Header Tag Demo

In this demo, we ask you to select your interest. In real life, however, we will obtain your (or your site visitor's) interests via our integration with DMPs such as LiveRamp and Bluekai.

We have set up a campaign with 3 lines, targeting audience with interests in food, fashion and auto. When you click on any of the above, a cookie will be put in your browser with the selected interest. In the next screen, C1X audience platform servers will receive your cookie via a header tag, even before the page is rendered. C1X will select the best line that matches the user's interests and will direct DFP to serve that line.
