Within the Performance Center of Search Ads 360, what should you set up if you have a specific amount of money to spend on a campaign and you hope to get a decent return on investment (ROI)?

A Budget bid strategy in Search Ads 360's Performance Center is designed for situations where you have a fixed budget and want to maximize ROI. It helps you allocate your budget effectively across campaigns to achieve your spending goals while optimizing for conversions. Data-driven attribution is a reporting model, not a bidding strategy. Google Ads auction-time bidding is a feature of Google Ads, but "Budget bid strategy" specifically refers to the Search Ads 360 tool for managing spend against a target. Conversion cart data provides additional detail about conversions but isn't a bidding strategy itself.
