Banners (can also be referred to as banner ads) are used in advertising web pages to link the advertisement to a certain web page to increase sales. Banner space is sold to other companies as well as used to induce website visitors to consider specific products within the site.

Banners placements on sample websites

A central ad server is used for the delivery of the ads Every time a user clicks on a banner the advertiser will owe the content creator for the interest that the ad has gained. Each user that clicks on a banner brings a nominal fee, usually around ten cents, but they accrue over a set period of time where they are then paid out.

The function of the banner is the same as traditional advertisements but to the online market.
