Since February 2013 advertisers have been able to
explicitly set the Content Bid Dimension in the API. In the meantime, we’ve also been automatically setting the Content Bid Dimension for advertisers using older versions of the API, and for those using v201302 that did not explicitly specify a bid dimension. The automatic setting followed the logic described in this
blog post.
Once v201209 is deprecated and all legacy campaigns are auto-migrated to Enhanced Campaigns and Powerful Bidding (July 22, 2013), we’ll stop setting the Content Bid Dimension implicitly for ad groups (new and existing). As announced back in March, advertisers wanting to override the ad group default bid with criteria-level bids from a given content dimension will need to explicitly set the
contentBidCriterionTypeGroup to the desired
CriterionTypeGroup.
Existing ad groups will keep their Content Bid Dimension setting, regardless of whether it has been set implicitly or explicitly. No changes are needed if you want to preserve the same Content Bid Dimension. After July 22, if you create a new ad group or want to change the bid dimension of an existing one, you’ll have to explicitly set the Content Bid Dimension.
You can verify the content bid dimension using
AdGroupService.AdGroup#contentBidCriterionTypeGroup
