Starting on March 15th, the bid strategy for audience campaigns can only be set at the campaign level. An audience campaign’s bid strategy will be in effect for all of its ad groups. Attempts to set the ad group level bid strategy with the Bing Ads API will be silently ignored and no error will be returned.
The bid strategy option to select either Use the campaign’s bid strategy or Use the bid I set for an ad group is being removed from Microsoft Advertising. Whether you previously chose Use the campaign’s bid strategy or Use the bid I set for an ad group, all ad groups will use the campaign’s bid strategy.
This change does not affect bids in any way, since at this point audience campaigns only support the manual CPC bid strategy.
Audience campaigns will continue to support manual CPC as a campaign level bid strategy. Only search and shopping campaigns will deprecate manual CPC as a bid strategy as announced in the previous blog post.
As always please feel free to contact support or post a question in the Bing Ads API developer forum.
