In the US market, search behavior has shifted more dramatically than anywhere else. SparkToro's analysis of 41 platforms reveals a landscape where Amazon captures 63% of product searches, TikTok is Gen Z's primary information source, Reddit dominates AI-generated answers, and Google AI Mode has 38.2 million monthly users.
For US publishers and SEO specialists: the multi-platform search reality is most pronounced in the United States. Understanding it is no longer optional.

Four US-Specific Trends from SparkToro Data
1. Amazon has taken product search from Google. In the US, 63% of product searches now start on Amazon - not Google. For e-commerce clients operating in the US, Amazon SEO is a separate discipline with its own algorithms, review signals, and ranking factors.
2. TikTok is Gen Z's first search destination. 40% of US Gen Z users regularly use TikTok for informational searches. Beauty, fitness, food, travel, finance - these categories are losing younger audiences from Google to TikTok at measurable rates.
3. Reddit dominates AI-generated answers. US users trust real Reddit experiences. AI search engines (Perplexity, ChatGPT, Google AI Mode) have learned this trust signal - Reddit citations grew 450% in AI responses in 2026. For US SEO, relevant subreddit presence is now an AI citation strategy.
4. AI search is mainstream in the US. Google AI Mode (38.2M monthly US visits), Perplexity (50M+ users), ChatGPT Search - this is active US traffic, not a future trend. AEO optimization is the practice for capturing it.
US Publisher Strategy: Where to Focus
For English-language publishers in the US
The US market has the highest AI search adoption and the highest English-language AEO competition. Getting cited in English requires:
- Strong E-E-A-T signals (Google's highest standards apply)
- DR 30+ for most competitive niches
- FAQ Schema + direct-answer structure
- Authoritative data citations (Google research, Semrush studies, Ahrefs data)
For multilingual publishers in the US
Non-English US search segments are nearly open. Russian-language queries from US users have near-zero AI citation competition, despite 1M+ Russian-speaking digital users in the US. The same applies to Ukrainian and Polish diaspora communities.
This creates an unusual opportunity: establish AI citation authority in non-English US segments first (2-4 weeks), then use that foundation to build English-language authority (4-8 weeks).
AI Aggregation: Why Multi-Platform Matters
When Perplexity answers a query about your topic, it draws from:
- Traditional websites (your site, competitors)
- Reddit discussions
- YouTube content
- Pinterest boards
- LinkedIn articles
Multi-platform presence isn't about being everywhere - it's about being present in the specific platforms AI engines pull from for your niche. For US SEO topics: Reddit + YouTube + authoritative blog content is the AEO citation stack.
FAQ
How has search behavior in the US changed in 2026?
Amazon captures product searches (63% start there), TikTok is Gen Z's first stop for informational queries, Reddit dominates AI-generated answers (450% growth in citations), and Google AI Mode has 38.2M monthly US users. Google remains the largest single search destination but is no longer the only one that matters.
Should US e-commerce clients prioritize Amazon or Google SEO?
Both - but for different query types. Google captures informational and brand searches. Amazon captures purchase-intent queries for existing product categories. The split depends on the client's category and funnel position.
Does TikTok impact US B2B SEO?
Minimally for B2B. TikTok's search impact in the US is concentrated in B2C, younger demographics, and visual niches. For B2B and professional services, LinkedIn, YouTube, and Reddit carry more SEO-adjacent weight.
What is the fastest path to AI citations for US publishers?
Non-English US content has near-zero AI citation competition (2-4 weeks to first citations). For English content: structured direct answers + FAQ Schema + authoritative data citations in the first 150 words. Expected timeline: 4-8 weeks for indexed pages.
