Comscore: AI Is Now a Mainstream Habit, Upending Search and Ads

Comscore's new "2025 AI Intelligence Report" confirms generative AI has become a daily habit for a huge portion of the U.S. population, with adoption rates that are fundamentally altering the mechanics of web search and digital advertising. The findings show AI assistants now reach 36% of desktop users and 24% on mobile, establishing a new baseline for consumer behavior.

• The search shake-up: The most jarring data point is for anyone who relies on search traffic, as over 30% of Google desktop searches now feature an "AI Overview." That change directly threatens publisher traffic by upending the old model of SEO-for-clicks, creating a new imperative to optimize content for citation within AI summaries.

• Advertisers on notice: The ripple effect is hitting advertisers hard, forcing them to treat AI as a primary channel for discovery. With nearly two-thirds of hotel bookers now visiting an AI platform before buying, brands have to overhaul their media plans and attribution models for a world with fewer direct clicks.

The report is also a clear strategic play by Comscore to position itself as the measurement "currency" for the AI era. As the company itself states, "AI has rewritten the rules of consumer interaction and brands must now adapt their strategies to meet customer needs in this new and evolving environment." Comscore is also pushing further into automation through a new partnership, while its leadership is taking to professional networks to frame the report's impact.
