Outdoor has historically been the hardest channel to audit: you pay for a board or a package, receive installation photography, and trust traffic models for the rest. Moving LED on taxis and delivery bikes changes the conversation because plays can be tied to time, route, and device, closer to how digital reports impressions.
Proof-of-play vs proof-of-posting
Proof-of-posting shows that a unit existed and a creative was mounted, important, but silent on whether your ad actually ran on schedule. Proof-of-play confirms that scheduled loops fired while the vehicle was on route during your booked window. For procurement teams under scrutiny, that distinction is the difference between “we bought media” and “we can show delivery.”
What Admobi logs on a typical flight
During a booked window, plays are associated with GPS traces from equipped units. Summaries align to your campaign dates, corridors, and time bands, not a single hero photo at one junction. You still get operational visibility (creative live, QA passed); the log is what you attach when finance asks whether the flight delivered.
Who benefits inside your organisation
Brand managers get confidence to shift budget mid-flight if a corridor under-delivers. Agencies can report to clients without defending modeled reach alone. Finance and procurement get artefacts that resemble digital delivery reports. Legal and compliance teams see timestamped evidence when claims or public-interest messaging must be demonstrable.
Limits to set expectations fairly
GPS proof describes delivery on moving inventory, not individual viewer attention. Weather, traffic incidents, and temporary road closures can reduce impressions on a given day without voiding the entire flight, we work with you on make-goods per contract. Proof complements creative strength; it does not replace it.
How to request proof in your brief
Ask for corridor-level summaries in your preferred format (CSV or PDF) and name the stakeholder who should receive them. If you need weekly splits for a multi-week book, say so up front so reporting is configured before day one.
