Definition: Header Bidding Demand Partner

What is a header bidding network?

A header bidding demand partner is a source of demand for your ad inventory. These are the networks you program your header bidding wrapper to send calls to when a user visits your app or website. These partners then call up their internal demand to bid in the auction for your inventory.

Most publishers know that having broad demand for your inventory is a good thing for your yield. It’s a relatively simple concept: more competition leads to better financial outcomes for the supplier (read: you, the publisher). 

This is a big metric on which to measure header bidding demand partners - do they give you access to a ton of demand? If they don’t, they are unlikely to be worthwhile. If you’re left confused about how to choose the best header bidder, it’s a little simpler than you may think: you don’t have to choose one - you can choose several and include them all in your auctions.

Most Popular Header Bidding Networks

Dozens and dozens of ad tech companies have tried to capitalize on the innovation that is header bidding, and many have done so successfully by providing a quality product that truly helps publishers grow their revenue. Below, we discuss the nine most popular header bidding wrappers, as reported in research published in 2021.

1. Amazon

Around 71% of all websites participating in header bidding include Amazon in their list of demand sources, and there’s a good reason for that. Amazon has nothing short of world dominance in a wide variety of industries - digital advertising included. That means they have plenty of demand across their ad network for any publisher to access.

Publisher Benefits:

  • Earnings from all buyers combined and paid to publishers within 60 days
  • Simple server-side bidding integration
  • Leverage massive amount of first-party data from Amazon customers

Reviews: 

It seems that Amazon is somehow so ubiquitous in the header bidding wrapper space that it hasn’t made its way onto popular reviews sites like G2 or Capterra, but user testimonials sourced from social media sites tend to focus less on usability or features and more on demand: You won’t get the fullest demand possible if Amazon isn’t somewhere in your header bidding mix.

2. Index Exchange

Sixty-two percent of publishers doing header bidding include Index Exchange in their deck of demand partners. With a focus on new ad tech developments and access to premium global demand, Index Exchange is certainly a contender for any publisher looking to increase their revenue with header bidding.

Publisher Benefits:

  • Internal focus on ad exchange quality
  • Consolidates, display, video, OTT and mobile monetization in one tool
  • Maintains demand relationships with leading global agencies

Reviews: 

Index Exchange hadn’t made the rounds on any of the popular reviews sites, including G2, Capterra, TrustPilot and TrustRadius, as of publication time, so take from that what you will. Still, we know that the majority of publishers doing header bidding use Index Exchange as one of their header bidding networks, so it can’t be too bad.

3. Magnite

Telaria, the Rubicon Project and SpotX merged their wide access to advertiser demand to create Magnite, a header bidding demand partner that takes a “header bidding software made easy” approach to its marketing. By all accounts, the approach is working - 53% of publishers use Magnite in their header bidding strategies.

Publisher Benefits:

  • Real-time performance dashboard
  • Run by co-founders of Prebid.org
  • Extensive private marketplaces for premium deals

Reviews: 

With a 3.2 out of 5 stars on G2, Magnite appeared to be winning most of its publishers’ hearts but not all of them. Positive reviews discussed robust reporting and a user-friendly interface. But negative reviews mentioned issues like slow loading and low fill rates.

4. PubMatic

PubMatic has built an enterprise header bidding wrapper on top of Prebid.js, and it’s attractive to a lot of publishers who are doing header bidding - 48% to be exact. Broad demand drives the attraction to this header bidding network, but the wrapper they’ve built comes with some additional handy features, such as A/B testing, in-depth analytics and a baked-in identity management tool.

Publisher Benefits:

  • Built-in A/B testing functionality
  • Broad private marketplace offerings
  • In-depth ad quality tools

Reviews: 

For being such a popular header bidding software, PubMatic hasn’t amassed many online reviews. The tool had no reviews on Capterra and just a handful on G2, with an average of 3.2 out of 5 stars. Most of the negative assessments of PubMatic centered on customer service issues, and the positives were often about time-saving features like workflow automation.

5. Xandr

Although you might not have heard of it, the vast majority of publishers who are doing header bidding have. Xandr came in at a close second to Amazon, with 69% of websites using header bidding networks using the platform. Xandr uses Prebid’s header bidding framework to bring a wide variety of header bidding-related services to publishers on top of access to huge inventory demand. 

Publisher Benefits:

  • AI-powered forecasting analytics
  • Entire division devoted to over-the-top (OTT) header bidding
  • Custom-built and integrated ad server

Reviews: 

Xandr had no reviews on Capterra as of the time of publication, but on G2, the reviews were somewhat positive, giving the tool a 3.7 out of 5 stars. Many reviewers said the tool is user-friendly and comes with solid customer service, but others complained about delayed creative approvals gumming up the programmatic works.

6. OpenX

Procter & Gamble, LinkedIn, HP and GM are among the buyers OpenX has worked with, which suggests that the demand this header bidder can get you access to is not only broad, but premium. That’s likely a big part of the reason why 43% of publishers who do header bidding work with OpenX.

Publisher Benefits:

  • Direct outreach to buyers to create publisher inventory packages
  • Features ID resolution product OpenAudience
  • Works with more than 100,000 advertisers

Reviews: 

Capterra featured no reviews of OpenX, and G2 had just a handful that averaged out to 3.1 out of 5 stars. The positive reviews highlighted strong reporting capabilities and the tool’s willingness to work with publishers of any size. The negative reviews highlighted scale limitations with video inventory and bugs in the software.

7. TripleLift

With 32% of publishers trusting them with their header bidding demand, TripleLift boasts a broad network of publishers and an equally broad network of buyers. TripleLift does programmatic advertising across a variety of channels and formats, but it maintains a special focus on native advertising.

Publisher Benefits:

  • Extra focus on creative design and delivery to create premium advertiser experiences
  • Works with 100% of the AdAge 100
  • Partners with leading ad fraud prevention tools

Reviews: 

With 4.2 out of 5 stars on G2, TripleLift enjoys relatively broad support from the publishers who use it. Happy publishers mentioned the fact that TripleLift focuses on native advertising, and the unhappy ones said the tool’s targeting capabilities left something to be desired.

8. Sharethrough

As a demand partner, Sharethrough provides multiple channels of communication from which publishers can harvest ad revenue. As a primary benefit, the platform focuses on real-time bidding, providing premium experiences for users and advertisers, and ultimately improving the value of your inventory to increase your revenue potential.

Publisher Benefits:

  • Automatic syncing for display ads provide an interruption-free browsing experience for users
  • Dynamic video captions to help improve video ad engagement
  • Pre-built templates that allow publishers optimize their ad formats

Reviews: 

Sharethrough works with some of the largest companies in the world including Amazon, T-Mobile, and Uber. They have solid ratings from their customers, too: 4.5 out of 5 on G2 and one rating of 7.3 out of 10 on TrustRadius.
