That 40% goes to a range of ad tech providers, data sellers and potentially inventory arbitrageurs, many—but not all—of which add value. Cutting out the ones that don’t pull their weight is difficult when the brand behind the buy has little visibility into where its dollars actually go, who all the parties to the transaction are, and whether they were all necessary to the campaign.
Enter blockchain, which could give brands the ability to track exactly where all their media spending ends up.
Fundamentally, blockchain is a list of records—a ledger—that’s open and distributed. As new records (blocks) are added to the list (chain), they’re verified cryptographically across the network maintaining the blockchain. It’s designed to be inherently secure and to allow for transparent consensus—all without putting any central party in charge.
A fully transparent and trustworthy ledger would mean that brands would finally be able to see how much of their spending ended up with the publisher, optimize the range of ad tech providers they work with based on value added to the supply chain, and avoid overpaying for arbitraged inventory—not to mention the $19 billion in ad fraud that occurs worldwide each year, according to Juniper Research.
More efficient programmatic buying also means publishers get a better cut as ad dollars are put to work.
Of course, for any of this to work, all of the parties involved must participate, using the blockchain to track their transactions. Getting so many players on board is difficult, but there’s reason to be optimistic considering the rapid adoption of ads.txt, which served a similar but more limited purpose.
With more dollars than ever flowing to digital media—including a larger share of formerly traditional-media budgets—brands are taking a closer look at how efficiently those dollars are working for them, and big spenders like Unilever and Procter & Gamble, whose CMOs have put a spotlight in the past year on transparency and accountability, appear ready to take serious steps to shrink the ad tech tax.
