Google outlines a three-part framework for evaluating campaign performance

The Google Ads & Commerce Blog published an Ads Decoded episode titled “Build a measurement stack you can rely on to steer your campaigns” on September 2, 2026.

The episode discusses three ways to assess marketing campaigns: attribution, incrementality, and media mix models.

The retained evidence is limited to the source title and summary; no source body, quotation, methodology, or implementation detail is available.

For merchants reviewing campaign performance, the episode signals that a measurement stack can involve more than a single attribution view.

Attribution, incrementality, and media mix models describe different measurement approaches, so teams may need to clarify which business question each approach is intended to answer.

The available evidence does not establish that Google is announcing a new product, policy, or required workflow, so merchants should treat this as measurement guidance rather than a platform change.
