Using the contact behavior profile

 In the Marketing Control Panel, you can control how long an individual profile or pattern card is relevant to the contact behavior profile by setting the decay rate. The decay rate is a percentage that expresses how relevant the profile will remain over time. ![Marketing Control Panel with contact behavior profile example](https://doc.sitecore.com/api/markdown-image/xp/en/users/100/sitecore-experience-platform/images/E188EF325A6A4A9D808FE208CB45BF28.png) You can implement [personalization rules](https://doc.sitecore.com/xp/en/users/100/sitecore-experience-platform/the-rule-set-editor.html "The Rule Set Editor") based on the values in a contact's contact behavior profile to show personalized content based on past profile matches instead of the current profile matches. This enables you to provide more relevant information to a contact over the course of their relationship with your organization.
