Sources & method
Every price and statistic on this site carries an evidence level so you know how much weight it holds. We do not sell ad space, so we have no reason to inflate a number.
How to read our evidence levels
verified Primary source, confirmed directly (a regulator, a network operator, an industry measurement body). 6 sources.
reported A reputable secondary source reporting primary data (trade press, measurement vendors). 4 sources.
estimate An industry range from vendor rate cards or guides. Directional, not a quote. Treat as a starting point. 1 sources.
The figure that drives this site
Vendors quote impressions. Independent funnel data shows only 0.4 to 2% of those impressions become brand recall (Digital Signage Today, Geopath). That gap is why we report cost-per-memory next to CPM, and why our Cost & Real-Reach Estimator exists.
