Each time you add a new content targeter, you need to set up the business rules for delivering the selected content to its target audience. For example, you could create a rule that shows content from a folder called Weekend Features to all users every Friday.

A word about targeters and site performance: The ATG Personalization module caches (or temporarily stores) the content that it displays after each targeting operation. This behavior allows it to serve the content much faster to the next visitor who matches the targeting criteria. This caching mechanism will not be effective if your targeting rules include profile or request properties (time of day, for example) that have many possible values for each visitor. For example, if you create a targeter that includes a multi-value property called interests, and there are many possible value combinations for each visitor (“skiing, golf, hockey,” “biking, golf,” “soccer, tennis, swimming,”), it is unlikely that the Personalization module would be able to use the page results cached from previous requests, and the targeting operation would take longer.

Note: If you are working in a multisite environment, go to Defining Targeter Rules in a Multisite Environment.
