App install and engagement fraud cost mobile advertisers up to $350 million this year. Paying for bad installs first and negotiating a refund later means taking only a reactive approach to this massive issue – instead, you need early indicators of fraudulent traffic that you can act on right away. In this session, you’ll learn how Game Circus uses a variety of anti-fraud techniques as well as device-level data to prevent bad installs before they occur.
