Which advertising method includes placements such as bus ads and billboards?

Outdoor advertising encompasses any promotional material displayed outside of a building or structure, targeting consumers in public spaces. This category includes placement opportunities such as billboards, bus ads, transit ads, and other forms of media that utilize physical locations to convey messages to pedestrians and vehicular traffic.

This method is effective in reaching a broad audience and enhancing brand visibility in high-traffic areas. Outdoor advertising is particularly beneficial for brand awareness, as it can capture the attention of a diverse demographic, particularly in urban settings. By leveraging high-visibility spaces, brands can make significant impressions on potential customers as they go about their daily routines.

In contrast, other advertising methods like direct marketing focus on personalized communication directly to the consumer's address or email, print advertising usually refers to media in printed formats such as newspapers and magazines, and referral marketing is based on encouraging existing customers to refer new clients. These methods serve different purposes and utilize various channels rather than the large-scale, public-facing approach characteristic of outdoor advertising.
