If you are a publisher in the digital ad space, header bidding is likely not new to you, regardless of whether or not you've ventured into the header bidding world. There is a reason header bidding has become almost an industry standard. The resulting uplift in revenue that both web and app publishers see with the rollout of a header bidding wrapper makes it worth strong consideration.

Optimizing header bidding revenue requires dedication to data analysis, multiple header bidding integrations, and fine-tuning connections to multiple demand sources. Doing header bidding is one thing, but doing it well is a trickier proposition.

What is Header Bidding?

Header bidding is a technique used by some publishers as an additional way to bring in revenue that they might not otherwise be able to access. It came out of frustration with structures imposed by ad servers that make it so that programmatic demand can't be accessed all at once. This means publishers were leaving money on the table when awarding ad placements to bidding sources.

Programmatic Demand Bidding: The Waterfall Approach

The traditional approach to programmatic demand involves a process in which individual sources are accessed one after the other. So, the bidding process looks like this:

Essentially, you access one source and see whether it comes in with a bid request for your open ad inventory. Then you access the next source and see whether it comes in with a bid. And so on. This creates a waterfall auction.

A waterfall approach is problematic because it favors the first bid received. If a bidder comes in early in the waterfall auction, other bidders are never asked for bids. Meaning if Source A offers a $5 bid but Source B was going to bid $7, that missed opportunity for the highest bid translates to missed revenue for the publisher.

This traditional approach doesn't facilitate a competitive environment, much to the detriment of publishers and their revenue stream. An ideal situation would create an environment where Source A and Source B, and Source C, D, E... - you get the point - are competing in an auction-style format for your ad space. This is where header bidding comes in.

Header Bidding is Different

Simply put, a header bidding model creates simultaneous competition for your available ad space or ad inventory. It allows both web and app publishers to compare all bids in an auction format in order to select a winning bid, ultimately making an informed decision that will likely result in higher ad revenue.

A header bidding integration works by using a script, usually called a header bidding wrapper, that is installed within the web page itself. This differs from the traditional method which had the selection of ad sources taking place within the ad server. With a header bidding approach, additional demand sources are "talked" to before going to the ad server.

By making the ad server the last step in the process, a competitive landscape is developed where the ad server's role is to award the space to the most qualified and competitive source, instead of the first source to place a bid request. With the consideration of multiple simultaneous bids and qualifying data in an auction, publishers not only gain greater revenue opportunities, but a wider net is cast that captures quality demand sources that may have been missed with the traditional waterfall approach.

Header Bidding Stats

As we mentioned, header bidding benefits publishers by creating greater competition resulting in more revenue opportunities. But let's take a closer look at some of the stats.

 

 

7 Header Bidding Statistics to Know:

Consider that by 2021, US digital display advertisers will have invested nearly $80 billion in programmatic advertising. That is a big share of advertising budgets. And header bidding is a big part of that investment.

Header bidding is making up a big part of the digital ad industry efforts and publishers are recognizing the benefits. In Digiday and The Rocket Fuel Institute's 2016 Publishers, Monetization, and Technology: State of the Industry report, 48% of respondents agreed they received higher CPMs with a header bidding auction than the waterfall method.

When to Incorporate Header Bidding Technology

Your ad tech stack will evolve and grow as your audience grows . You don't need much more than Google AdSense or Google Ad Manager to fill your inventory in the early days.

Publisher Tech Stack (1)

As your volume of page views or daily active users grows, your ad stack will get more complicated. High-value ad units, legal and privacy matters and adding broader demand become important to publishers as they grow.

Header bidding often comes in as publishers move away from just Google's ad network or ad exchange as a demand source, typically around 300,000 page views per month for websites or 10,000 daily active users for app.

Key Considerations For Header Bidding

When it comes to header bidding, knowledge is power. The following sections highlight some of the key things to consider and take into account as you think about your approach to header bidding.

