What is the price metric of the DOOH screen advertising inventory?

DOOH Screen Advertising refers to digital advertising displayed on electronic screens located in public spaces and high-traffic areas. This form of advertising merges the traditional impact of outdoor advertising with the dynamic capabilities of digital media. Here’s a detailed overview:

Generally, the DOOH screens are lent in three price metrics:

The Cost Per Thousand Impressions model or CPM: Advertisers charge a rate for every 1000 brand impressions that the DOOH screen will register. Usually, unlike digital ads on devices, a single digital ad played on a digital screen gains more than one view per play. So, multiple brand impressions per ad play ensure that the 1000 ad impressions are reached by less than 1000 ad plays.
Buying a proportion of the total ad inventory of a DOOH screen: Ad buyers also wish to buy a specific proportion of the daily ad coverage of a DOOH screen or multiple DOOH screens of a network or an area.

Playing brand ads on a loop: Brand content and ads play repeatedly after a said amount of time on a DOOH screen advertising. Thus, the same content is played in a recurring fashion for ‘n’ number of times a day in a loop. So, to register more brand impressions, ad buyers or ad agencies buy several ad slots in a single loop.
