Ranking bidders by revenue alone hides why they underperform.

Lesson notes

Ranking bidders by revenue alone hides why they underperform.

A Prebid analytics adapter records each bidder’s requests, bids, timeouts and wins.

Prebid.js fires an event at each step of the auction. An analytics adapter, from a vendor or in-house, sends those events to a dashboard. Say Bidder C got ten thousand requests on recipes.example. It bid four thousand times, a forty percent bid rate. It won four hundred, a ten percent win rate. Fifteen hundred answers came after the timeout, a fifteen percent timeout rate. A low bid rate points to setup, consent or demand. A low win rate means it bids, but low. A high timeout rate means its bids arrived too late, so check speed before you drop the partner.

Today, confirm your build has an analytics adapter, then find your highest timeout rate.
