- AI Search changes search: instead of 10 blue links — one synthesised answer
- Google AI Overviews, ChatGPT Search, Perplexity — the three main AI search systems
- For informational queries CTR may drop 20–40%
- Response: optimise to become the source AI cites, not just a page in results
- E-E-A-T and Schema.org are the foundation for AI search visibility
What is AI Search and how it works
AI Search is the next generation of search engines that, instead of a classic list of links, generate a synthesised answer by analysing many sources simultaneously. Leading systems: Google AI Overviews, ChatGPT Search, Perplexity AI, Bing Copilot and Claude.
How it works: user enters a query → AI scans indexed sources → synthesises an answer from multiple sources → displays citations with links. For SEO this is a fundamental shift: ranking in the TOP-10 is no longer enough — you need to be a source AI trusts and cites.
How AI Search affects SEO and traffic
Research shows uneven impact depending on query type:
| Query type | AI Search impact on CTR | Adaptation priority |
|---|---|---|
| Informational ("what is...", "how to...") | -20% to -40% | High — become a citation source |
| Navigational (brand name) | Minimal | Low |
| Commercial ("buy", "price", "best") | -5% to -15% | Medium |
| Local ("near me", "in [city]") | Negligible | Low — Local SEO remains primary |
How to optimise for AI Search
1. E-E-A-T as the foundation of AI trust
AI systems are trained to identify authoritative sources by the same signals as Google: author experience, expertise, domain authority, reliability. Practical steps: detailed author pages with biographies, links to LinkedIn and professional community profiles, content update dates, citations and references throughout articles.
2. Schema.org and content structure
AI reads Schema.org markup to quickly understand context. For citation in AI Overviews especially important: Article, FAQPage, HowTo, Person, Organization. Q&A formatted answers with clear H2/H3 structure significantly increase citation chances.
3. Contextual blocks for AI
Add clear definitions in opening paragraphs ("X is..."), key takeaway blocks, comparison tables, numbered lists with specific steps. AI synthesises answers from clearly structured content far more readily than from continuous prose.

Differences between AI platforms
- Google AI Overviews — favours authoritative sites with GSC indexation and strong E-E-A-T
- Perplexity AI — cites fresh sources, indexes blogs and news sites well
- ChatGPT Search — uses Bing index, domain authority is important
- Claude (Anthropic) — emphasis on safety and source accuracy
Conclusion: SEO in the age of AI
AI Search doesn't cancel SEO — it deepens and enriches it. Sites with strong E-E-A-T, correct Schema.org markup and structured content gain an advantage in both worlds: classical Google ranking and AI citation. Those who adapt now build a compounding competitive advantage as AI Search's share of overall search continues to grow.
