What Are Targeting Expressions?
Targeting expressions are a type of expression that targets a campaign item based on profile properties. Commerce Server Core Systems supports user profiles and context profiles.
To target users on your site, you use user profiles. For example, "If User is female and UserAge is greater than 40, then deliver ad for blue paint."
You use context profiles to target information that represents the context of a request for content. You can also target content to specific sections of a Web site, called page groups. For example, you can create a target expression that will display certain ads only on sports pages.
Marketing target expressions are evaluated by the MarketingExpressionEvaluator object.
