Programmatic is a continually changing area in digital advertising and can be rather complex in places. One area of huge change over the last few years has been the wide-scale publisher adoption of Header Bidding which has resulted in dramatic innovation in the digital advertising ecosystem. Evolving bidding strategies, supply path optimisations and industry solutions to fight fraud are perpetually being worked on. The IAB’s tech lead Jonas Jaanimagi sat down with Rohan Creasey, Country Manager, ANZ at Rubicon Project (who helped author the recent IAB Auction Mechanics handbook and is a bit of an expert on the topic) about Header Bidding, it’s adoption and direction – including the new OpenRTB protocols, why it’s important and its impact on both the buy-side and sell-side. Rohan and Jonas also discuss the IAB Executive Technology Council and its forthcoming mentorship program to help support and develop up-and-coming talent in our industry.
