As out-of-home advertising continues to scale in complexity and investment, the role of proof and media monitoring has become increasingly central to campaign performance.
Site images are widely used as standard proof in OOH reporting. They confirm site existence and provide accountability.
However, as campaigns continue to evolve across sites, formats, and durations, brands are increasingly looking beyond visual confirmation alone. The emphasis is shifting toward proof that demonstrates on-ground performance, not just presence.
From Proof of Presence to Proof of Performance
OOH campaigns today operate at scale. While traditional site images confirm that billboards were installed, brands now require proof that reflects actual on-ground performance across the campaign duration.
This shift has made geo-tagged, time-stamped evidence essential. It allows brands to verify correct site and creative deployment, visibility from intended traffic viewpoints, illumination quality, and consistency over time and across locations.

Modern proof is expected to be:
- Consistent
- Captured under real operating conditions
- Cover the full campaign period
- Follow a consistent format
When implemented through controlled systems, geo-tagged evidence provides a reliable and auditable foundation for performance verification in OOH campaigns.
Checklist for Proof of Performance
A complete proof-of-performance checklist for OOH campaigns should include:
- Geo-tagged images
Each photo must include GPS coordinates of the approved site.
- Time-stamped evidence
The date and time should fall within the campaign period.
- Correct creative
Approved artwork and branding should be clearly displayed.
- Clear visibility
Media should be fully visible and easy to see from intended viewpoints.
- PAN-India coverage
Photo proofs should cover every approved location across all locations.
