Abstract
An advertiser participating in a method of targeting based on first party cookies may update its DNS record to include a subdomain that redirects to a server associated with an ad network. The ad network may incorporate that advertiser's subdomain in an ad pixel tag published on one or more of the advertiser's web pages, to set a cookie on the advertiser's domain. Specifically, when a user visits one of the advertiser's web pages, the ad pixel tag may be redirected by the advertiser's DNS update to an ad network server for receipt of a cookie that matches the subdomain. The ad network may distribute to its publishers an ad call that checks for the presence of any first party domain cookies set via the second stage, and then pass any such cookie data to the network's ad servers to decide which ad to serve.
