SEO for AI is the work of making your website and business profile easy for tools like ChatGPT, Gemini, Perplexity and Google’s AI Overviews to understand, trust and cite. It also goes by the name GEO, short for Generative Engine Optimization. It doesn’t replace classic SEO, it builds on it. And no one can guarantee your business will be cited, because none of these platforms publishes its selection rules.
If you’ve heard “it’s GEO now, forget SEO,” you can relax. Almost everything that helps an AI cite a business was already good SEO practice. The emphasis changes: answer the whole question, prove who you are and show up outside your own website.
SEO for AI: what GEO is and how it differs from classic SEO
GEO (Generative Engine Optimization) is the set of adjustments that raise the chance of an AI-generated answer using or citing your content. Classic SEO wants your page to appear in a list of results. GEO wants your information to end up inside the answer the AI writes.
In practice, people don’t see ten links. They read a paragraph with two or three sources next to it. If you’re not among those sources, you’re invisible in that conversation, even if you rank first in the traditional list.
| Classic SEO | GEO, or SEO for AI | |
|---|---|---|
| Where you appear | Results list and Google Maps | Inside the answers of ChatGPT, Gemini, Perplexity and Google’s AI Overviews |
| What people see | Title, description and link | A ready-made answer with the source cited |
| Unit of work | The whole page | The passage that answers a question |
| Strongest signal | Useful content, links, page experience | Direct answer, trusted source and mentions on other sites |
| Measurement | Position, clicks, impressions | Citations, referral visits and inquiries |
| Guarantee | None | None |

How ChatGPT, Gemini, Perplexity and Google choose what to cite
None of these companies discloses its formula, so no one outside knows exactly how the selection works. What can be said comes from Google’s documentation and repeated tests: AI tools favor traceable sources, direct answers, well-organized information and a name that shows up consistently in several places.
Traceable source
The AI needs a place to pull information from. A page with an author, an identified company, an address, an update date and data that can be confirmed elsewhere inspires more trust than an anonymous text. Someone who writes “we’re an industry leader” with nothing to back it up loses to someone who writes “serving customers since 2014, at 123 Main Street, with 3 licensed professionals.”
Direct answer
Pages that answer the question right at the start, in one or two sentences, are easy to extract. It’s the question-and-answer format: “How long does installation take? On average, two business days for a home of up to 1,000 square feet.” The AI takes the passage and the reader understands without opening the page.
Structured data
Structured data, or schema, is code that describes the page to machines: who the company is, what its address is, what the frequently asked questions are, what the service is. Google explains the concept in its introduction to structured data. It helps machines understand the content, but it isn’t a citation button.
Mentions on third-party sites
This is the most important change compared to old-school SEO. The AI doesn’t depend only on what you say about yourself. It cross-checks with what directories, review sites, local press, associations and social networks say. A company mentioned in five trusted places with the same details is more likely to be considered than one that only exists on its own site.
Consistent name, address and phone number
If the name changes from one site to another, if the phone shows two different numbers or the address appears abbreviated three different ways, the AI is unsure whether it’s the same company. Consistency of name, address and phone number, the famous NAP, is one of the cheapest and most overlooked fixes.
What Google says about AI features
Google has an official page on AI features in Search, which covers AI Overviews and AI Mode. The key point is that there’s no extra requirement or special optimization to appear there. The page needs to be indexed and eligible to show with a snippet in results, and the content needs to be useful and made for people. In other words, GEO on Google is SEO done well, with more attention to clarity and trust.
The same documentation indicates that clicks from these features are included in Search Console reports. For the local side, where Google is putting AI inside the map, it’s worth reading what Google Ask Maps is and how to prepare your business.
Step-by-step SEO for AI: how to show up in ChatGPT
There’s no sign-up to get into ChatGPT. What exists is a set of steps that makes your business easier to find and cite. This is the roadmap that works for anyone with a business and a standard website, in order:
- List your customers’ real questions. Take the questions that come in on WhatsApp, by phone and at the front desk. “How much does it cost,” “how long does it take,” “do you serve my neighborhood,” “what’s the difference between X and Y.” These are the questions people also ask AI.
