For US-based websites, the Seer Interactive finding hits hardest: AI Overviews have been most aggressively deployed in the American Google Search market. The study of 3,100 queries found a 61% average drop in organic CTR when an AI Overview is present - and in the US, AI Overviews appear on an estimated 40-50% of informational queries. This is not a future concern; it is the current reality for US SEO programs.
The US search market had already seen CTR compression from Featured Snippets, People Also Ask boxes, and ads expansion. AI Overviews represent a larger structural change - one that requires updating how US SEO is planned, measured, and reported.
The US Context: Where AI Overviews Are Most Active
The United States is the primary market for Google's AI Overview deployment. While the feature is rolling out globally, the US has had the longest exposure and the highest coverage rates. For US SEO professionals, this means:
- AI Overviews appear on a higher percentage of US queries than any other market
- The 61% CTR drop is most directly applicable to US search data
- US organic CTR benchmarks that have not been updated since 2024 are now significantly overstating expected traffic
- The commercial impact is real: US websites in competitive niches have seen material organic traffic declines for informational content
Major US verticals most severely affected include technology (how-to content), healthcare (symptom and treatment information), finance (rates, explanations, how-to), legal (procedure explanations), and consumer goods (comparison and review content).
Position 1 CTR in US Search: The New Reality
The Seer Interactive data puts Position 1 CTR on AI Overview-affected queries at approximately 11% in the US market. For context:
| Year | Approx. Position 1 CTR (Informational) |
|---|---|
| 2021 | 28-32% |
| 2023 | 18-22% |
| 2024 | 14-18% |
| 2026 (AI Overview present) | ~11% |
This trajectory shows that the AI Overview is the latest in a series of SERP feature changes that have progressively reduced the click value of Position 1. The difference with AI Overview is scale - it affects a much larger share of queries than Featured Snippets did.
For US SEO reporting purposes, this means: if your site's average CTR has dropped 40-60% on informational pages despite stable rankings, AI Overview is likely the cause, not a technical issue with the site.
US Query Types: Who Loses Most
In the US market, the most severely affected queries align with the highest-volume informational content categories:
High-volume US informational niches with severe CTR impact:
- Health information ("symptoms of X", "how to treat X") - CTR drops 70-80%
- Financial how-to ("how to invest in X", "what is a 401k") - CTR drops 60-75%
- Technology tutorials ("how to use X", "X vs Y software") - CTR drops 65-75%
- Legal explanations ("what is X law", "how does X legal process work") - CTR drops 60-70%
US niches with moderate CTR impact:
- Product research ("best X for Y use case") - CTR drops 30-45%
- Consumer comparison content ("X vs Y car", "X vs Y insurance") - CTR drops 35-50%
US niches minimally affected:
- Local services ("plumber in [city]", "restaurant near me") - CTR drops 5-15%
- eCommerce transactional queries ("buy X online") - CTR drops 15-25%
- Branded US company searches - minimal impact
The US SEO Strategic Response
Priority 1: Revalue your content portfolio
US companies that built large informational content programs ("answer every question your customer might ask") need to reassess the traffic model for that content. The informational content still has value for brand awareness, topical authority, and AI Overview citations - but the direct traffic ROI has dropped significantly.
Priority 2: Invest in transactional and commercial intent pages
Bottom-of-funnel US content - pricing pages, "best X" with commercial intent, case studies, service comparison pages - maintains stronger CTR despite AI Overview. These pages also convert better, making the reduced traffic more valuable.
Priority 3: Build AI Overview citation strategy
US brands cited in AI Overviews maintain a presence in the SERP even when clicks go elsewhere. The strategy: complete Article schema, authoritative author markup (especially important for YMYL content), frequent content updates, and structured Q&A content that feeds AI extraction.
Priority 4: Measure AI Overview impact directly
Use Google Search Console to identify which US queries now trigger AI Overviews and compare historical CTR. This data should inform which content categories to prioritise and which to deprioritise in future content investments.

Frequently Asked Questions About AI Overview CTR Impact for US Websites
Is the 61% CTR drop from AI Overviews applicable to US search specifically? Yes. The Seer Interactive study was primarily based on US Google search data, making it directly applicable to US websites. The US is also the market with the highest AI Overview coverage rate, meaning the effect is most pronounced here.
Which US content categories have seen the largest organic traffic losses from AI Overviews? Healthcare, finance, technology how-to, and legal explanation content have seen the largest losses - 60-80% CTR drops on affected queries. These are also the highest-volume informational content categories in the US market.
How should US SEO reports be updated to reflect AI Overview CTR changes? Update CTR benchmarks: Position 1 for AI Overview-affected queries should be modelled at approximately 11%, not 28%. Separate reporting should distinguish queries where AI Overview appears from those where it does not. Historical year-over-year comparisons need this context to be meaningful.
Are US eCommerce sites as affected as informational sites? No. US eCommerce transactional queries ("buy X", "X near me", "X price") see much lower CTR drops - approximately 15-25%. The AI Overview is less likely to appear for purchase-intent queries, and users clicking for eCommerce purposes are more motivated to click through.
What US brands are successfully adapting to AI Overview CTR changes? Brands succeeding in the new US search landscape typically combine three things: strong transactional content at the bottom of the funnel, active AI Overview citation strategy through structured content and complete schema, and traffic diversification into email and direct channels.
