Ad-tech & the adult-web supply chain
The adult web runs on a small set of specialist ad networks, trackers, and card billers that mainstream analytics rarely surface. We measure it directly: each site in the census is rendered in a real browser and its third-party resource hosts are recorded, then cross-checked against declared ads.txt and sellers.json. The tables below rank each vendor by how many measured sites load it.

Method: third-party hosts are read from each site’s rendered DOM plus its declared ads.txt/sellers.json; a vendor is “named” when its domain matches our tech catalogue. Counts are of sites where the vendor was observed, across the full census (not only profiled sites). Runtime bidder capture is a planned enhancement.
