> people need to work on their algorithms for sure. Do they? Most adspace buyers are utterly clueless about how Google algorithms work. The flaws the OP describe are real, but my bet is 80 to 90% of adspace buyers have no idea of the shortcomings. Nor do they care BTW: the ROI on their ad dollar when spent on GOOG is so much higher than traditional channels ever were that they just set the drip in place and never look back.
