Marketing Mix Modeling (MMM)

A model that measures what each channel actually contributed to revenue — including the offline ones and the ones no pixel can see — and turns that into a budget recommendation with honest intervals.

Who it is for

CMOs and growth leads spending meaningfully across several channels, where last-click attribution has stopped matching what the business feels.

Short answer

A Bayesian model attributes revenue across every channel you spend on, accounting for the lag between spend and sale, diminishing returns at high spend, seasonality, price and promotions. It works from aggregate spend and revenue rather than user-level tracking, so it survives cookie loss and covers TV, print and sponsorships. The output is a contribution estimate per channel with a credible interval, and a budget scenario tool.

The problem

Last-click gives all the credit to the final ad, and the whole budget slowly migrates to the bottom of the funnel.

01

Platforms all claim the same sale

Add up the conversions each platform reports and you get more revenue than the company earned. Every dashboard is confident, and together they are arithmetically impossible.

02

Offline and brand spend look free of results

Anything without a click — TV, outdoor, sponsorship, podcasts — shows nothing in the attribution tool. It gets cut first, and the effect shows up as an unexplained dip a quarter later.

03

Nobody knows where saturation starts

Spend doubles on the channel with the best reported ROAS and revenue does not follow. Without a saturation curve, the answer only arrives after the money is spent.

How it works

From trigger to result, step by step.

01

Assemble spend and outcome history

Weekly spend by channel, revenue, price and promotion calendar, distribution changes, seasonality and major external events. Twelve months is the floor, twenty-four is where it becomes reliable.

02

Model adstock and saturation

Each channel gets a lag structure — how long the effect persists — and a diminishing-returns curve. Without both, a model will happily recommend infinite spend on the last thing that worked.

03

Fit with priors, report intervals

A Bayesian fit lets known constraints and prior tests inform the model, and produces a range rather than a single number. A point estimate for TV contribution is false precision, and we do not print one.

04

Validate against reality

The model is checked on a held-out period and, wherever possible, against geo tests or blackout periods you have actually run. Agreement with a real experiment is worth more than a good fit.

05

Give planners a scenario tool

A dashboard where the team shifts budget between channels and sees the modelled revenue effect with its uncertainty. Planning conversations move from opinion to a shared model with visible assumptions.

Honest limits

When this is not the right solution.

·Under a year of history there is not enough variation to separate channels, and the model will confidently attribute noise.
·If you spend on one or two channels only, MMM is overkill — a well-run geo test or holdout answers the question faster and cheaper.
·If spend has been flat for two years, there is nothing to learn from. Some deliberate variation has to exist first, and we will help design it.

Questions we get about this one

Attribution follows individual users and their clicks; MMM works on aggregate spend and revenue over time. It is unaffected by cookie loss and covers offline, which is exactly where attribution is blind.
