| ˈba-nər ˈad |
A web banner or a banner ad is a type of graphical advertisement that is displayed on a host site. Banner ads can be of different sizes and shapes, but are usually left-to-right and across the top of a host site (referred to as a leaderboard) or up-and-down and to the side (called a skyscraper). Banner ads also function as hyperlinks pointing to the advertiser’s website. The host is paid for allowing the banner ad to be displayed on their site. An advertiser may find a group of willing hosts on an ad network or platform like AdSense.
