Remarketing

Showing ads to people selected because they have already visited an advertiser's own website or used its app. The same practice is also called retargeting. A measurement pixel on the site, or its counterpart in the app, records visitors and the pages they view, and the advertising platform groups the visitors into lists. The advertiser picks a list, and the platform shows the advertiser's ads to the people on it when they later use other sites and apps in the platform's network. In the dynamic form, the ad shows the exact product the person viewed. In the European Economic Area, the law allows a visitor on a list only after the visitor agrees to the recording.
