SEO, AEO and GEO are often presented as three separate programs. They are overlapping ways to look at the same website and its answers. Here is where the terms help—and where they do not.
What Do SEO, AEO and GEO Mean?
| Term | Useful meaning | Question it emphasizes |
|---|---|---|
| SEO — search engine optimization | Helping search systems understand a useful website and helping people find it. | Can the right person discover and use the page? |
| AEO — answer engine optimization | An industry label for making accurate answers available to answer-oriented products. | Does this page answer the question clearly and completely? |
| GEO — generative engine optimization | An industry and research label for visibility and representation in generated answers. | Can an AI answer find, use or cite reliable information? |
These are working definitions, not three official algorithms. An answer-oriented feature need not generate a new AI response: a conventional featured snippet is also an answer surface. SEO fundamentals cover discovery and usefulness; our AEO guide goes deeper on question ownership, and the GEO introduction covers generated answers.
Where Do the Terms Overlap?
All three benefit from pages people can reach, read and verify. A direct answer is useful, but it needs enough detail to help someone decide what to do next.
Imagine a Malaysian phone-repair business. A customer asks whether a screen-replacement price includes the part, labour and any warranty. The service page should state its actual terms, supported models, inspection conditions and how to get a current quote. Ordinary search might list it; an answer interface might summarize it; a generated answer might link to it. None of those appearances is guaranteed.
It would not help to publish separate “SEO”, “AEO” and “GEO” versions of that service page. The customer has one decision, and the business should maintain one authoritative answer.
Where Does the Distinction Matter?
SEO is the broad foundation: access, content, page relationships and what happens after a click. AEO highlights the answer: does the right page answer the question accurately? GEO highlights generated responses: might a product use or cite the information when assembling an answer? A mention, a citation and a website visit are different observations.
The boundaries are loose. AEO and GEO are not standardized product settings, and a vendor's score is not a Google ranking metric. The original GEO research measured visibility within a defined generative-answer benchmark. Its results do not establish a universal citation formula for live products.
Does Google Treat GEO as Separate From SEO?
No. Google says its AI Overviews and AI Mode use core Search systems and that optimizing for those generative features is still SEO. To be eligible as a supporting link, a page must be indexed and eligible for a Search snippet. That does not guarantee an AI appearance or a click. Google also says its Search features do not require special AI markup or an llms.txt file.
Other products can have different access rules. OpenAI, for example, separates OAI-SearchBot for ChatGPT search from GPTBot for content that may be used to train models. Do not apply a Google-specific rule to every AI answer product. Our AI search introduction explains that product distinction before platform-level work.
What Should a Website Owner Do First?
- Choose one customer question. Use a real service, product or decision, not an invented list of prompts.
- Find the owning page. Improve it before creating another URL for a new acronym.
- Check the answer and evidence. State scope, limits, current facts and a useful next step.
- Check access for the products that matter. Start with ordinary search eligibility, then inspect platform-specific controls if relevant.
- Measure different outcomes separately. Search visibility, an AI mention, a source link, a visit and an enquiry are not interchangeable.

Frequently Asked Questions
Is SEO Replaced by AEO?
No. AEO emphasizes direct, accurate answers, while SEO covers the broader work of making useful pages accessible and discoverable. Google treats optimization for its AI Search features as SEO.
Is AI SEO Called GEO?
Sometimes. GEO is a common industry term for visibility in generated answers, but it is not the official name of every AI search system. For Google Search, the underlying work remains SEO.
Do I Need Separate SEO, GEO and AEO Pages?
Usually not. Keep one page for one customer task, and use the terms to decide what to inspect. Split pages only when the audience question or required answer is meaningfully different.
