Generative Engine Optimization (GEO) vs SEO: How to Get Cited in ChatGPT, Perplexity and AI Overviews
What generative engine optimization is, how it differs from SEO and AEO, and the steps to get your brand cited in ChatGPT, Perplexity and Google AI Overviews.
Quick answer
SEO earns rankings in search results, AEO earns featured snippets and direct answers, and GEO earns citations inside AI-generated answers from ChatGPT, Perplexity, Gemini and Google AI Overviews. All three rely on fast, well-structured pages and real authority. GEO adds answer-first summaries, comparison tables, consistent entity data and mentions on the third-party sources AI models trust.
Your buyers still search on Google. But more and more of them also ask ChatGPT, Perplexity or Gemini for recommendations before they ever visit a website. If those answers do not include you, you are invisible at the moment of decision.
What is the difference between SEO, AEO and GEO?
SEO wins rankings, AEO wins direct answers, and GEO wins citations inside AI-generated responses.
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in search results | Win snippets and voice answers | Be named in AI answers |
| Where | Google, Bing results pages | Featured snippets, voice assistants | ChatGPT, Perplexity, Gemini, AI Overviews |
| Key tactics | Technical SEO, content, links | Concise answers, FAQ structure | Entities, answer-first blocks, citations |
| Measured by | Rankings, traffic, leads | Snippet wins | AI share of voice |
How do AI assistants decide which brands to cite?
They favour sources with clear, consistent, verifiable information that other trusted sources confirm. That means well-structured pages, unambiguous facts about who you are and what you do, and mentions in directories, reviews and industry roundups.
How do you optimise your website for AI search?
Make your most important pages easy to quote. Three patterns help most:
1. Open with an answer-first summary
Start key pages with a 50 to 75 word summary that states exactly what you offer, for whom, where and how you deliver it.
2. Use comparison tables
Tables of pricing, timelines and deliverables are easy for both people and models to parse.
3. Phrase headings as real questions
Mirror how buyers ask, such as "How long does SEO take to work?", and answer in the first sentence.
Why do entities and schema matter for GEO?
Because AI systems connect facts to entities. Consistent organisation, service and person data, expressed in schema markup and repeated accurately across your profiles, helps models understand that your brand is a real, specific business with specific expertise.
Why are third-party mentions so important?
AI answers draw heavily on sources beyond your own website: review platforms like Clutch and GoodFirms, industry directories, news coverage and "best of" roundups. Complete, accurate profiles and genuine editorial mentions raise the chance you are included.
What does a GEO audit include?
A GEO audit tests dozens of buyer prompts across AI assistants, records which brands appear and why, reviews your schema and entity consistency, and produces a prioritised plan of content and citation fixes.
Where should you start?
Ask the AI assistants your buyers use the questions they would ask, and see who gets recommended. Then fix your most important pages first. If you would like help, we offer a free AI visibility check. Explore our GEO service and SEO services.

Frequently asked questions
What is generative engine optimization?
Generative engine optimization (GEO) is the practice of structuring your content, brand data and third-party mentions so AI systems like ChatGPT and Perplexity understand, trust and cite your brand in their answers.
Is GEO replacing SEO?
No. GEO builds on SEO. AI answers often draw on pages that already rank well and on trusted third-party sources, so strong SEO remains the foundation.
How do I know if AI assistants mention my brand?
Ask the main AI assistants the questions your buyers ask and record which brands they recommend. A structured audit repeats this across dozens of prompts and tracks changes over time.
