Ep 10: Header bidding timeouts

0:54 · October 31, 2026

Your auction waits for the slowest bidder — or it doesn’t. Set the timeout from data.

Lesson notes

Your auction waits for the slowest bidder. Or it doesn’t. Prebid’s auction timeout (bidderTimeout in the config) decides when it stops waiting. Wait longer and late bids can make it, but the ad loads later. Cut it short and the ad comes sooner, but late bids miss out.

Your to-do: check your analytics for bidders that keep timing out. Look by region, then call them first, stop waiting for them, or skip them where they lag.

Set the timeout from data, not from a blog post.
