AI & Search
AI-powered search is rewriting how customers discover businesses. AI referral traffic to websites surged 527% in 2025. If your site isn't AI-readable, you're already invisible to a rapidly growing audience.
ChatGPT now has 900 million weekly active users. Perplexity processes 780 million queries a month. Google AI Overviews appear on 1-in-4 searches. When someone asks an AI chatbot "who is the best contractor near me?" or "what web designer should I hire?" — does your business get mentioned?
1. The AI Crawlers Visiting Your Site Right Now
Behind every AI chatbot is a fleet of web crawlers that visit websites and collect content. Right now, at least 15 different AI company bots are crawling the web. The major ones:
- GPTBot / OAI-SearchBot / ChatGPT-User — OpenAI's three crawlers for training, search indexing, and real-time browsing
- ClaudeBot / Claude-SearchBot — Anthropic's crawlers for Claude's knowledge and search features
- PerplexityBot — Powers Perplexity.ai's real-time answer engine
- Google-Extended — Google's opt-out token for Gemini AI training
- Meta-ExternalAgent — Meta's AI crawler, surged to 19% of AI traffic in 2025
Critical: Most AI crawlers — including GPTBot, ClaudeBot, and PerplexityBot — cannot execute JavaScript. They only read raw HTML. If your site is built entirely in React or Vue without server-side rendering, AI bots may see a blank page.
2. Traditional SEO vs. AI SEO: What's Different
If you've been optimizing for Google, that's a great foundation — but AI search operates by different rules.
| Traditional SEO (Google) | AI SEO / GEO (ChatGPT, Perplexity) |
|---|---|
| Ranks 10 blue links | Generates 1 synthesized answer citing 2–7 sources |
| Optimizes page-level keywords | Optimizes extractable facts and passages |
| More backlinks = better ranking | More brand mentions across the web = better citation rate |
| Keyword stuffing can help | Keyword stuffing HURTS AI performance |
| Distance matters for local results | Relevance & authority matter more than proximity |
| Page traffic is a signal | Traffic correlates negatively with AI citations (Profound, 2025) |
3. Generative Engine Optimization (GEO)
Researchers at Princeton, Georgia Tech, and the Allen Institute for AI formally defined GEO — Generative Engine Optimization — as the practice of making your content extractable and citable by AI answer engines. Their study of 10,000 queries found GEO techniques can boost AI visibility by up to 40%.
The most effective GEO techniques, ranked by impact:
- Add citations from credible sources inside your content → +115% visibility boost
- Include specific statistics every 150–200 words → up to +40% improvement
- Write with authoritative, confident tone (avoid hedging) → consistent citation gains
- Include expert quotations with real attribution → +37% on Perplexity specifically
- Improve sentence clarity and structure → +15–30% across all platforms
4. How Each AI Platform Chooses Its Sources
ChatGPT ChatGPT leans on encyclopedic, factual content. Wikipedia is its #1 source (7.8% of all citations). 87% of its web citations match Bing's top 10 results. It favors branded vendor websites and older, established content.
Perplexity Perplexity favors community-vetted, recent content. Reddit is its top source (6.6%). It strongly prefers content published within 90 days and question-format headlines.
Google AI Overviews Google AI Overviews correlates with traditional SEO rankings — but 47% of its citations come from pages ranking below position 5. Semantic completeness (fully answering a query in 134–167 word self-contained passages) showed the strongest citation correlation (r=0.87).
Universal insight: Brand mentions — not backlinks — are the #1 factor for AI visibility across all platforms. Brands in the top 25% for web mentions receive 10x more AI citations than those in the next quartile. (Ahrefs, 75,000 brands study, December 2025)
5. Your AI Visibility Action Plan
Here is a prioritized checklist for small business owners to become AI-visible in 2026:
Step 1: Check your robots.txt. Make sure it does NOT block GPTBot, OAI-SearchBot, ClaudeBot, or PerplexityBot. Blocking these prevents your site from appearing in AI search results.
Step 2: Fix JavaScript rendering. If your site runs on React, Next.js, or Vue without server-side rendering, AI crawlers may see nothing. Enable SSR or generate static HTML.
Step 3: Restructure content for AI extraction. Lead every page with a direct answer in the first 40–60 words. Use question-format headings. Include specific statistics every 150–200 words. Add FAQ sections. Remember: 44% of all AI citations come from the first 30% of a page — front-load your key info.
Step 4: Implement Schema Markup. Google, Microsoft, and OpenAI all confirmed they use Schema.org structured data for AI features. Implement JSON-LD schema for LocalBusiness, FAQPage, Service, and Review. Websites with proper schema are cited 3.2x more often.
Step 5: Build brand mentions everywhere. Fully optimize your Google Business Profile. Create profiles on Yelp, Trustpilot, and industry directories. Get active on Reddit and Quora. Brands on Wikipedia + Reddit + review sites get 2.8x higher AI citation rates.
Step 6: Keep content fresh. AI systems strongly prefer recent content — 65% of AI bot hits target content published within the past year. Update your core pages quarterly. Add visible "Last Updated" timestamps.
Step 7: Consider adding llms.txt. A new file at yourwebsite.com/llms.txt gives AI systems a Markdown-format summary of your key pages. Companies like Anthropic, Stripe, and Zapier already use it.
The bottom line: AI search is not replacing Google overnight — but it's growing fast, converting visitors at 5x higher rates, and rewarding businesses that optimize early. The practices that make your site AI-readable also make it a better website for humans. Start now.
