Microsoft Advertising has introduced a new Search/Shopping filter on the Competition tab. This enhancement enables advertisers to view competitive performance metrics specifically for search ads and shopping ads at both the account level and within Performance Max campaigns.
This is significant as it provides a distinct view of performance across Search and Shopping ads, allowing advertisers to strategically analyze and optimize their campaigns based on more granular data insights. Prior to this update, such specific differentiation wasn’t available through Microsoft Advertising’s utility.
