AI search optimization: get ChatGPT, Perplexity, Gemini and Google to mention you
More and more people ask an AI assistant where to eat, which hotel to pick or who to call. The assistant answers with a few names and, often, a link. This page explains how that answer gets put together, what we do so your business is among the sources, and how we measure whether it happens.
What it is, in plain terms
When someone types into ChatGPT “a kid-friendly seafood restaurant in La Roma”, the assistant searches the web, reads a few pages and puts together an answer from what it found. If your site can't be read, or doesn't say clearly what you do, where and for whom, you're not part of that reading.
Working to show up in those answers is called GEO (generative engine optimization) or AEO (answer engine optimization). The term GEO comes from an academic study presented in 2024.[2] The foundation is the same old SEO: Google says no special optimizations are needed for AI Overviews or AI Mode beyond the page being indexed and eligible to show in search.[1]
How each assistant gets to your site
Each one uses its own search engine, and each search engine has to be able to get into your site:
| Where it shows up | Who reads your site | What it takes |
|---|---|---|
| Google: AI Overviews and AI Mode | Google's crawler | The page is indexed and eligible to show with a snippet[1] |
| ChatGPT search | OAI-SearchBot | Allow it in robots.txt. Sites that block it don't appear in ChatGPT search answers[3] |
| Perplexity | PerplexityBot | Allow it in robots.txt, as Perplexity recommends[4] |
| Gemini | Gemini belongs to Google. Google-Extended controls use for training Gemini and doesn't change your presence in Google Search[5] |
What we do
- Make sure they can read you. A robots.txt that lets AI search engines in, real text on the page (not just photos or PDFs) and a site that loads fast on a phone.
- Make sure they understand you. Structured data that says what your business is, where it is, what services you offer and what your frequently asked questions are. Google uses it to understand the content of a page[6] and asks that it match the visible text.[1]
- An llms.txt file. It's a summary of your site meant for AI assistants, proposed in 2024.[7] It's a proposal, not a standard, and Google doesn't require it. We add it because it costs little and organizes the information that matters most.
- Your Google Business Profile. Google ranks local results by relevance, distance and prominence, and recommends verifying your profile, keeping your information complete, responding to reviews and adding photos.[8]
- Answers with facts. Pages that answer your customers' real questions, with prices, hours and specifics. In the study that coined the term GEO, adding cited sources, direct quotes and statistics were among the changes that most increased a text's visibility, 30% to 40% in their test set, and stuffing the text with keywords didn't help.[2] It's a lab experiment, not a promise, but it points the same way as common sense: say concrete things.
How we measure whether AI cites you
An assistant's answers change depending on the question, the person and the day. A screenshot doesn't prove anything. So this is how we measure:
A fixed list of questions
The ones your customers would ask, in their words and their languages: “boutique hotel in Tulum with breakfast”, “real estate agency in Monterrey for pre-sales”.
The same questions every month
On ChatGPT, Perplexity, Gemini and Google. We note whether you show up, whether they link to you, in what position and what sources they use to talk about you.
The traffic that comes in
In Search Console, where Google counts visits from its AI features as part of normal web traffic,[1] and in Analytics, where you can see visits coming from chatgpt.com or perplexity.ai.
A short report
What changed, which pages we added and which questions still aren't bringing you in.
What no one can promise
No one controls what an AI assistant says, and Google says no one can guarantee the top spot in its search engine.[9] Be wary of anyone who promises it. What you can do is meet what Google, OpenAI and Perplexity ask for so your site can be a source, and measure honestly whether it's working.
If you'd rather do it yourself, we explain it step by step in the guide how to show up on ChatGPT and Google if you have a small business.
How much it costs
It's included with the website: from USD 300 setup and USD 39 a month, and that monthly fee includes tracking on Google, ChatGPT, Perplexity and Gemini. If you already have a site and only want this part, we quote it in writing after the Audit.
FAQ
Is it the same as SEO?
It's built on the same foundation. Google says there are no extra requirements to appear in AI Overviews and AI Mode: the page has to be indexed and eligible to show with a snippet in regular search.[1] What changes is what you write it for: besides the words people search for, the page has to clearly answer the questions people ask an assistant.
Can I let them read my site for search but not for training models?
Yes. OpenAI keeps its search crawler (OAI-SearchBot) separate from the one that collects training data (GPTBot), and each is controlled separately in your robots.txt file.[3] Google has Google-Extended for Gemini training, which doesn't change your presence in Google Search.[5] We decide it with you.
Does it work if I don't have a website?
Your Google Business Profile helps, but AI assistants build their answers from pages they can read. Without a site of your own, you depend on what other sites say about you. That's why we almost always do it together with the website.
Can you guarantee ChatGPT will recommend me?
No. No one controls those answers, just as no one can guarantee the top spot on Google.[9] Answers change depending on the question, the person and the day. That's why we track the trend month by month with the same questions.
