Web banner
A form of online advertising that entails emebedding an advertisement into a web page that is intended to attract a web surfer to a commercial website. The advertisement is constructed from an image (GIF, JPEG), JavaScript program or multimedia object employing technologies such as Java, Shockwave or Flash, often employing animation or sound to maximize presence.
The web banner is displayed when a web page that references the banner is loaded into a web browser. This event is known as an "impression". When the viewer clicks on the banner, the viewer is directed to the website advertised in the banner. This event is known as a "click through".
Web banners function the same way as traditional advertisements are intended to function: notifying consumers of the product or service and presenting reasons why the consumer should choose the product in question, although web banners differ in that the results for advertisment campaigns may be monitored real-time and may be targeted to the viewer's interests.
