US v. Google offers a rare look at Google's top 20 queries by revenue for a week in September 2018: iPhone, insurance, cheap flights, online colleges, and more
Context & Ripple Effects
The disclosure adds query-level revenue detail to the search-distribution record in Google’s payments to secure default placement and later testimony on its much larger default-search spending. It makes concrete which commercial intents sat behind the broader competition case.
The presence of iPhone-related searches also connects revenue-bearing search demand to the device ecosystem, rather than treating Google’s default-position agreements as an abstract distribution issue.
First-order effects
- The trial record gives advertisers, publishers, and antitrust observers an unusual view of the query categories that generated substantial search revenue during the disclosed 2018 week, including travel, insurance, education, and iPhone-related demand.
- Google’s search monetization model receives more granular scrutiny: the evidence links high-value commercial queries to the company’s effort to preserve default access, later described in testimony on $26.3B in default-search spending.
Second-order effects
- Advertisers in the disclosed categories gain a clearer signal that competition for search placement is concentrated around high-intent queries, reinforcing the importance of bidding, landing pages, and conversion measurement in those markets.
- Platform partners and regulators can evaluate default-search deals against the economics of the queries those defaults help capture, not solely against aggregate traffic or market-share measures.
Third-order effects
- If similar evidence continues to emerge, antitrust debates over search distribution will increasingly turn on the value of commercially actionable demand and the routes through which it reaches a search engine.
- The record points to a durable tension in search: default distribution can shape access to the highest-monetizing queries, making route control consequential even when users can technically switch services.
The trend: Search competition is being assessed less as a generic contest for queries and more as a contest for distribution to high-value commercial intent.
