IAB Seller.json explained and how to avoid ad revenue loss

This post was most recently updated on September 1st, 2021

The IAB tech lab recently released a new technical specification called Sellers.json.The goal of Sellers.json is to help ad buyers verify publisher inventory and increase the trust of the supply chain on the supply side of real-time bidding and programmatic buying.

The Sellers.json file offers a reliable way for buyers to identify direct inventory versus reseller inventory. This type of relationship is also defined in ads.txt. However, ads.txt does make any attempt at revealing the identities of publisher account IDs within their advertising platforms. This new development will help sellers verify publisher identities and include details on the name, domain, and seller ID.

How to avoid revenue loss and enable Sellers.json

Publishers can enable the Google Sellers.json file via Google Ad Manager. Be sure to read more about it in the Google Ad Manager help center article here.

To avoid ad revenue loss, publishers need to make the change through their Google Ad Manager account before May 28th, 2020. Here’s how to do it:

Go to Google Ad Manager > Admin > Global Settings > Ad Exchange Account Settings > Toggle Sellers.Json transparency on > Click Save

Once you’ve made the change, your business name, domain, and publisher ID will appear in the Sellers.json file. You can see your business name in Google Ad Manager > Billing > Payments > Payment profile rules in “Business name and address.”

Be sure to check out our video on the Sellers.json update for more information below:
