When someone asks ChatGPT "Who's a good dentist near me that takes walk-ins?" there's no page two. The AI writes a short answer, names a few practices, and moves on. If your business isn't in that answer, you're effectively invisible to that customer.
Generative Engine Optimization (GEO) is the work of changing that. Here's what it is, how it differs from SEO, and what you can actually do about it.
What is GEO (Generative Engine Optimization)?
GEO is the practice of improving how often, how accurately and how favorably generative AI tools mention your business in the answers they write. The target isn't a ranking position; it's being named, described correctly and recommended.
"Generative engines" are AI systems that write new text in response to a question. Examples include ChatGPT, Gemini, Claude, Microsoft Copilot, Perplexity and Google's AI Overviews and AI Mode. Instead of showing a list of websites, they compose an answer, sometimes with source links and sometimes without.
The term "Generative Engine Optimization" comes from a 2023 academic paper and has since been adopted widely by marketers. For a short definition, see our GEO glossary entry.
How is GEO different from SEO?
SEO optimizes a page to rank in a list of links; GEO optimizes your whole business presence so an AI includes and recommends you in a written answer. SEO is page-focused. GEO is brand-and-entity-focused.
| SEO | GEO | |
|---|---|---|
| Where you show up | Search results pages (Google, Bing) | Inside AI-written answers (ChatGPT, Gemini, Perplexity, AI Overviews) |
| What "winning" looks like | A top-ranked link and a click | Being named, described accurately and recommended |
| Main focus | Individual pages and keywords | Your business as an entity, across the whole web |
| Key signals | Relevance, links, technical health, user experience | Everything in SEO, plus consistent facts, third-party mentions, reviews, clear and summarizable content |
| How you measure | Rankings, clicks, impressions | Mentions, citations, accuracy of descriptions, leads who say "AI told me" |
| Control | Moderate (you control your pages) | Lower (the AI synthesizes many sources) |
The biggest mindset shift: in GEO, what other sites say about you can matter as much as what your own site says. An AI writing a recommendation is often, in effect, summarizing what the web says about your business.
How do generative AI tools decide which businesses to mention?
AI tools generally combine what they learned in training with information retrieved from the web at the time of the question, then summarize the sources that look most relevant and credible. The exact logic is proprietary and varies by tool, so no one can give you a precise formula.
What's reasonable to say, based on how these systems are publicly described:
Training data vs live retrieval
- Training data is the large body of text a model learned from. It's a snapshot in time. If your business was barely mentioned online before a model's cutoff, the model may know little about you.
- Live retrieval (sometimes called "grounding" or web search) happens when the tool searches the web while answering. This is how ChatGPT search, Perplexity and Google's AI features can cite current pages. For local and "best near me" questions, retrieval usually matters more, because the AI needs current details like location and hours.
Signals that plausibly matter
Since the tools are summarizing what they find, the following tend to help:
- Clear, consistent facts about your business (name, services, location, hours) across your site, Google Business Profile and directories.
- Third-party corroboration: reviews, directory listings, local news, chamber of commerce pages, industry associations, supplier "find a dealer" pages.
- Content that directly answers questions in plain language, so it can be summarized without distortion.
- Specificity: service areas, specialties, credentials, and what kind of customer you serve best.
- Crawlability: if AI crawlers or search engines can't access your pages, they can't use them.
This is closely related to entity SEO: helping machines understand that your business is one specific, well-defined thing with known attributes.
What does GEO look like for a small business in practice?
For most small businesses, GEO means tightening your business facts, earning more and better mentions around the web, and publishing content that makes it easy for AI to describe you accurately. It's practical, not mysterious.
Here's an illustrative example. Imagine two HVAC companies in the same town.
- Company A has a five-page website with a slogan and a phone number, a Google Business Profile with outdated hours, and a handful of reviews from years ago.
- Company B has service pages that explain exactly what they do ("heat pump installation," "same-day AC repair," "maintenance plans"), lists its service area by town, keeps its profile current, gets a steady stream of detailed reviews, and is listed by its equipment manufacturer and the local chamber of commerce.
When someone asks an AI "who installs heat pumps in [town]?", Company B has given the AI far more to work with. Nothing guarantees Company B gets named, but it's much better positioned. If you run an HVAC business, our AI for HVAC companies guide and HVAC industry page show how this fits with the rest of your operations.
