Outdoor advertising refers to promotional messages displayed in public spaces to reach a wide audience. Common formats include billboards, posters, and transit ads found on buses and subways. This type of advertising is designed to capture the attention of people while they are on the move, making it an effective way to increase brand visibility. The effectiveness of outdoor advertising relies on its strategic placement in high-traffic areas, such as city streets and shopping centers. Advertisers often use bold visuals and concise messages to convey their brand's message quickly. This method complements other advertising channels, such as television and online marketing, to create a comprehensive marketing strategy.
