A billboard is a large outdoor advertising structure typically found in high-traffic areas such as highways, urban centers, and commercial districts. It is designed to capture the attention of drivers and pedestrians with its bold and eye-catching graphics, images, and messages. Billboards come in various sizes and types, including digital billboards that use LED screens to display dynamic and interactive content. Advertisers use billboards to promote their products, services, or brands to a wide audience and create brand awareness. The effectiveness of billboards is measured in terms of impressions, or the number of people who see the advertisement.
