SEO vs AEO vs GEO: What's the Difference?
How search, answer-engine and generative-engine optimization differ — and which your brand needs.
SEO ranks you in the list of search links. AEO (Answer Engine Optimization) gets you cited inside AI answers like Google AI Overviews and ChatGPT. GEO (Generative Engine Optimization) shapes how generative AI describes and recommends your brand. They overlap — and work best run together.
How do SEO, AEO and GEO compare?
| Dimension | SEO | AEO | GEO |
|---|---|---|---|
| Goal | Rank in links | Be cited in AI answers | Shape AI's brand narrative |
| Target | Keywords | Questions & entities | Topics & recommendations |
| Surfaces | Search results | AI Overviews, ChatGPT | Generative assistants |
| Key levers | Links, content, technical | Schema, entities, llms.txt | Authority, sentiment, presence |
| Measurement | Rankings & traffic | Citations & AI share of voice | Mention quality & recommendation |
Why do they work better together?
These disciplines aren't competing — they're layered. Answer engines and generative models are trained and grounded on the open web, so the same authority, crawlability and content quality that drive SEO also make you citable by AI. Investing in one strengthens the others. The brands winning today build a single content and authority foundation that serves search engines and answer engines at once.
