Ok I know, many times on this forum we have discussed things such as Adsense, and using programs like kontera, intellitxt.. etc... etc. And yeah it is against Google TOS as far as the replies here are concerned. I was just wondering contextual is.. reading the whole text and then deciding on the text.. its not just plain keyword targetting.. Programs like Kontera, intellitxt... they just target keywords.. so how does that work? Coz in the end.. google program says... that the ad's in its content network.. are smartpriced.. on the basis of the context.. and not just keyword.
