Evidence, Not Anecdotes
What happens when Out of Home locations are measured rather than estimated.
What happens when Out of Home locations are measured rather than estimated.
Case Study
A premium retail destination was trading inventory priced on modelled area estimates. The media owner suspected the numbers understated its real audience — particularly at weekends — but had no location-specific evidence to price against.
JamBox measurement was deployed at the location, with zones configured for the retail environment and data reporting through the Data Jam Portal in real time.
Measured audiences ran far ahead of the estimates. On a single Saturday, JamBox measured 200,990 impressions against 80,000 estimated by traditional methods — 2.5x the modelled figure. Saturdays delivered 74.6% more impressions than Tuesdays, daily averages climbed steadily from Monday (90,459) to Friday (123,354), and Mother's Day weekend ran 50% above a typical Saturday.
With measured data, the media owner could price weekend and event inventory on real delivery rather than a flat estimate, and give advertisers site-level, hour-by-hour proof of performance. The premium the location deserved became visible — and chargeable.
Published Evidence
Every month, Data Jam publishes The Signal — a like-for-like movement intelligence report across hundreds of matched UK locations. It's the same measurement clients use, working in public.
When a reported 1.5 million people came out for Arsenal's Champions Parade, the network measured 5x a normal Sunday all day — peaking at 6.7x as the parade passed.
