Google Ads has expanded Smart Bidding Exploration to include Performance Max and Shopping campaigns, in addition to the existing support for Search campaigns. Advertisers can now use Target ROAS across these campaign types.
Two new help pages outline the functionality. Smart Bidding Exploration for Performance Max aims to maximize performance on the search channel by bidding on additional searches among existing eligible terms. For Shopping campaigns, exploration applies to both Search and Shopping traffic if a Merchant Center feed is present.
Eligible campaigns must use Target ROAS bidding and should not be limited by budget. Portfolio bid strategies are only compatible with Search campaigns, and Smart Bidding Exploration is not available in Search Ads 360 for Shopping or retail Performance Max campaigns.
