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

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

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:
