Facebook has been releasing videos of presentations from sessions on various topics from its f8 conference last week. These aren't all specifically about the products they announced. Some of them are simply practical advice for using Facebook's products and getting more out of them.
This one is about "reaching the right people at scale" using Facebook's mobile app ads. As the video description says:
Get a crash course in mobile app advertising and learn how to get the most out of your ad campaigns. From finding new customers to keeping them engaged, discover how you can use mobile app ads to connect with the people who matter most for your app.
Speakers include Facebook product manager Stephanie Shum and software engineer Calvin Grunewald.
