Header Bidding

Header Bidding is programmatic technology you can use to survey multiple demand-side platforms when a user loads a site page and select the offer with the highest bid.

How it works

1. When the user loads a site page, a special header-bidding.js code simultaneously sends requests to all connected monetizers, which then bid for impressions under the same terms and conditions.

2. All monetizer bids are received by the Adfox server with the ad request and are compared with the CPM of other Dynamic Monetization campaigns (if there are any in the site owner's account). The campaign with the maximum bid is selected.

3. The campaign with the maximum bid is compared with the Yandex Advertising Network to choose the winner:

   • If the Yandex Advertising Network bid is higher, it wins and can serve its ads.
   • If the Yandex Advertising Network can't offer a higher bid or refuses to bid, the campaign with the highest bid wins and can serve its banner.

Header Bidding advantages

• A convenient way to connect external monetizers. The full list of available monetizers is below.
• The ability to connect monetizers integrated with the Prebid.js library in a single script and monetize international traffic.
• The ability to connect to other Adfox partners that are impression monetizers without code forwarding between accounts or adding placeholders or passback tags.
• Reduced traffic losses and ad rendering time (compared to the traditional waterfall).
