What is an AI search expert?
An AI search expert specializes in Generative Engine Optimization (GEO) — the discipline of optimizing content, entity signals, and citations so a brand shows up in AI search engines like ChatGPT, Perplexity, Gemini, Google AI Overviews, and Claude. AI search experts sit between classical SEO and emerging Answer Engine Optimization (AEO). Their work combines entity clarity, factual density, structured data, and citation-worthy authority.
How is GEO different from SEO?
Classical SEO optimizes for rankings in the traditional blue-link search results page. GEO optimizes for being cited, summarized, or quoted in AI-generated answers. The tactics overlap in some areas (structured data, E-E-A-T, entity optimization) but diverge sharply in others: AI search rewards explicit claim density, question-answer formatting, third-person authority, and broad mentions across the web rather than backlinks to a specific URL.
Which AI search engines matter in 2026?
| Engine | What it does | GEO priority |
|---|---|---|
| Google AI Overviews | AI summaries at the top of Google SERPs | ★★★★★ Highest volume |
| ChatGPT Search | OpenAI's answer engine + citations | ★★★★ Fast-growing |
| Perplexity | Answer engine with inline citations | ★★★★ Cited by power users |
| Gemini | Google's conversational AI | ★★★ Integrated across Google |
| Claude | Anthropic's assistant, often w/ web search | ★★ Enterprise contexts |
What does an AI search expert actually do?
- Visibility audit. Track how your brand currently shows up across AI engines — which queries surface you, which surface competitors, and where you're missing entirely.
- Entity optimization. Clarify your brand entity with consistent Wikidata / Wikipedia / schema.org signals so LLMs can disambiguate you from noise.
- Citation worthiness. Build the kind of content AI engines prefer to cite — explicit claims, high factual density, clear Q&A structure, authoritative tone.
- Distribution layer. Get mentioned across the broader web (press, podcasts, forums, industry publications) so AI crawlers encounter you in multiple contexts.
- Measurement & iteration. Track share-of-voice, sentiment, and citation patterns across engines over time — the loop that separates random SEO from systematic GEO.
How to choose the right AI search expert for your brand
- Operator or consultant? Operators (like Thomas at OtterlyAI) have platform-level data and see patterns across thousands of brands. Consultants bring deep single-client focus.
- Published research or just opinions? The fastest way to filter: ask for their most recent GEO benchmark or research publication.
- Domain fit. B2B SaaS, DTC e-commerce, DevTools, and regulated industries all have different GEO playbooks. Match the expert's background.
- Language and market. GEO is language-dependent. If you're DACH, LATAM, or APAC-focused, local market experience matters.

What is Generative Engine Optimization (GEO)?
GEO is the practice of optimizing content, entity signals, and citations so that a brand is surfaced by generative AI search engines. It's adjacent to classical SEO but emphasizes entity clarity, factual density, structured data, and citation-worthiness over link-building.
Is GEO replacing SEO?
Not replacing — evolving. Classical SEO still drives significant traffic via blue-link results, and most serious GEO practitioners are also strong SEOs. But a growing share of high-intent queries now resolve inside an AI answer — for those queries, GEO is the game.
Which AI search engines should I track?
The five that matter in 2026 are Google AI Overviews, ChatGPT Search, Perplexity, Gemini, and Claude. Tools like OtterlyAI track visibility across all of them in one dashboard.
