The Complete Header Bidding Guide

Traditional waterfall mediation is failing modern publishers. By ranking ad networks in a fixed, predetermined order based on historical data, the waterfall model creates a structural revenue leak where higher-paying bidders are often ignored simply because of their rank. Header bidding solves this by flipping the auction model entirely, allowing all demand partners to bid simultaneously before the ad server is even called. Whether you are a hyper-casual game developer or a cross-platform creator using Flutter or Unity, understanding the technical nuances between client-side and server-side auctions is critical. While client-side offers transparency, server-side bidding is often preferred for mobile apps to reduce latency. By integrating header bidding into your ad mediation platform, you move away from managed queues toward a live, competitive market, ensuring you capture the true market value of every single impression.
