::''Acceptable Example:''
::A site wishes to track conversions after a user interacts with an ad. The site can annotate the landing page URI of outbound advertisements clicks with information about which advertisement was clicked and from which publisher. When a user later completes a conversion action, third-party code from the site transfers information about the advertisement that led to the conversion back to its servers, such that an aggregate number of conversions can be computed. This is acceptable under our policy because because it does not involve the creation of a user profile.
