Unified Measurement Architecture
also: UMM · triangulation · MMM plus MTA plus experimentation
Definition
A Unified Measurement Architecture combines Marketing Mix Modeling, Multi-Touch Attribution, and randomized incrementality experiments into a single decision stack, with each method calibrated against the others. MMM supplies top-down causal anchors, MTA supplies in-flight optimization, experiments supply the ground truth.
No single attribution method is sufficient in the post-cookie era. Unified Measurement triangulates: geo-lift and conversion-lift experiments produce unbiased causal estimates on specific campaigns, MMM provides channel-level elasticities at scale, and MTA enables within-session tactical decisions. The critical practice is calibration: experimental lift scales MMM priors, MMM scales MTA credit, experiments re-validate periodically. Without triangulation, each method's biases accumulate silently.

Creative Fatigue Detection Using Entropy Metrics: An Automated Framework for Ad Refresh Cycles
By the time your dashboard shows declining CTR, creative fatigue has already cost you weeks of wasted spend. Shannon entropy applied to engagement signals detects fatigue 11 days earlier than traditional frequency caps.

Marketing Mix Modeling in the Privacy-First Era: Bayesian Structural Time Series Without User-Level Data
Cookies are dying. Deterministic attribution is shrinking. The irony: the measurement approach from the 1960s — Marketing Mix Modeling — is making a comeback, now powered by Bayesian inference that would have been computationally impossible when it was first invented.

Unified Measurement Architecture: Connecting MMM, MTA, and Experimentation Into a Single Source of Truth
MMM says Facebook works. MTA says Google works. The incrementality test says neither works as well as you thought. Three measurement systems, three different answers — here's how to reconcile them into one coherent picture.
