A DOOH publisher logs a play event — creative X ran on screen Y at time Z. Who saw it is inferred. The standard approach uses mobile location data: opt-in location signals from mobile devices to estimate how many people were present near a screen during a play window. That audience estimate is then matched to demographic profiles or used as a proxy for impression delivery. The measurement is probabilistic at every step, and most vendors present the output with more precision than the underlying methodology supports.
Programmatic DOOH has added digital-style buying infrastructure — real-time bidding, audience targeting, campaign management — without adding digital-style measurement. You can buy a DOOH impression with the precision of a display ad. You cannot measure its effect with the same precision. Recognizing this gap before the campaign runs, rather than after, is what separates a defensible DOOH program from an expensive one.
pDOOH promises digital targeting with OOH scale. The buying infrastructure delivers on targeting. The measurement infrastructure is still OOH-grade — location data accuracy, dwell time estimation, and attribution to conversion are all modeled, not measured.
A 50-meter accuracy radius at a dense urban billboard means a location signal could be attributed to dozens of nearby businesses. The accuracy assumptions baked into DOOH audience estimates are rarely disclosed and almost never audited.
If your multi-channel program includes DOOH, it needs to be treated as a separate probabilistic analysis — not joined with deterministic impression data from digital channels. Mixing methodologies corrupts both.
