What’s the difference between GEO and SEO?
GEO and SEO share much of the same groundwork, but they target different search experiences. This guide explains where they overlap, how their measurements differ, and which approach fits your visibility problem.
Sarah RiceEditor21 September 2026Last reviewed6 minReadKey takeaways
- GEO and SEO share much of the same groundwork, including crawlable websites, clear content and trustworthy third-party coverage.
- SEO focuses on visibility in search results. GEO focuses on getting a business included in written answers from AI systems.
- GEO results can be harder to measure because AI answers may offer only a handful of recommendations, rather than a page of ranked results.
- You may not need a separate GEO agency. An experienced SEO or digital PR agency might already have the skills to add this work.
Where SEO and GEO overlap
SEO and GEO share much of the same groundwork. Both depend on a website that search systems can crawl, understand and trust.
That means technical access still matters. Your pages need clear structure, useful content and information that supports the claims you make. Agencies may also work on digital PR, content and the wider information available about your brand.
The overlap is visible in agency teams, too. Six of the twenty agencies in our review list at least one role with AI search, AEO or GEO in the title. Every one of those titles also mentions SEO.
That matters when you are choosing who to work with. An SEO agency may already have much of the knowledge and infrastructure needed to support GEO. The question is whether its team measures AI visibility separately and has experience improving how brands appear in generated answers.
The differences that matter
The work overlaps, but the buying question changes. SEO competes for positions on a results page. GEO competes for inclusion in an answer, so you need different targets and a different way to check progress.
| What you are comparing | SEO | GEO |
|---|---|---|
| What you are optimising | A page matched to a query with known search demand. | A brand and the information about it across the questions people ask in their own words. |
| What counts as success | A ranking on a results page and the traffic it brings. | Being named or cited inside an answer, and how often that happens across a defined prompt set. |
| How it is measured | Search Console, rank trackers and analytics. | Repeated prompt sets run through the relevant AI engines. Seven of the twenty agencies name their measurement tool, with nine different tools named between them. |
| How quickly it moves | Once a page is crawled, changes can show in days or weeks. | Live retrieval can change within weeks, while a model's broader understanding of a brand can move over a longer period. |
| Who usually owns it | An in-house search team or an SEO agency. | Often the same people. Six of the twenty agencies have a job title mentioning it, always alongside SEO. |
| What goes wrong | Algorithm updates can shift rankings, which you will see in a ranking report. | A model can leave the brand out or describe it inaccurately, and a traditional ranking report will not explain why. |
Where they genuinely differ
The unit you compete for
SEO usually competes at page level. You create a page for a query with known search demand, then aim for a strong position in the results.
GEO competes at brand level. The aim is to make the business, and the information about it, easy for AI assistants to recognise and use.
Questions in place of keywords
SEO starts with keywords and search volumes. GEO starts with the questions people ask in their own words.
That means the work covers more variations of the same problem, including the way someone might ask an AI assistant for advice.
What gets extracted
A search engine usually sends someone to a page. An AI assistant may extract a statement, answer or fact from several sources and present it in a response.
GEO therefore depends on clear information that an assistant can understand, quote or summarise accurately.
Consensus off your own site
SEO can often make progress through work on your own site. GEO also depends on how your business appears across independent coverage and other sources.
AI assistants look for consistent information about a brand. That makes digital PR, reviews and accurate business details part of the visibility work.
What this means if you are buying
Start with the problem you need to solve, then decide which work belongs in the brief.
SEO is usually the priority when you need more qualified visits from search results, stronger visibility for specific queries, or improvements to a particular URL. GEO matters when customers use AI assistants for research and you want your brand considered, recommended or cited in the answer.
The two programmes often share technical and editorial work. That makes it worth checking whether your existing SEO agency can handle GEO properly before appointing another supplier. Ask for evidence of AI-search work, rather than accepting a new label for familiar services.
A useful GEO brief should explain:
- Which AI assistants the agency will track
- Which prompts it will monitor
- How it will measure changes in visibility
- How the findings will sit alongside your existing SEO reporting
- Which technical, content or digital PR work it expects to carry out
Take care with reporting. Search rankings and organic traffic offer familiar reference points. AI visibility can involve how often your brand appears, where it appears, whether the answer cites your site, and which competitors appear instead. Your agency should define those measures before the work begins.
You may also need to change how you judge results. A GEO programme can support brand visibility during research, even when the user does not click through immediately. That makes the buying decision more involved than comparing two keyword ranking reports. Ask the agency to connect its measures to your commercial goals, then check that the proposed prompt set reflects the questions your buyers ask.
FAQ
FAQs
Do I need separate GEO and SEO suppliers?
No. Keeping GEO and SEO with one supplier often makes sense because the work shares technical SEO, content structure and digital PR.
A separate GEO specialist may suit you if your current agency cannot measure AI visibility or explain how it will improve it. Splitting the work between suppliers can also create handovers and gaps, so ask who owns the overall plan.
Can my current SEO agency do this?
Yes, provided it can show relevant capability and measurement.
Ask your agency how it handles technical SEO, content architecture and independent coverage. Then ask how it reports AI visibility. Organic traffic and rankings alone will not show how often your brand appears in AI answers.
Useful reporting may include mention rate against a defined prompt set, citations by URL and entity accuracy.
Is GEO just a rebrand of SEO?
No. GEO and SEO share much of the groundwork, but they focus on different search outcomes.
SEO aims to improve your visibility in search results. GEO aims to place your brand inside written answers from AI assistants. That changes what you measure and how you assess progress.
Can optimising for GEO hurt my search rankings?
Good GEO work should support the foundations that SEO relies on, including a crawlable site, clear structure and useful content.
Ask an agency to explain the changes it recommends before work begins. Check that its reporting covers both organic search performance and AI visibility. That gives you a clearer view of any trade-offs.
What should I do first?
Start by checking what your current SEO agency measures and whether it can assess your AI visibility.
Then ask for a defined prompt set, mention-rate reporting and citations by URL. If your agency cannot explain how it handles technical SEO, content structure and digital PR, compare it with a GEO specialist.
