Ad Rotator Component

The Ad Rotator component creates an Ad Rotator object that automates the rotation of advertisement images on a Web page. Each time a user opens or reloads the Web page, the Ad Rotator component displays a new advertisement based on the information you specify in a Rotator Schedule File.

You can record how many users click each advertisement by setting the URL parameter in the Rotator Schedule file to direct users to the Redirection File. When you specify this parameter, each jump to an advertiser's URL is recorded in the Web server activity logs. For more information on activity logs, see Logging Web Site Activity.
