🔥 Tier 1 - Must KnowID: headerBidding
Header Bidding
Simultaneous auction tech allowing all exchanges to bid on inventory before ad server calls
In Simple Words (Zero Jargon):
Code on a webpage that lets all ad networks bid at the exact same time, creating fair competition instead of giving Google or one network first dibs.
Why It Is Critical
Header bidding eliminated the outdated sequential "waterfall" model, giving advertisers fairer access to premium publisher inventory and boosting publisher yields.
What You Get: Fairer and more reliable access to premium publisher ad placements without being locked out by sequential waterfalls.
