The more niche you are, the more effective Adwords will be. High volume/low margin rarely makes sense on Adwords, because you'll face death by a thousand cuts by people who can target better, make bigger margins, bid higher and get better QS.
For businesses that can best exploit Adwords targeting, it can be breathtakingly effective. I've dealt with specialist contractors who saw 25000% ROI on their Adwords spend. Search terms like "loan consolidation" and "car insurance" cost tens of dollars per click and are absolutely worth that much.
