The Basics: Header Bidding vs Prebid

To understand the relationship between header bidding and Prebid, it's essential to grasp their individual roles in the programmatic advertising ecosystem.

To understand the relationship between header bidding and Prebid, it's essential to grasp their individual roles in the programmatic advertising ecosystem.

What is Header Bidding?

Header bidding is a programmatic advertising technique that allows publishers to offer their ad inventory to multiple demand partners simultaneously before making calls to their ad servers. This process enables publishers to maximize their ad revenue by creating a more competitive bidding environment.

Here's a brief overview of how header bidding works: When a user visits a publisher's website, the header bidding code in the page's header sends out bid requests to multiple demand partners. These partners submit their bids within a specified timeframe. The highest bid is then sent to the publisher's ad server, which selects and displays the winning bid.

Header bidding offers several benefits for publishers. It increases revenue potential through higher cost-per-miles (CPMs) and improved fill rates. Additionally, it enhances transparency in the bidding process and gives publishers greater control over their ad inventory.

 

 

What is Prebid?

So, what exactly is prebid? Prebid is an open-source suite of software solutions designed to enable and simplify header bidding for publishers. It provides a standardized and efficient way to implement header bidding across various platforms.

The Prebid ecosystem consists of several key components:

The Prebid process works seamlessly with header bidding. When a user visits a webpage or app, the Prebid library is triggered. It sends bid requests to multiple demand partners, who submit their bids in real-time. Prebid then collects and organizes the bids, passing the highest one to the ad server.

Prebid offers significant advantages in facilitating header bidding for publishers. It simplifies the implementation process and provides access to a wide range of demand partners through its extensive adapter library. This increased competition among bidders potentially leads to higher ad revenue. 

Moreover, Prebid improves transparency in the bidding process and offers flexibility for publishers to customize and optimize their header bidding strategies.

Key Differences Between Header Bidding and Prebid

You often can’t talk about header bidding without mentioning Prebid, as it's the primary tactic used to execute that larger strategy. 

Let's break down the key differences between these terms. 

Header Bidding as a Concept vs Prebid as a Tool

Think of header bidding as the game and Prebid as one of the most popular ways to play it. 

Header bidding is the overarching strategy that allows publishers to auction their ad space to multiple buyers simultaneously. It's the concept that replaced outdated programmatic strategies like the waterfall method and revolutionized how digital ad inventory is sold. It also changed how publishers can effectively monetize their content. 

Prebid, on the other hand, is not header bidding itself but rather a set of open-source software tools designed to facilitate the implementation of header bidding. It's essentially a "header bidding enabler" that saves publishers time and effort by providing a ready-made framework.

Prebid isn't the only way to do header bidding, but it's become a go-to choice for many publishers due to its flexibility and robust feature set.
