Depending on how it’s used, a banner is either a graphic image that announces the name or identity of a site (and often is spread across the width of the Web page) or is an advertising image. Advertisers sometimes count banner “views,” or the number of times a banner graphic image was downloaded over a period of time.
Most of the time, a banner (in graphic or photo format) is found at the top of a web page. The term banner is also used to identify companies or products presented at exhibition booths (in the form of a roll-up). The term banner is also used in promotion and marketing to advertise products or services in public places (stadiums, stations, airports, along avenues, etc.)
