Frustration With Google AdWords
In normal markets, I would be strongly tempted to take my business to vibrant competitive offerings. Sadly, Google is pretty much the only game in town for viable CPC advertising: even if Microsoft/Yahoo exorcized the abominations haunting their UIs, they would not have enough inventory to matter for me in my niche (I’ve tried before).
I tried Yahoo a while ago and was appalled at how little inventory they had. I think it took almost a year for them to spend whatever the minimum payment was. On the other hand, Google’s system encourages you to overpay for keywords that no one else wants.
