A web banner or banner ad is a form of
advertising on the
World Wide Web. This form of online advertising entails embedding an advertisement into a
web page. It is intended to attract
traffic to a
website by linking them to the
web site of the advertiser. The advertisement is constructed from an image (
GIF,
JPEG,
PNG),
JavaScript program or multimedia object employing technologies such as
Java,
Shockwave or
Flash, often employing animation or sound to maximize presence. Images are usually in a high-aspect ratio shape (i.e. either wide and short, or tall and narrow) hence the reference to
banners. These images are usually placed on web pages that have interesting content, such as a newspaper article or an opinion piece.
