What is Banner Advertising?
Banner advertising are the small rectangular advertisements appear on all sorts of Web pages and vary considerably in appearance and subject matter, but they all share a basic function: “if you click on them, your Internet browser will take you to the advertiser’s Web site.”
A bit of HTML code instructs a Web server to bring up a particular Web page when a user clicks on a certain piece of text. Banner ads are essentially the same thing, except that instead of text, the link is displayed as a box containing graphics (usually with textual elements) and sometimes animation.
