Does Kestryl replace proof-of-play or delivery verification?

No. Delivery verification confirms whether advertising ran as planned. Kestryl assesses a different part of the campaign: the physical visibility of the panel itself. The two products are complementary.

Does Kestryl prove that people looked at the advertisement?

No. Kestryl does not measure human attention, audience exposure or campaign effectiveness. It measures physical visibility conditions around the panel, including material obstruction of the sightline.

When should we run a Campaign Check?

Ideally before the final panel list is approved. Kestryl can also support pre-launch assurance, or investigate a physical visibility concern during a live campaign.

What do you need from us?

A panel list with locations or owner panel IDs. Campaign dates help Kestryl assess the relevant survey and forecast period. You do not need to provide media rates, booking-system access or revenue data.

What does each panel receive?

Each reviewed result includes a campaign decision (Keep, Review or Replace), the physical obstruction result, survey date, evidence quality, cause of obstruction where identified, forecast risk where supported, and a recommended next step.

What happens when a panel is flagged?

Kestryl provides evidence to support a conversation with the media owner, a request for current site information, or consideration of alternative inventory. Kestryl does not determine contractual remedies or make-good entitlement.

How current is the result?

Every Kestryl result carries a survey date and evidence status. Where a current survey is not available, the panel is identified as requiring new evidence rather than being presented as current.

Is Kestryl only for vegetation?

Vegetation obstruction is Kestryl's first focus because tree growth can materially change a roadside sightline over time. The broader product direction is physical visibility verification across OOH inventory.

For agencies & advertisers

The industry sells billboards nobody can see.

Kestryl checks the physical sightline to every booked panel, before booking or while there is still time to act.

Complementary verification

Delivery verification asks whether the ad ran. Kestryl asks whether the physical asset was visible.

These are different questions, and strong OOH assurance can include both. Delivery verification provides confidence that the campaign was delivered as planned. Kestryl assesses the physical condition of the sightline around the panel. Together, they provide a more complete view of the campaign.

The purpose is not to create conflict between buyers and owners. It is to give both sides a clearer, shared record of the physical asset.
