Google Offers Court More Insight into Advertising Data

Wed 1st Oct, 2025

In an ongoing legal battle, Google has proposed to enhance transparency regarding its online advertising processes as it faces competition-related concerns. A recent ruling by a U.S. District Court highlighted that Google has secured monopolistic control over key areas of the advertising industry, specifically in advertising servers and exchanges utilized for web advertisements.

The court's April decision deemed the integration of Google AdX, the company's advertising exchange, with the DoubleClick for Publishers ad server as unlawful. Currently, discussions are taking place in court to determine the necessary remedial actions following these findings.

A Google representative recently suggested that the company is willing to provide website operators with increased insight into how its advertising exchange determines which ads are displayed. Traditionally, Google has conveyed the impression that ad selection occurs through rapid auctions where the highest bid wins. However, the process is significantly more complex and lacks transparency.

During testimony at the U.S. District Court for the Eastern District of Virginia, a senior programmer from Google Ad Manager stated that granting website operators more visibility into the auction mechanisms would be a positive step, although he noted that the intricacies involved might be overwhelming for many operators. He recommended that publishing technical documentation could suffice in addressing the concerns raised.

The legal proceedings commenced in early 2023 following a competition lawsuit filed by the U.S. government under the Biden administration, along with eight states. The lawsuit alleges that Google's dominance in the market adversely affects advertisers, who face inflated costs, and web operators, who receive inadequate compensation for ad placements. Google reportedly retains an average of 35% of the revenue through various fees within this ecosystem.

While Google has denied the accusations, it has not managed to convince the court of its perspective. The court dismissed only one of the claims against Google, which accused the company of unlawfully monopolizing the advertising network market. However, the court upheld the remaining three claims against the tech giant, leading to calls from the government's legal team for Google to divest its advertising exchange and disclose its auction methodologies. Such a divestiture would disrupt Google's control over the online advertising supply chain.

The case is officially titled USA et al v Google and is currently pending in the U.S. District Court for the Eastern District of Virginia under case number 1:23-cv-00108.
