How to Get Your Brand Recommended by ChatGPT: A GEO Primer
A practical breakdown of Generative Engine Optimization - the four verifiable moves that get a brand quoted by AI, and the one robots.txt mistake that's quietly killing your visibility.
You typed your own product category into ChatGPT last week, out of curiosity, and your brand didn't come up. A competitor did - one with a worse product and a worse website. That's not bad luck. That's a scoring system you haven't been playing, and most brands haven't either.
First, figure out which game you're actually playing
SEO and GEO (Generative Engine Optimization) look similar from the outside - both are about being visible when someone searches - but they're scored on completely different criteria. Google ranks pages: it cares about backlinks, keyword density, page authority, click-through behavior. An AI answer engine doesn't rank pages, it extracts sentences. It's building an answer in real time, and it needs a claim it can lift cleanly, attribute, and move on. That claim has to be structured, specific, and ideally corroborated somewhere else on the web.
SEO gets you found. GEO gets you quoted. Those are not the same skill, and most 'AI visibility' advice out there is just SEO with a new label on it.
The four things we actually did on our own site
We didn't read a whitepaper on this - we ran it on our own properties, including the clinic brand we operate, and checked what actually moved the needle by testing prompts before and after. Four changes were verifiable, meaning we could see the difference in how AI tools referenced us:
- Added an llms.txt file - a plain-text map of what our site is and which pages matter, sitting at the root domain, the same way robots.txt has worked for 20 years
- Added structured data (schema.org markup) to service pages and articles, so machines - not just humans - can parse what a page is actually claiming
- Rewrote key pages in a direct-answer format: question as a heading, answer as the very next sentence, no throat-clearing before it
- Audited and opened up robots.txt to let GPTBot, ClaudeBot, PerplexityBot, and Google-Extended actually crawl the site, instead of silently blocking them
None of these are exotic. All four are checkable in an hour with free tools. The reason most brands haven't done them isn't difficulty - it's that nobody told them these four things exist as a category separate from SEO.
What gets cited, and what doesn't
AI models pull sentences that stand alone without context - a number, a definition, a named process, a clear yes/no answer to a specific question. 'We are passionate about delivering excellence' will never get cited, because there's nothing there to extract. 'A typical CRM migration for a 10-branch clinic takes 6 to 8 weeks' might get cited, because it's a fact a model can lift and attribute without rewriting. If you want to know how to get your brand recommended by AI tools like ChatGPT, start by rewriting your best pages as if a machine, not a person, has to summarize them in one sentence.
The most common trap
We've seen this more than once: a brand's website ranks fine on Google, the SEO team is doing everything right, and yet the brand is invisible in every AI answer engine. The cause, almost every time, is a robots.txt file written years ago - before GPTBot or ClaudeBot existed - that blocks all unrecognized crawlers as a security default. Nobody revisited it. The team kept optimizing content that a bot was never allowed to read in the first place. Check this before you touch anything else - it takes two minutes and it's the single highest-leverage fix on this entire list.
GEO isn't a one-time install, it's a maintenance habit, the same way SEO became one over the last two decades. The brands that show up when someone asks ChatGPT for a recommendation next year are the ones quietly doing this work now - not the ones with the prettiest homepage.
Frequently asked questions
What exactly is GEO (Generative Engine Optimization)?
GEO is the practice of structuring your content so AI answer engines like ChatGPT, Perplexity, or Claude can extract and cite it directly, rather than optimizing purely for Google's ranking algorithm. It relies on structured data, direct-answer formatting, and machine-readable facts rather than keywords and backlinks. It sits alongside SEO, not instead of it.
How do I get my brand recommended by AI tools like ChatGPT?
Start with four checkable things: publish an llms.txt file at your root domain, add schema.org structured data to key pages, rewrite important pages in direct question-then-answer format, and confirm your robots.txt actually allows GPTBot, ClaudeBot, and PerplexityBot to crawl you. Most brands fail at the last one without knowing it - check that first.
Does GEO replace SEO, should I stop investing in SEO?
No, GEO doesn't replace SEO - they're layered, not competing. Google search still drives most transactional traffic, while AI answer engines increasingly influence early-stage discovery and trust. Dropping SEO to chase AI citations would cost you the larger channel to optimize for a smaller, faster-growing one. Do both, with different content formats for each.
Should I hire an agency for GEO, and how much does it typically cost?
It's worth outsourcing if nobody on your team can audit crawler access, structured data, and content formatting in a single pass - most in-house marketers have never touched any of the three. A proper GEO audit and implementation for a mid-size brand typically runs in the low thousands (in RM terms), not tens of thousands, since it's largely technical setup rather than ongoing spend. Before hiring anyone, ask them to show you your current robots.txt and explain, specifically, which AI crawlers it's blocking - if they can't answer that on the spot, they haven't actually done this work before.
