![]() ![]() But privacy advocates have objected on three grounds:įirst, privacy advocates argue that it's currently too hard for users to find the NAI opt-out tool since users don't know which ad network is serving which ads and there's no obvious way to get from an ad to the opt-out option. NAI lets users opt-out of receiving ads based on OBA targeting. Indeed, Google has done precisely what Adam Thierer and I have called for: giving consumers more granular control over their own privacy preferences by developing better tools.įor roughly a decade, the OBA industry has operated under a self-regulatory scheme developed by the Network Advertising Initiative (NAI). The Ad Preference Manager sets a new "gold standard" for implementing the principles of Notice and Choice, which have formed the core of both OBA industry self-regulation and the various regulatory proposals made in recent years. Google's position as the leading search engine and third party ad-delivery network will no doubt cause paroxysms of privacy hysteria among those who consider targeted advertising inherently invasive, unfair or manipulative.īut those whose first priority is advancing consumer privacy, not advancing a political or regulatory agenda, should applaud Google for excluding sensitive categories and for putting the new Ad Preference Manager at the core of the company's new IBA program. Google is sure to be attacked for crossing a "line in the sand" drawn by some privacy advocates between contextual and behavioral advertising-even though Google's closest competitor, Yahoo!, already offers a similar program, and the concept in general is hardly new. Until now, (i) AdSense has delivered essentially "contextual" advertising by choosing which ad to display on a page based on an algorithmic analysis of keywords on that page and (ii) Google has tracked users' browsing only for analytics purposes-to limit the number of times a user sees a particular ad (to prevent overexposure) and to allow sequencing of ads in campaigns where one ad must follow another. This tailoring will be based on a profile of each user's interests created by tracking their browsing activity across sites that use AdSense-but not search queries or other user information. Google's new "Interest Based Advertising" (IBA) program represents the company's first foray into what is generally called "Online Behavioral Advertising" (OBA): In order to deliver more relevant advertising, Google will begin tailoring ads delivered through AdSense on the Google Content Network (GCN) and (but not ). ![]()
