So I understand conceptually how you're supposed to group about 5-10 related keywords per ad group in Adwords when you're running PPC campaigns, or else Google won't give you very many impressions.
But my question is, what if you want to use a relatively large list of say 500 long tail keywords? How do you group your keywords then?
