How to Display Targeted Advertisements
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
You can target advertisements through page group or user profiles. This topic demonstrates how to target users based on a page group.
To display targeted advertisements
Create a TargetingContextProfile. Specify the PageGroup ad that you want.
Create a ContentSelector object and set its properties.
Set the ad Size.
Use GetContent to retrieve ad content.
Bind the results to a repeater.
Dump out trace messages.
Example
The following code creates a targeting profile, a user profile, runs the ContentSelector object, and displays targeted advertisements on an ASP.NET Web form.
TargetedAd.aspx
