True Stats.

Opportunity to see (OTS) estimates potential exposure. Weather, traffic, roadworks and local events can change the conditions around a screen.

True Stats explores how to incorporate those conditions into campaign reporting.

Contextual estimates are not a count of people who actually looked at an ad.
