I just went through the Adwords TNT course, they suggest for a compaign that is not a nich or local, you have to spend at least $500 a month in order to make any profitable return on your advertising labors. They also mentioned that goog price penalizes compaigns running for less than 2 months. Are these indeed factors effecting the cpc?
I have seen discussions of target page/site quality effecting cpc, apparent goog wants to encourage quality user experience even when you've paid for them, perhaps the ultimate factor they should track is the conversion rate, buying what they were searching for seems like the ultimate sign of satisfaction.
