Billboard Advertising is a tall and narrow banner advertisement usually placed to the right of content on a Web page. Our standard dimensions for a billboard ad 250x 350 pixels. Like another popular type of Internet ad, the leaderboard, the billboard offers an advertiser a large space for a message. Unlike the leaderboard, which is usually placed between the masthead (title area of a Web page) and the page’s content, a billboard remains at least partly visible as the viewer scrolls down the page.
