Proof of Posting vs Proof of Execution in OOH

Both terms matter in outdoor advertising reporting, but they are not the same.

What Proof of Posting Means

Proof of posting usually confirms that a creative has been installed at a specific site. In traditional workflows, this proof may be a photo shared by a vendor or field agent.

The weakness is that a simple photo may not prove the correct location, date, creative condition, or campaign duration.

What Proof of Execution Means

Proof of execution is a more complete delivery record. It can include GPS coordinates, timestamped photos, site IDs, campaign dates, creative compliance, exception history, and final reporting.

For brands and agencies, proof of execution is stronger because it supports billing, client review, and vendor accountability.

How GeoProof Improves Both

GeoProof captures proof of posting as part of a larger proof-of-execution workflow. The platform ties proof to the booked site, field agent, vendor, campaign, and report so teams can trust the final delivery record.

Proof Terminology FAQ

Proof of posting is evidence that an ad creative was posted or installed at a site, often using a photo and basic site details.
Proof of execution is broader evidence that the campaign was delivered as agreed, including installation, location, timing, compliance, and final reporting.
Agencies should share proof of execution whenever possible because it gives a more complete and defensible view of campaign delivery.
