OPM is a process used by network advertisers whereby data is typically collected over time and across Web pages to determine or predict consumer characteristics or preferences for use in ad delivery on the Web. The OPM process can use non-personally identifiable information or a combination of personally identifiable information and non-personally-identifiable information.
OPM does not refer to the use of data by network advertisers for Ad Delivery and Reporting. OPM excludes the use of data provided by a Web site or advertiser directly to the network advertiser and used by that network advertiser for Internet advertising solely on behalf of such Web site or advertiser.