- Create a page that answers the whole question. One page per service or per big question, with the answer in the first lines and the details after: timeline, steps, who does the work, what’s not included. Vague text doesn’t get cited.
- Add an FAQ block. Four to six real questions, with short, specific answers, at the end of the page. This format is the easiest for AI to reuse.
- Mark up the page with structured data. Organization, local business, FAQ and service, as applicable. Check it with Google’s Rich Results Test after publishing.
- Complete your Google business profile. Right category, services, hours, real photos and answered reviews. The complete guide to optimizing your Google Business Profile has the checklist. If you still need to understand the basics, see what Google Business Profile is.
- Show up in directories and review sites in your industry. Register the company in a few trusted places, with name, address and phone identical to those on your site and Google profile. A few that are right beat many that are inconsistent.
- Update and sign your content. Review date, the name of the writer and the responsible company. A page left untouched for three years loses to one reviewed this year.
If you complete these seven steps, you’ve done most of the SEO for AI, without buying any tool.
llms.txt: an option, with no guarantee
llms.txt is a text file at the root of the site, proposed by developers, that lists the main pages in a simple format so language models can read them more easily. It’s an interesting idea, cheap to do, and none of the major platforms has confirmed that it uses the file to decide what to cite.
The honest recommendation is this. If your site already has well-written pages, creating the file takes half an hour and does no harm. If your site is still disorganized, the file solves nothing. Put it last in the queue and don’t treat it as a shortcut.
What doesn’t work
Many SEO-for-AI proposals sell something that doesn’t exist. Avoid four things:
- Text written for robots. Repeated sentences, stacked keywords and paragraphs with no human behind them. AI reads natural language very well, and the person who arrives through the link leaves.
- Promising a position in AI. There’s no citation ranking that anyone controls. Anyone promising “first place on ChatGPT” is promising what they can’t deliver.
- Buying mentions in bulk. Fake profiles, paid reviews and unlabeled sponsored text. When the platform detects it, the effect is the opposite.
- Swapping everything for GEO. Abandoning the SEO basics (fast site, indexed page, clear title) pulls the floor out from under everything else.
How to measure whether AI SEO is working
Measuring AI citations is imprecise, and it’s better to accept that than to pretend you have a perfect dashboard. Use three simple methods, repeated every month:
- Question test. Write down ten questions a customer would ask, like “best dentist for implants in Campinas” or “how to choose an accountant for a MEI (Brazilian micro-entrepreneur)”. Run each one in ChatGPT, Gemini, Perplexity and Google, and record whether your company appears, in what position in the answer, and with what information. Use an incognito window and repeat the question on different days, because answers vary.
- Referral traffic in GA4. When someone clicks a source inside ChatGPT, the visit usually arrives with chatgpt.com as the source, and other tools show up with their own domain, like perplexity.ai. In GA4, open the traffic acquisition report, look at the session source / medium and filter by those domains. To measure what visitors do afterward, start with GA4 events.
- Search Console for Google. Visits from AI Overviews and AI Mode are included in the Search performance data along with everything else, with no separate breakdown. Track impressions and clicks for the pages you rewrote.
Write down your starting point before changing any page, because the number only means something in comparison.
Frequently asked questions
What is AI SEO? It’s the work of making a company’s website and profiles clear and trustworthy so that tools like ChatGPT, Gemini and Google’s AI Overviews can cite them. It’s part of SEO, not a replacement for it.
Are GEO and SEO the same thing? Not exactly. SEO aims for a position in a list of results. GEO aims for a citation inside an answer written by AI. Both share the same foundation: useful content, a well-built site and consistent information.
How do you appear in ChatGPT? Fully answer customer questions on pages of your site, use structured data, keep your Google Business Profile complete and be listed in directories and review sites with the same details. There is no guarantee of a citation, and no signup that ensures one.
Does llms.txt help you appear in AI? There’s no confirmation that the major platforms use this file. It’s cheap to create and can be added at the end of the list, after content and structured data.
Can you tell if AI is citing my company? You can estimate it. Test real questions in the tools every month, track visits with chatgpt.com and other AI domains as the source in GA4, and use Search Console for what comes from Google.
