Header Bidding

A programmatic advertising technique that allows multiple ad exchanges to compete for ad impressions simultaneously.

Header Bidding is a programmatic advertising technique that allows publishers to offer their ad inventory to multiple ad exchanges or demand-side platforms (DSPs) simultaneously before making ad-serving decisions. It is designed to maximize revenue and optimize ad buying by creating a fair and competitive auction environment.


There are different Header Bidding solutions available in the MarTech Industry, including:

  1. Prebid.js: Prebid.js is an open-source header bidding wrapper widely used in the industry. It allows publishers to integrate multiple demand sources, such as supply-side platforms (SSPs) and ad exchanges and facilitates real-time bidding for each impression. Publishers can customize and manage their header bidding setups using Prebid.js, providing flexibility and control over their ad inventory.
  2. Google Ad Manager: Google Ad Manager offers a comprehensive header bidding solution, allowing publishers to use Google's tools and services to implement header bidding and manage their demand sources effectively. With Google's extensive reach and access to demand, publishers can leverage header bidding to increase competition and optimize their ad revenue.
  3. Index Exchange: Index Exchange is a supply-side platform (SSP) that provides a header bidding solution for publishers. Their platform lets publishers connect with multiple demand sources simultaneously and optimize their ad auctions in real time. Index Exchange offers advanced analytics and reporting features, allowing publishers to monitor performance and make data-driven decisions.

Benefits and Utilities

  1. Increased competition: Header bidding simultaneously opens up the ad inventory to a broader range of demand sources, increasing buyer competition and leading to higher bids and increased revenue potential for publishers.
  2. Revenue optimization: By allowing multiple demand sources to bid on inventory in real time, header bidding maximizes the chances of getting the highest possible bid for each impression, helping publishers to optimize their revenue streams.
  3. Improved fill rates: Header bidding enables publishers to access a larger pool of demand sources, increasing the likelihood of filling ad placements with relevant and high-paying ads. This results in improved fill rates and reduced ad inventory wastage.
  4. Transparency and control: Header bidding gives publishers more control and transparency over the ad buying process. They can see the bids from various demand sources and make informed decisions about which ads to serve, ensuring the best possible user experience.
  5. Reduced latency: Traditionally, waterfall-based ad serving involves a sequential process in which ad requests are sent to one demand source at a time, potentially causing delays. In contrast, header bidding allows multiple demand sources to bid simultaneously, reducing latency and improving website performance.
  6. Increased monetization options: Header bidding enables publishers to diversify their revenue streams by tapping into various demand sources, including programmatic exchanges, direct deals, and private marketplaces, expanding monetization opportunities and reducing reliance on a single ad network.
  7. Data insights and optimization: Header bidding solutions often provide data and analytics that offer insights into bid performance, buyer behavior, and ad performance. Publishers can leverage these insights to optimize ad inventory, pricing strategies, and overall revenue generation.

By leveraging header bidding within their MarTech stack, publishers can maximize revenue potential, improve user experiences, and make more informed decisions in the ad serving process.
