Marketing mix modeling
BuiltThe client. A multi-brand advertiser refreshes its MMM quarterly through an agency. Every refresh starts with weeks of input wrangling: spend that doesn't reconcile to finance, a channel that went dark, a tracking change nobody logged.
- Define the inputs once. National, attributed and geo datasets live in the data model. An agent writes the spec; a data admin merges it.
- Validate every week. Coverage gaps, missing weeks, cost jumps, level shifts, the attribution identity, reconciliation and a sanity forecast.
- Predict every gap. Missing weeks, late feeds and channels that went dark get a forecast fill, clearly flagged and replaced when actuals arrive, so the model never runs on holes.
- Explain every dip and spike in the workbench, drilled down to the creative, with the cause logged.
- Publish and sign off a version: frozen, exported to the modelers or agency, compared with the last one.
- Ask anything about it. “Why is TikTok down in September?” is answered against the same governed data.
