Google has made a recent webinar on real time bidding with audience targeting available for everyone.
Google says in the description, "In this Learn with Google Hangout On Air we'll explain a new bid strategy, Target ROAS. By walking through how to setup conversion values in conversion tracking and an actual bid strategy in AdWords, we'll demonstrate how to best use this new tool. The Hangout On Air will include information from case studies and Google product experts."
It's about an hour long.
