Google essentially lowers the amount of available inventory for ads by demoting publishers. Therefore raising the CPC amounts that advertisers pay, creating a win, win scenario.
That is an interesting scenario, a question perhaps best addressed to the AdWords crowd. I hope you (the OP) don't mind but I posed the question in a new discussion [webmasterworld.com] in the AdWords forum. I really am curious if there is or is not an uptick in AdWords competition following a Google Search update.
