When a publisher provides us this type of personal information about its users, we act as their service provider or processor of this information on their behalf, by passing the information to advertisers so they can respond with an ad they believe will be relevant to you.</p>How does TRUSTX facilitate interest-based advertising?<p>The TRUSTX Advertising Marketplace passes technical identifiers – cookies, device identifiers and similar technologies – to buy-side technology providers or buyers, who use this information to transact in an automated fashion. Because some of these identifiers are persistent across the Internet, ads may be customized based on interests generated from a user’s visits to different websites via the same browser or device.
