Online behavioral advertising (OBA) tracks users' browsing activities across websites to show relevant ads. While OBA can improve ad performance, many consumers are unaware or dislike OBA due to privacy concerns. A survey found that over half of consumers incorrectly believe their personal information is tied to OBA tracking. However, favorability toward OBA doubles if consumers are assured their personal information is not attached to tracking. More than half of consumers are more likely to accept relevant ads if they have notice and choice about how their data is collected and used.
