This page compiles published data on AI in marketing measurement, drawing on 2026 research from Improvado, Digital Applied (140+ attribution data points across 1,200+ B2B teams), RevSure, and Gartner.
The AI Behavior Index is the research arm of OneChat AI, an integrated multi-model AI platform. We compile and analyze data from primary research sources to make AI adoption and market trends more accessible to journalists, researchers, and decision-makers.
Why attribution adoption and accuracy figures seem to conflict: they measure different things — adoption (how many teams use multi-touch attribution, ~41%) is not accuracy (how many rate it reliable, ~18%). A model can be widely deployed and widely distrusted at the same time, which is exactly the 2026 pattern. Ranges across sources reflect different samples (B2B vs. all marketers, enterprise vs. SMB).
Methodology notes: each chart cites its source. Adoption and accuracy figures come from practitioner surveys with self-reported ratings. The 2028 projection is a forecast. The “triad” framing (MTA + MMM + incrementality) is the widely-reported emerging norm rather than a single measured statistic; the unified-measurement adoption figure (~18%) is from one analytics-trends study.
