So far the discussion has not touched on what is huge about this change. If I am reading this correctly (always an "if") then Google is moving their Adword product in a new direction here -- it is not a PPC model at all. It is a PPI model -- "Pay Per Impressions," in this case, based on CPM. (Minimum $2 cpm bid, at least in the test I set up). So -- you pay let's say $2 for 1000 impressions -- you may get NO clicks! This is the closest thing to the model of television spots. You pay x amount for so many eyeballs. No clicks guaranteed. Adwords is no longer a pure PPC model. It's a PPC/PPI model.
Unless I'm missing something.
