AI Search Optimization (GEO, AEO): What It Is, Common Mistakes & How to Win
En corto
AI Search Optimization (GEO/AEO) is the practice of getting your brand mentioned, cited and recommended inside AI-generated answers — ChatGPT, Perplexity, Gemini, Google AI Overviews — instead of only ranking in the classic list of blue links. Traditional SEO gets you ranked; AEO gets you cited inside the answer.
One thing most founders are still ignoring: AEO — Answer Engine Optimization. Traditional SEO gets you ranked in Google. AEO gets you cited inside AI answers (Perplexity, ChatGPT, Google AI Overviews, etc.). The shift is already measurable: roughly 37% of consumers now start searches inside AI tools, and Gartner projects a 25% drop in traditional search volume. If your brand isn't inside the answer, you're invisible to a growing share of buyers.
What is AI Search Optimization?
AI Search Optimization is the umbrella for optimizing how AI engines represent your brand. You'll see it under three names that mean almost the same thing:
| Term | Focus | What it optimizes |
|---|---|---|
| SEO | Search engines (Google, Bing) | Rank position in the link list |
| AEO | Answer engines (assistants, chatbots) | Being inside the answer |
| GEO | Generative engines (LLMs) | Being cited and recommended |
In an AI answer there is no page-two. A model typically names three or four brands. You're either in that set or you don't exist for that query.
How does an AI engine decide who to cite?
Entity coverage
How well the model understands your brand as an entity — what you sell, for whom, pricing, integrations. If the model doesn't 'know' you, it can't recommend you.
Citable sources
Which sites, forums, directories and reviews talk about you with clear data. Models lean on sources: if competitors are in them and you're not, they win.
Clarity and structure
How easy it is to extract an answer from your content — direct answers, concrete data, FAQs, semantic headings, schema.org.
Common mistakes founders make
- 1Measuring once and assuming it holds — AI answers drift 40–60% per month.
- 2Optimizing only their own website and ignoring the third-party sources AI actually cites.
- 3Translating English content instead of creating native content — prompts and cited sources differ by language and country.
- 4Chasing rankings while ignoring sentiment and factual errors (an AI saying 'they closed' costs real customers).
- 5Treating AEO as a one-off project instead of a dashboard you watch.
The costliest mistake
Factual errors. If AI states the wrong price, a dead product, or 'permanently closed', that's not a visibility problem — it's active customer loss. Fix these first by contrasting AI output against a source-of-truth sheet for your brand.
How to optimize for AI search: 5 moves
Measure your baseline
Run 20–30 real category prompts across ChatGPT, Gemini and Perplexity. Record if you appear, at what position, with what sentiment, and which sources are cited.
Close entity gaps
Publish what the model lacks: pricing, use cases, integrations, comparisons, FAQs — clear and structured.
Get into cited sources
Rank your baseline sources by frequency, then earn presence: reviews, directories, community threads, comparison articles.
Make content citable
Answer in the first 150 characters, back it with data, add FAQ + schema, avoid hiding key info behind JavaScript or PDFs.
Monitor continuously
Re-measure weekly. Drift is high enough that a single snapshot expires in weeks.
How Mentio helps
Mentio runs this loop automatically — and it's built native-first for non-English markets (Spanish, Catalan, Italian, French, Portuguese). It measures your Visibility Score and Share of Voice, detects sources and factual errors, and closes every report with a prioritized action plan.
Preguntas frecuentes
What is AI Search Optimization?
It's the practice of optimizing how AI engines (ChatGPT, Perplexity, Gemini, Google AI Overviews) mention, cite and recommend your brand inside their generated answers. It's known interchangeably as AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization).
Is AEO different from SEO?
Yes. SEO optimizes your rank in a list of links; AEO optimizes whether your brand appears inside an AI-generated answer. AEO builds on SEO fundamentals (structure, schema, authority) but measures different things: mentions, sentiment and cited sources instead of rankings and clicks.
What's the biggest AEO mistake?
Ignoring factual errors and the third-party sources AI cites. Many founders optimize only their website and measure once — but AI answers drift 40–60% per month and lean heavily on external sources like forums, directories and reviews.
How do I get cited by ChatGPT?
Give the model clear entity information on your site, earn presence in the sources it cites for your category, make your content directly citable (answer-first, data-backed, schema), and monitor continuously because answers change monthly.
¿Qué dice la IA de tu marca ahora mismo?
Deja de suponer. Mentio lo mide en tu idioma: si ChatGPT, Gemini y Perplexity te mencionan, con qué sentimiento y desde qué fuentes.
