Marketers want a leaner supply chain while maintaining addressability

Brands are looking for ad-tech efficiencies, but the process has been complicated by players like Google.

Key supply path optimization insights:

  • Privacy and need for performance are driving optimization.
  • Duplication remains, but for a reason.
  • Brands now see data as a first-party asset.
  • Marketers have begun building their own walled gardens.

Under pressure to comply with privacy regulations and prove their programmatic ad buys are delivering value, marketers are looking to source ad inventory more directly—even as Google’s rollout of Open Bidding threatens to frustrate that.

Additionally, media spend via supply sources that use ads.txt–an IAB-led transparency initiative–increased by 45% year-over-year in Q4 2019, while spending on less trusted sources, typically called “unauthorized resellers,” decreased significantly.

These are some of the key findings in separate reports recently from BidSwitch, a company that builds the infrastructure of much of the ad-tech ecosystem, and Jounce Media, which just released its latest benchmarking report. Taken together, these reports highlight how marketers want a leaner supply chain while keeping the addressability that’s at the core of the ad-tech world.

Privacy performance requirements drive SPO

Barry Adams, general manager at BidSwitch, told Adweek the drive to prune the supply chain–commonly called supply-path optimization, or SPO–was driven by the need to comply with privacy regulations, as well as improving transparency.

“Transparency promotes the value of direct transactions with publishers as well,” Adams said, commenting on the ads.txt initiative. “In addition, cost-effective ways to secure premium inventory is valuable knowledge for ad buyers as the world moves away from third-party cookies.”

The increased focus on transparency, along with expanding privacy laws, also saw media buyers willing to pay a premium for direct transactions with publishers, demonstrated by higher revenue figures for media trading undertaken via private marketplaces.

This trend is favoring publishers with BidSwitch data, which analyzes 50 trillion ad requests per quarter, demonstrating that ad prices conducted via private marketplaces are on average 3.2 times higher than inventory sold across open ad exchanges.

Duplication remains, but for a reason

Jounce Media’s study, however, found that auction duplication—in which a single ad impression is simultaneously offered to advertisers across a number of different ad exchanges—has seen a slight increase in 2020.

On average, publishers used 21.6 supply paths in March 2020, up from 21.1 in February and 18.3 in January, partly the result of the sell side of the industry embracing Google Open Bidding, also known as Google Exchange Bidding, in Google Ad Manager.

According to Jounce Media, Google Open Bidding presents marketers with an SPO dilemma. Even though many on the buy side want to reduce the number of intermediaries they work with, enabling Open Bidding improves auction win rates, which means they have to cut an additional check to Google.

“We’ll see principals come closer together on both the supply and demand side,” said BidSwitch’s Adams, “but that doesn’t mean the collapsing of the supply chain—it could just mean that we have a [smaller] more transparent supply chain.”

For Adams, advertisers should know how each tier of the ad-tech ecosystem provides value before they decide which parties will lose out during SPO-driven reduction efforts.

“I think that for agencies it will be a big thing,” Adams said. “They’re starting to say to themselves, ‘Yeah, I’m interested in accessing that publisher, but do I need to see it across 14 different exchanges?’ And we all know the DSPs have been thinking about this for a while.”
