Method of storing a web user ID in first-party cookies
Third party ad servers log a user's web browsing activities. On web pages where the ad server is a third party, the web page's code is configured to provide the ad server read and write access to an advertiser's first party cookie on a user's web browser. The ad server uses this access to read and write a unique user identification number to the cookie. The ad server also maintains a separate copy of the user identification number on a remote server. Correlating the user identification both within the ad server and within the cookies stored in the user's web browser allows the ad server to identify and log the web traffic associated with particular users. This information is useful in a number of contexts, including determining which ad inventory to purchase for which users, and how to value the corresponding ad inventory.
