What is a banner Exchange?
The typical web banner is sized 468×60 pixels. 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”. In many cases, banners are delivered by a central ad server.
Many banner ads work on a click-through payback system. When the advertiser scans their logfiles and detects that a web user has visited the advertiser’s site from the content site by clicking on the banner ad, the advertiser sends the content provider some small amount of money (usually around five to ten US cents). This payback system is often how the content provider is able to pay for the internet access to supply the content in the first place.
Web banner exchanges 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 advertisement campaigns may be monitored real-time and may be targeted to the viewer’s interests.
Many web surfers regard these advertisements as highly annoying because they distract from a web page’s actual content or waste bandwidth. Newer web browsers often include options to disable pop-ups or block images from selected websites.
The Interactive Advertising Bureau has released a set of sizes which it has designed to make ad sizing more predictable and better for both consumer and producer. It calls these web advertisements “interactive marketing units”. Most used sizes are as follows (measurements in pixels width/height):
- Full Banner: 468 by 60
- Half Banner: 234 by 60
- Micro Bar: 88 by 31
- Button 1: 120 by 90
- Button 2: 120 by 60
- Vertical Banner: 120 by 240
- Square Button: 125 square
- Skyscraper: 120 by 600
A classic one.
