In short
Data Strength is Google’s framework for how ready an advertiser’s first-party data is to power AI-driven campaigns. It progresses through four steps: connect your data sources, maximize your signals, activate Google AI, and prove ROI. Google positions Data Strength as the foundation that decides how well Smart Bidding and Performance Max can learn, because AI-driven bidding is only as good as the signal it is trained on. The reason the term is spreading is that Google Marketing Live 2026 tied budget-deciding models, including Qualified Future Conversions, directly to signal quality, so weak data now compounds into weak delivery rather than being a minor reporting gap. Datahash is named by Google among the partners that enable Data Strength and is integrated with the Data Manager API, which places it on the connect-and-maximize steps where most advertisers lose signal. Data Strength is best read as a maturity model: it names where an advertiser sits and what the next step is.

What do the four Data Strength steps look like in practice?
