Hi, I'm sorry if this has been posted but I couldnt find exactly what I needed. Can anyone point me somewhere to learn how to tweak for AdSense ads. Specifically, I have a site geared towards a particular city. So my big keywords combo is "<cityname> <subject>". AdSense is sending me almost exclusively ads for the <subject> but I'd prefer mostly ads for <cityname>. Any help would be greatly appreciated.
