Google AdWords Plans Migration To 'Optimize For Conversions,' February 2012 [adwords.blogspot.com]
If you’re focused on conversions and CPA (cost-per-acquisition), you may already be using Conversion Optimizer or Enhanced CPC to optimize your campaigns to get you more conversions at a lower cost. To ensure that your campaign settings are also in line with your conversion goals, we plan to migrate existing campaigns using Conversion Optimizer or Enhanced CPC with “Optimize for clicks” ad rotation to “Optimize for conversions” ad rotation. Our studies have shown that campaigns moving from “Optimize for clicks” to “Optimize for conversions” see a 5% increase in conversions on average. This migration is scheduled for February 2012.
