Programmatic DOOH Buying on Vistar, Hivestack and VIOOH

Every impression we are invoiced for is reconciled against the panel-level proof-of-play file: screen ID, timestamp, loop position, creative served. On the campaigns we have taken over from other buyers, between 4 and 9 percent of delivered impressions failed that check, either panels playing outside the daypart written on the insertion order or filling a loop slot that was not the one sold. The reconciliation is the work. The buying is the easier half. Supply we transact on: Vistar Media and Hivestack as the primary demand paths, VIOOH and Broadsign Reach where a network's inventory sits there exclusively, Place Exchange for parts of the US venue estate. Deals are struck as private marketplaces with named venue lists and OpenOOH venue taxonomy codes written into the deal, never as a marketplace-wide category. In the Czech market that means panel lists we can name across the JCDecaux and BigBoard digital estates, retail and transport, rather than a country line item. Audience multipliers: A DOOH impression is a play multiplied by an audience estimate. Where the supplier can show the source of that estimate, a mobility panel, a counted footfall series, a transport operator's own passenger data, we buy on the audience CPM. Where they cannot, we buy on plays and apply our own multiplier, and the report says which of the two produced the number. We have not accepted a multiplier we could not trace to a named provider, and this is the most common reason our delivered impression counts come in under the plan a network would sell you directly. Conditional playout: Worth building only when the condition changes the message. Temperature and pollen thresholds for a health advertiser, kick-off and full-time for sport, open-house hours for a residential developer. We build these as data-driven creative rules in the DSP with a fallback frame, and we test the fallback, because a dead feed at 07:00 on a Saturday is how a screen ends up serving nothing in the middle of the loop. Reporting: Panel-level delivery, loop share by hour, and the reconciliation write-off, delivered as a file you can query rather than a slide. We do not put DOOH impressions into the same attribution table as your paid search conversions. Whatever a last-click model assigns to a screen is an artefact, and setting the two side by side in one grid invites a budget decision the data cannot support. Screen effect is read on geography and time, which is what the holdout exists for. Not included: Classic static OOH negotiation and print production. Creative origination for full-motion frames. We adapt, storyboard and write the specification, and we will bring in a production partner, but we do not run an edit suite. Cinema. Any network that will not release play logs, whatever the CPM. Who this is not for: Advertisers who want national coverage at the lowest available CPM. That buy exists, the networks sell it directly, and we would add cost without adding much judgement. Also not for anyone whose plan depends on a screen driving a same-day click. Fees and media: Package prices are our fee. Media runs on your DSP seat where you have one, or ours at cost with platform invoices passed through. Under roughly 30,000 euro of DOOH media per flight there is not enough panel-level variance for this level of scrutiny to pay for itself, and we will tell you that before you sign rather than after.
