How Does Prebid.js Work


Prebid.js fetches bids

The ad server’s tag on page is paused, bound by a timer, while the Prebid.js library fetches bids and creatives from various SSPs & exchanges you want to work with.

Prebid.js passes bid information

Prebid.js passes information about those bids (including price) to the ad server’s tag on page, which passes it to the ad server as query string parameters.

Ad server targets bid parameters

The ad server has line items targeting those bid parameters.

Ad server signals Prebid.js

If the ad server decides Prebid wins, the ad server returns a signal to Prebid.js telling the library to write the winning creative to the page.

The Prebid.js library is composed of these pieces:
  • The Core wrapper code
  • The Adapters a publisher wants to work with
  • Optional modules the publisher wants to utilize
