AEO vs SEO vs GEO: What's the Difference and Which Do You Need?
SEO, AEO and GEO compared in plain English: what each one optimises for, how they overlap and how to combine them to win Google, AI Overviews and ChatGPT.
Key takeaways
- SEO earns rankings, AEO earns direct answers, and GEO earns mentions inside AI-generated responses.
- All three reward clear, accurate, well-structured content from trustworthy sources.
- AEO is about formatting: concise answers, question headings, lists, tables and FAQ sections.
- GEO is about your entity: consistent facts and third-party corroboration across the web.
- Most businesses should run one integrated plan rather than three separate projects.
The short answer
- SEO (search engine optimization) helps your pages rank in search results like Google and Bing.
- AEO (answer engine optimization) helps your content get chosen as the answer, in Google AI Overviews, featured snippets, People Also Ask and voice assistants.
- GEO (generative engine optimization) helps AI models such as ChatGPT, Gemini, Claude and Perplexity understand and recommend your brand in the answers they generate.
Think of it as three questions: Can people find my page? (SEO) Is my page the answer? (AEO) Does AI recommend my business? (GEO)
Side-by-side comparison
| SEO | AEO | GEO | |
|---|---|---|---|

| Key metric | Rankings, clicks | Answer placements | Share of AI mentions |
What AEO looks like in practice
AEO is mostly about how you format information:
- Use real questions as headings. "How much does a root canal cost in Hyderabad?" beats "Pricing".
- Answer in the first 40 to 60 words under the heading. Make it factual and self-contained.
- Then expand with detail, exceptions and examples.
- Use lists for steps and tables for comparisons. Search engines extract these easily.
- Add a genuine FAQ section and mark it up with
FAQPageschema.
Note that since 2023 Google shows FAQ rich results only for a small set of authoritative government and health sites. FAQ schema still helps machines parse your content, so it remains worth adding.
What GEO adds on top
AEO optimises a page. GEO optimises your brand's footprint across the web. AI models synthesise many sources, so they need to see the same facts about you repeatedly from places they trust:
- Consistent name, description and contact details on every profile

- Mentions in industry lists, news, podcasts and expert roundups

Which one do you need?
All three, in proportion:
- Local service businesses: prioritise local SEO and Google Business Profile, then AEO-style FAQs on service pages. GEO follows naturally from consistent listings and reviews.
- B2B and professional services: SEO and content first, with AEO formatting on every article, and digital PR for GEO.
- SaaS and ecommerce: comparison and buying-guide content (great for AEO and GEO) on top of strong technical SEO.
One integrated workflow
- Research the questions buyers ask (search data, sales calls, People Also Ask).
- Map each question to a page.
- Write answer-first, scannable content with schema.
- Build authority with links and mentions.
- Measure rankings, answer placements and AI mentions monthly.
That single workflow covers SEO, AEO and GEO at once.
