google ads there, still doesn't answer my question though.