A GEO action list
- Audit what AI says now. Ask ChatGPT, Gemini, Perplexity and Google your customers' key questions. Write down who's mentioned and whether anything about you is wrong.
- Fix the facts at the source. Update your Google Business Profile, Bing Places, Apple Business Connect, Yelp and your main industry directories so they match your website exactly.
- Write an "about" page that defines you. Who you serve, what you do, where, since when, credentials, and what makes you different, in plain sentences an AI can summarize.
- Build service pages that answer real questions, using answer-first structure (see what is AEO?).
- Earn mentions. Sponsor a local event, get listed by suppliers and associations, contribute expert quotes to local media.
- Grow detailed reviews. Ask customers to mention the specific service and town. Review automation keeps the requests consistent without you chasing anyone.
- Re-check monthly. AI answers change and vary from one session to the next, so look for trends rather than single results.
What are the limits of GEO?
GEO improves your odds; it doesn't give you control. AI tools can be inconsistent, can make mistakes, and change how they work without notice.
Be realistic about a few things:
- Answers vary. Ask the same question twice and you may get different businesses. Track patterns over time.
- Measurement is immature. There's no equivalent of Google Search Console that shows every AI mention. You'll rely on manual checks, referral traffic from AI tools where it's visible in analytics, and asking new customers how they found you.
- Errors happen. AI tools sometimes state outdated or wrong information. The best defense is accurate, consistent information everywhere the AI might look.
- No one can sell you guaranteed placement in organic AI recommendations. Treat that claim as a red flag.
Should a small business focus on SEO or GEO?
Do both, in the right order: fix the SEO foundations first, then layer GEO on top. GEO built on a broken website is unlikely to work well, because many AI tools retrieve from the same web that search engines index.
| Your situation | Where to start |
|---|---|
| Outdated, slow or hard-to-edit website | Website refresh with clean structure and schema |
| Decent site, inconsistent listings, few reviews | Entity cleanup plus review automation |
| Solid site and reviews, but not mentioned by AI tools | Answer-first content, third-party mentions and AEO & GEO work |
| Getting AI mentions but missing the calls they generate | An AI receptionist so new leads always reach a person or a fast reply |
That last row matters more than people think. Being recommended by an AI is only valuable if the customer can reach you. If they call and hit voicemail, they may simply ask the AI for the next option.

Key takeaways
- GEO is about being mentioned and recommended inside AI-written answers, not just ranking as a link.
- It's entity-focused: what the whole web says about your business matters, not just your own pages.
- AI tools mix training data with live web retrieval, so both your long-term reputation and your current online facts count.
- Consistent facts, third-party mentions, detailed reviews and clear content are the practical levers.
- GEO sits on top of SEO. Fix your site foundations first.
- No one controls AI answers. Track trends monthly and be skeptical of guarantees.

FAQ
Frequently asked questions
What does GEO mean in marketing?
GEO stands for Generative Engine Optimization. It's the work of improving how generative AI tools, like ChatGPT, Gemini, Perplexity and Google AI Overviews, describe, mention and recommend your business. It focuses on what the AI says about you, not just where a page ranks.
Is GEO the same as AEO?
They overlap a lot but emphasize different things. AEO focuses on making your pages easy to quote as a direct answer, while GEO focuses on how AI-generated responses mention and recommend your brand overall. Most small businesses should work on both together because the same foundations support each.
Does GEO replace SEO?
No. Many AI tools retrieve information from the web or from search indexes, so pages that are crawlable and trusted in search still matter. GEO adds new priorities on top of SEO, such as consistent entity information, third-party mentions and content written to be summarized accurately.
Can I pay to be recommended by ChatGPT?
There is no simple way to buy organic recommendations inside AI answers, and you should be skeptical of anyone selling guaranteed placement. Advertising products inside AI tools may exist or emerge, but organic mentions depend on what the AI can find and trust about your business. GEO is about improving those underlying signals.
How do I check what AI tools say about my business?
Ask several AI tools the questions your customers would ask, like 'best emergency plumber in [city]' or 'is [your business name] reputable?', and note the answers. Repeat the same prompts monthly, because results vary between sessions and change over time. Look for missing mentions, outdated facts and competitors that show up instead of you.
