Advertisers push Big Tech to reveal digital ad auction secrets, citing fairness and transparency concerns.
Major advertisers and industry groups are urging Big Tech firms like Google, Meta, and Amazon to adopt voluntary transparency standards for digital ad auctions, seeking clearer disclosure of bidding rules, pricing factors, and auction mechanics.
The Media Rating Council proposes these standards to increase accountability in programmatic advertising, where closed-loop auctions—used in 80% of digital ad sales—often involve hidden adjustments that can influence outcomes.
Critics argue opacity enables platforms to manipulate prices, potentially inflating costs for advertisers and reducing publisher revenue.
Though Google declined to join, Meta and Amazon are participating.
The move follows legal findings that Google engaged in anti-competitive behavior, including secretly boosting rivals’ bids.
Advertisers now seek structural reforms over past tactics like threatening to cut spending.
