In-app header bidding

What is in-app header bidding?

In-app header bidding is a relatively new form of automated programmatic advertising in the mobile app world. App header bidding offers app developers the opportunity to achieve maximum value for each impression through an auction, in which ad sources bid for impressions in real-time.

Header bidding vs. waterfall

Mobile header bidding is growing in popularity as developers understand the benefits it brings over the traditional waterfall. This warranted the need for a real-time auction to be introduced to the mobile app environment, given header bidding’s (the equivalent desktop solution) major success online in the desktop world, with publishers seeing a 20-40% CPM lift since implementing header bidding. Developers who have fully implemented in-app bidding no longer have to manually set up waterfalls, since the process is fully automated.
