GEO vs SEO is a comparison of discovery surfaces and measurement. SEO addresses search visibility and site performance; GEO focuses on the information used in generated answers. They share much of the same content and technical work.

Organize the work around customer questions and concrete deliverables. The label matters less than knowing which surface you are improving and how you will measure it.

## What the terms describe

| Term | Focus |
| --- | --- |
| SEO | Findability and performance in search |
| GEO | Presence and accuracy in generated responses |
| AEO | Usefulness as a source for direct answers |
| LLM SEO | A common label for optimization aimed at model-based systems |

Teams use these terms with different scopes. Define the actual pages, integrations, prompts and reports included in the project.

## The foundations you can share

Clear pages, useful internal links, accurate business details and reliable access support both search and assistant experiences. Content quality remains relevant; serving a new format does not replace answering the customer’s question.

Google’s [AI features guidance](https://developers.google.com/search/docs/appearance/ai-features) retains SEO fundamentals, useful text, visual content and consistent structured data. Use shared sources and keep the experience clear after a visitor follows a link.

## Where the work differs

A generated response can combine multiple sources and answer a question without a visit to your site. A site visit therefore captures only part of the interaction. Prompt sampling can inspect selected answers, while server reporting shows requests that reach your infrastructure.

Direct fetches and browser-based agents have different capabilities. Test the relevant path. Markdown can make a response compact for clients that request it; accessible HTML and useful visual design remain valuable.

## Use separate evidence for separate questions

| Evidence | What it tells you |
| --- | --- |
| Search reporting | Performance within the search product’s reported scope |
| Prompt samples | What specified models answered under specified conditions |
| Server requests | Which reported requests reached your site |
| Referrals and conversions | What identifiable arriving visitors did |
| Content checks | Whether the intended facts are present and consistent |

Document dates, sample scope and the changes made. Compare trends without treating a server request as an answer impression or a format change as proven revenue lift.

## Plan one coordinated improvement program

- Audit the questions, sources and pages that matter most to the business.
- Fix broken access and missing or conflicting facts.
- Add supported formats or integrations where they improve the actual retrieval path.
- Keep content and business listings current.
- Review reported activity and sampled answers, then choose the next useful change.

## Choose help by deliverable

An agency or tool can help with research, content, integration and measurement. Ask which outputs the engagement produces, who maintains them and how you can inspect the evidence. Separate budgets can make sense when they fund distinct work; overlapping labels alone do not define distinct deliverables.

## What is the difference between GEO and SEO?

SEO focuses on search discovery; GEO focuses on generated answers. They share content and technical foundations but require attention to different evidence.

## Can I do both together?

Yes. Maintain clear source information and coordinate page, integration and measurement improvements across both surfaces.

## Is GEO a one-time setup?

No. Setup establishes access and reporting; ongoing changes to products, policies and customer questions create further work.

## What should I measure?

Track source quality, search performance, sampled answers, reported requests and identifiable referrals separately.

## Where does AEO fit?

AEO focuses on serving as a useful source for answers. Define its deliverables alongside the GEO and SEO work your team already does.