Demand Partner Breakdown

The goal of header bidding is to increase competition for your ad inventory. The more demand sources you integrate into your auction, the higher the competition will be between each potential advertiser, ultimately driving incrementally higher CPMs for each ad impression.

Building out the infrastructure to integrate and manage a set of demand sources that comprehensive is typically cost-prohibitive as a single publisher. Publishers who manage their ad tech stack in-house typically integrate between 1-5 demand sources depending upon maturity.

Additionally, incorporating premium inventory (like direct sales) to the auction also helps to increase competition, driving higher CPMs from all sources.

Another important benefit of increasing your total number of demand sources will be an increased fill rate. The more sources you have bidding on each ad request, the more likely that slot is to be filled.

Header Bidding Wrappers

In order to run, header bidding integration requires a script that will not only put your available ad placement out there but will collect bids and data from demand sources.

You can obtain this script through one of three approaches:

Build it yourself. If you have the knowledge, ad tech, and resources to build your own script, this may be an option. However, before taking it on, be certain that you and your team fully understand how to do it correctly, or you risk implementing a script that may actually prove detrimental to your efforts.

Find an open-source script. Prebid, for example, is an open-source header bidding wrapper that has emerged as the most common way for header bidding to be run on a page. You also need to know that open bidding scripts don't work out of the box, so you will need dev resources to make sure everything works as intended and all variables are being accounted for. Every bidder has its own special parameters that you have to set in order for demand to flow, and if you don't do those properly, you can miss out on a lot of revenue.

Another important thing to keep in mind is that there are bidders who are not available through the Prebid server, most particularly Amazon and its Transparent Ad Marketplace. Publishers looking to tap into all of these demand sources, and the multiple ad exchanges they allow access to, in order to maximize revenue have to consider adding additional ad tech to handle both Prebid and Amazon TAM.

Work with a partner. If you don't want to do everything that comes with building your own script or finding an open bidding script, working with a partner that offers a soup-to-nuts managed solution is ideal. A partner will not only give you a script but a proper product that handles all of the additional complexities that come with a header bidding integration.

Playwire, for example, has written a script that is entirely optimized for the purpose of reaching each source, getting responses back as fast as possible (imposing a time limit for responses), and relaying all data and bids to the ad server. We've also done the work of plugging in tons of demand sources and making sure all the relevant parameters are being passed to each one. Plus, our team handles the relationships, contracts, and other elements of header bidding, so you don't have to.

Header Bidding Complexities

Developing a header bidding system that maximizes ad revenue can come with additional complexities.

  • Client side header bidding keeps the header auction script or code on the publisher's page and it is executed on the bidder's browser when visiting the website. This means that all the logic to request and receive bids and then pick a winner is happening on the user's browser is just the start.
  • Server side header bidding is a newer approach that takes some or all of the bidders out of the page and into a separate server to run the auction. A solution like this will keep latency down and maximize user experience.
  • Amazon TAM provides access to the Amazon ad marketplace and Amazon-specific services that can become an additional monetization opportunity in combination with other header bidding services. With TAM, Amazon acts as a central hub for header bidding services, so users need to have existing relationships with multiple demand partners.
  • Amazon UAM, Unified Ad Marketplace, is similar to Amazon TAM, but publishers are able to access a list of SSPs along with the access they have to Amazon's Demand Side Platform (DSP).

Header Bidding Data and Analysis

In everything you do with header bidding, the more data you have, the better off you will be. With visibility into the data collected, you will be able to adjust your process and fine-tune your approach in order to reap the greatest benefits.

Getting your header bidding solution set up is only the beginning. There's also the ongoing process of vetting and signing up more header bidders to participate in the auction, market changes, new SSPs entering the space, and individual specialties. Add to all of that the conversations you'll need to have with bidders, the legal side of contracts with SSPs, etc. and you've got a lot on your plate. This is why professional solutions and organizations can be the best solution for publishers.
