We may also use non-personally identifiable information to determine whether to serve an advertisement to a user … and which advertisement to serve. For example, we may use a cookie to determine whether a particular ad has already been viewed by a user so that our server won’t deliver the same advertisement a second time. If an advertiser wants us to deliver a series of advertisements in a particular sequence, we may use a cookie to note that the first ad has been delivered to a particular user so our server knows to deliver the second ad in the series when that user next visits a Genius Monkey site. </li> <li>
