Bannering

Banners are placed on other sites to attract their visitors to your website or vice versa. By clicking the banner the surfer is lead through a link to the website of the advertiser.

The banner can contain an image (gif, jpeg, png), javascript program or multimedia object employing technologies such as java, shockwave or flash, often employing animation, sound, or video 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.

Banners are usually placed on web pages that have interesting content or content that is similar to your sites content.

Banner advertising is often paid advertising and the price of a campaign is mostly set by one of these two business models:
- cost per impression (CPI), for every banner that is shown to a visitor money is paid by the advertiser
- cost per click (CPC), for every unique visitor clicking the banner money is paid by the advertiser

Sometimes advertisers use ad networks to serve their advertisements, resulting in a revenue share system. These systems are mostly not highly targeted and therefor generating less clicks and conversions than personalized bannering campaigns.
