AEO (Answer Engine Optimization) is the practice of optimizing content to be cited by AI-powered search engines: ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot. The US market is the frontline of AI search adoption - 60% of Google searches in the United States already trigger AI Overviews, making AEO an urgent priority for American content professionals.

No, SEO is not dead. But in the US market - the most AI-search-saturated market in the world - SEO has undergone the most dramatic transformation. 60% of US Google searches now include AI Overviews, ChatGPT Search is growing rapidly, and the traditional "10 blue links" result is disappearing for many query types.

The United States is ground zero for AI search disruption. SERPs combining AI Overviews with paid ads grew 394% year-over-year. Over 60% of US Google searches now include AI Overviews - the highest concentration globally. For US SEO professionals, this is not a trend to prepare for. It is the current reality demanding immediate strategic adaptation.

In the US market - where AI Overview coverage exceeds 60% of all searches - off-page SEO is no longer just about organic rankings. External authority signals now directly determine whether your content appears in AI Overviews or gets permanently displaced below the fold. High-DR sites are cited in AI Overviews at 3-5x the rate of low-DR equivalents for the same content quality.

The US is the most AI-search-saturated market in the world. With 60%+ of US Google searches including AI Overviews, traditional SEO ranking data tells only part of the story. The critical metric for US publishers in 2026 is AI Overview citation rate - and measuring that requires specialized tools that most US SEO teams don't yet have in their stack.
