IAB Ads.txt & Sellers.json Compliance
Ensure 100% programmatic authorization and prevent domain spoofing with automated Ads.txt validation, Sellers.json transparent node publishing, and SupplyChain Object (schain) signal passing.
Official NexusSSP Ads.txt Integration Snippet
To authorize NexusSSP as a legitimate seller of your domain's ad inventory, paste the following line into your website's https://yourdomain.com/ads.txt file:
Sellers.json Node
Every publisher account receives an automated Sellers.json entity record containing seller type (PUBLISHER) and verified business domain.
SupplyChain (schain)
OpenRTB requests append strict OpenRTB SupplyChain nodes to prove inventory origin and eliminate hidden intermediary markups.
Automated Crawler
Our automated Ads.txt crawler verifies publisher domains every 24 hours to ensure continuous DSP bid eligibility.
