What Is OOH Advertising?

Out-of-home advertising refers to any advertising that reaches the consumer while they are outside their homes. This includes traditional billboards, transit ads, or street furniture, and locations like malls, airports, and stadiums. With digital technology, OOH now also includes Digital OOH (DOOH) formats such as LED screens and programmatic ads that can be dynamically changed in real time.

OOH captures attention in high-traffic areas, delivering impactful visuals to commuters, shoppers, and travelers at key moments of their daily journeys.

Types of OOH Advertising

OOH advertising comes in various formats, giving brands the flexibility to choose based on location, audience, and budget. Common types include:

Brands can now capture their audience's attention on the go through transit advertising—reaching commuters on the move through buses, taxis, subways, and trains.

Find the right customers at the right place and increase sales by igniting the impulse purchases through POS display ads located near checkout areas in retail spaces.

  • Place-Based Media

These can help in creating meaningful interactions with consumers on airports, gyms, malls, cinemas, and other venues with steady footfall.
