Client-Side vs. Server-Side Header Bidding: A Comprehensive Guide for Publishers
In the dynamic landscape of programmatic advertising, header bidding has become a cornerstone technology for publishers looking to maximize revenue. Born out of the need to bypass the limitations of the traditional waterfall model and Google’s preferential treatment of its own ad exchange (AdX), header bidding has quickly evolved into an industry standard. Today, more than half of U.S. publishers have adopted some form of header bidding as their primary programmatic strategy.
However, as the technology has advanced, so too have the options available to publishers. The two primary methods of implementation—client-side and server-side header bidding—each offer distinct advantages and drawbacks. The decision on which approach to take is critical and depends on various factors such as inventory type, demand sources, and user experience priorities.
This article delves into the intricacies of client-side and server-side header bidding, providing publishers with the insights they need to make an informed decision.
What Is Header Bidding?
Header bidding is a programmatic technique that allows publishers to simultaneously solicit bids from multiple demand sources (like DSPs, ad networks, and SSPs) before calling their ad server. This enables publishers to see real-time bid values and secure the highest possible CPM for their inventory.
By allowing multiple demand sources to compete for impressions in a unified auction, header bidding has significantly increased the transparency and fairness of the bidding process, leading to better yields for publishers and more opportunities for advertisers.
However, the effectiveness of header bidding depends heavily on its implementation, which brings us to the choice between client-side and server-side header bidding.
Client-Side Header Bidding (CSHB): Transparency and Direct Control
Client-side header bidding, also known as browser-side header bidding, operates by adding a JavaScript snippet to a publisher’s website. This script is executed every time a page loads, triggering requests to multiple demand partners. Bids are collected within the browser, and the highest bid is passed on to the publisher’s ad server.

Server-Side Header Bidding (SSHB): Scalability and Performance
Server-side header bidding, also known as server-to-server header bidding, is a newer method where bid requests are sent from a central server rather than the user’s browser. This approach shifts the burden of processing from the client-side to the server-side, addressing some of the key challenges of client-side header bidding.

The Hybrid Approach: Combining the Best of Both Worlds
Given the pros and cons of both client-side and server-side header bidding, many publishers are exploring a hybrid approach that leverages the strengths of each method. By combining client-side and server-side bidding, publishers can mitigate the drawbacks of each while maximizing their revenue potential.
For example, a publisher might use client-side header bidding for display ads, where cookie matching and transparency are critical, while employing server-side bidding for video ads to reduce latency and improve user experience. This hybrid approach allows publishers to tailor their header bidding strategy to the specific needs of their inventory and audience.
When to Choose Client-Side vs. Server-Side Header Bidding
The decision between client-side and server-side header bidding ultimately depends on a variety of factors:
