Hi. Can anybody tell me about how to minimise adwords cost to get maximum clicks and maximise adsense revenue. My adwords campaign is running with high cost but adsense revenue is not up to the mark.
It's a deliberate google policy to price arbitrage out http://forums.digitalpoint.com/showthread.php?t=1273445
Yeah, about 2 years ago this practice of arbitrage died away. Few people do this anymore. I think that WiseGeek was the last to go, and now they don't do PPC anymore. I suppose these "info directory" things are doing arbitrage, though.
