Ad Mediation Waterfall vs Unified Auction

Interactive 3D ad-monetization simulator: watch the same mobile ad-impression traffic flow through a sequential mediation waterfall and a unified real-time auction side by side, and compare fill rate, effective eCPM and revenue per minute live.

Mobile app advertising revenue depends heavily on how the app's SDK decides which ad network fills each impression. This simulator streams the same traffic of ad-impression requests through two real ad-serving architectures side by side in 3D: a classic sequential mediation waterfall, which tries networks one at a time in priority order and pays a latency cost on every failed hop, and a unified real-time auction (header bidding), which asks every network at once and awards the impression to whichever bid is highest. Five networks with fixed price and fill-probability profiles feed both lanes identically, and live readouts track fill rate, effective eCPM and projected revenue per minute so you can see exactly why the ad-tech industry moved toward unified auctions.
