The US is the world's most advanced AI search market. Google AI Mode has 38.2 million monthly visits, Perplexity attracts 50+ million users, and ChatGPT Search is actively used for queries that used to go exclusively to Google. American users are already changing how they search - and the question for publishers is no longer "will AEO matter?" but "how do we get cited?"
We're running a live AEO experiment on yositeup.com, documenting every step publicly: methodology, baseline data, strategy adjustments, and results as they come in. This is Part 1.
AEO in the US: The Stakes in 2026
The AI Mode growth story. Google AI Mode grew from 1,600 to 38.2 million monthly US visits in 2026. For publishers, that 12x growth represents a new traffic channel that traditional SEO doesn't capture.
Perplexity's US dominance. Perplexity is particularly strong among US tech, business, and research users. Sites consistently appearing in Perplexity citations report 15-30% incremental referral traffic.
ChatGPT Search adoption. OpenAI's search integration means ChatGPT is now used for queries like "best SEO tools 2026," "how to do technical SEO," and "what is AEO" - queries with clear commercial or informational intent.
For US publishers: AI search is not a future trend. It's the current reality. AEO is the practice of optimizing for it.
Our Methodology for the US Market
Measurement Approach
- Google Search Console - impressions, clicks, position changes
- Perplexity - manual citation checks for 20 target queries (English only for this tracking)
- ChatGPT Search - mention verification across target query set
- Google AI Overviews - presence documentation with screenshots
- GA4 - AI referral traffic tracking
Fan-Out Testing (US English Focus)
Target queries for Google Preferred Sources (EN):
- «what is Google Preferred Sources»
- «how to use Google Preferred Sources for SEO»
- «Google Preferred Sources impact on CTR»
- «should I add my site to Google Preferred Sources»
Experiment Period: May - August 2026
Baseline Data for the US Market
AI visibility before AEO optimization (May 2026):
| Tool | Citations from 20 EN Queries |
|---|---|
| Google AI Overviews | 0 of 20 |
| Perplexity | 0 of 20 |
| ChatGPT Search | 0 of 20 |
Organic baseline: +18% traffic growth in April 2026 (GSC). Strong traditional SEO foundation; now testing the AI layer.
AEO Optimization Tactics for the US Market
Direct answer in the first 150 words. US AI Mode users expect immediate answers. We structure every article with a direct response to the article's core question within the opening paragraph.
FAQ Schema with US-relevant question formulations. Questions are phrased the way US users actually ask them - conversational, direct, often including "how to," "what is," "why does."
E-E-A-T signals for US competitive niches. The US market has the highest E-E-A-T bar for AI citations - especially in YMYL-adjacent topics (SEO tools, marketing advice). We cite authoritative sources (Google, Semrush, Ahrefs research).
Structured data. FAQ Schema, Article Schema, BreadcrumbList across all English versions.
US-Specific AEO Opportunities
Multilingual content advantage. yositeup.com publishes in 10 languages. For US queries in less-covered languages (Russian, Ukrainian, Polish), the AEO citation bar is dramatically lower than for English. We track both.
Speed to citation for non-EN US queries. We hypothesize that Russian-language AI citations in US search will appear faster due to near-zero competition - and will generate data about the relationship between competition level and AEO pickup time.
FAQ
What is AEO (Answer Engine Optimization)?
AEO is the practice of optimizing content to earn citations in AI search engines: ChatGPT, Perplexity, Google AI Mode, Gemini. The goal is to be the source AI uses when answering questions - not just to rank in traditional results.
Why is the US market critical for AEO testing?
The US has the highest AI search adoption: 38.2M monthly Google AI Mode visits, 50M+ Perplexity users, widespread ChatGPT Search usage. If AEO principles work, the US market will show it first and most clearly.
How is AEO measured for a US publisher?
Manual citation checks in Perplexity, ChatGPT Search, and Google AI Overviews. Tracking AI referral traffic in GA4. Monitoring GSC impressions for queries with AI Overviews. We document each check with screenshots and publish results.
Does AEO compete with or complement traditional SEO in the US?
Both. US publishers see that strong traditional SEO rankings don't guarantee AI citations - and AI citations don't always correlate with traditional rankings. AEO optimization reinforces E-E-A-T signals that help both channels, but requires additional specific tactics (direct answers, FAQ schema, definitions).
What's the expected timeline for first AEO citations for a US-facing site?
For already-indexed EN pages: 4-8 weeks based on Clearscope and industry data. New publications: 6-12 weeks. The US market has high competition, which may extend the timeline compared to less competitive markets.
