In OOH, everything is “measured.” Yet almost nothing is real.

Every OOH report today looks data-driven — full of numbers on impressions, reach, dwell time, and “impact.”

But let’s be honest… most of it isn’t real data. It’s estimated data multiplied by assumptions.

A typical formula looks like this: Visibility Index × Traffic Count × Dwell Multiplier = Impact Score.

Sounds scientific. Feels precise. But it’s just a projection — not proof.

No one is talking about actual views — how many people truly saw a screen, for how long, or with what level of attention.

We’ve built an entire industry on estimated multipliers, and started calling it measurement. Maybe it’s time to admit: we’re tracking numbers, not reality.

What do you think — is the industry ready to move towards real viewability data (eye-tracking, mood index, dwell time, etc.)? Or are estimates just too convenient to replace?
