The benefit here for AdWords API users is that AgeRange and Gender criteria will be allowed in Search campaigns. Formerly, you would receive a
CriterionError.CANNOT_ADD_CRITERION_TO_SEARCH_PLUS_CAMPAIGNSerror when trying to add these types.
If your application does any type of automatic bidding, make sure that you update your app to accommodate these new potential bid modifiers on Search campaigns before September 19. These new criteria may be added by users of the AdWords user interface, so your code may have to handle them even if your application doesn't add them explicitly. This may be particularly relevant if you use the "Target and bid" (
targetAll=false) option in TargetingSettingDetail, because the new criteria will begin restricting targeting.
If you have any questions about this change, or other questions about the AdWords API, contact us via the forum.
