Google Migrating AdWords Users To "Optimize For Conversions"

Google released information that from February 2012, they’ll migrate all  Conversion Optimizer & Enhanced CPC campaigns to “Optimize for conversions” unless otherwise requested.

If you don’t want to have your campaigns migrated, then tell Google by the end of January using this form.

According to Google it will lead to about 5% increases in conversion volume on average across all advertisers who switch.

Google added:

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.
