For advertisers · measurement & proof

Most platforms show you numbers. We show you how they're counted.

Four numbers run a campaign report, and each one arrives with the class it was produced under: deterministic, modelled or statistical.

How we count

The four numbers, and where each one comes from.

NumberHow it's producedClass
PlaysConfirmed by the device, sealed in a tamper-evident ledger, MRC-aligned; invalid traffic filtered and disclosedDeterministic
ImpressionsPlays × audience model on the IAB DOOH framework; evidence grade published per venue; methodology versioned, corrections loggedModelled — disclosed
Attributed salesSKU-matched till data where the loop closes at the counterDeterministic

Every campaign report carries the same grades, and a number we can't source is labelled as modelled.

The classes

Three grades, applied the same way every time.

01

Deterministic

Counted from a device or a till feed. The event happened and the platform holds the record of it.

02

Modelled

Produced by a published model. Every factor in the chain is graded measured, audited or assumed, and the model is versioned.

03

Statistical

Read from a study design — exposed stores against matched control stores — and the design is disclosed with the result.

The grades in the product

Each factor behind an impression states its basis.

An impression is a chain of factors: transactions in the hour, party size, conversion rate, exposure window, visibility. The platform labels each one measured, audited or assumed before it multiplies them.

The grading system running in the product — every factor labelled MEASURED or ASSUMED.

The methodology

The method ships inside the platform.

Buyers read what counts as a play, how plays become impressions, and which defaults are assumed — on the same screen the numbers came from. Corrections are logged where they happened.

Proof

Read a real report before you buy anything.

We'll send a sample campaign report with the grades and the study design left in.
