You can collect highly detailed information about your bidders (winning bids) and their behavior if you are using Prebid.js with Permutive. Use this data to understand your header bidding data, including:

• Detailed insights on bidding behavior for each slot by the bidder and by cohort.
• To optimize the partners you work with within your header bidding stack
• To debug issues with your header bidding stack
• To go direct to bidders and offer them a first look at their desired audiences, based on your understanding of their bidding behavior

We recommend collecting winning bids for each ad slot.

Every Prebid event will have default data and additional data from Prebid. You can read more about the data that is available on the Prebid.js API. We recommend collecting events with these properties:

Deal ID (String)

HB PB (String)

Height (Integer)
