What Is GEO? A Plain-English Guide to Getting Found by AI

A few years ago, if someone wanted a plumber, a lawyer, or a marketing agency, they searched Google, scanned ten blue links, and picked from what showed up. That habit is changing fast. Now they ask ChatGPT. They ask Gemini. They ask Perplexity. And increasingly, they don't click through to a website at all. They just take the answer the AI gives them.

That shift has a name: GEO, short for generative engine optimization. It's the practice of positioning your business to be understood, trusted, and recommended by AI systems, the same way SEO positioned businesses to rank on Google. But the mechanics are different enough that most of what worked for traditional SEO doesn't automatically carry over.

Search and "asking" are not the same behavior

Traditional search returns a list. You, the searcher, do the comparing. Generative search returns an answer. The AI has already done the comparing, and it's handing you a conclusion: here's who to consider, here's why, here's who seems most credible.

That means the AI is making a judgment call your business either wins or loses before the person even sees a list of options. Getting left out of that judgment call is a quieter kind of invisible than not ranking on page one. You don't get a page one anymore. You just don't get mentioned.

How AI systems actually decide who to recommend

Nobody outside the AI labs knows the full recipe, but the pattern that shows up again and again comes down to a few things:

• Clear, structured information about who you are. Schema markup (structured data that describes your business, services, and offers in a format machines can parse directly) makes it much easier for an AI to understand your business without guessing.
• Consistency across the web. If your business name, description, and details say roughly the same thing on your site, your directory listings, and anywhere else you appear, that consistency reads as trustworthy. Contradictions read as noise.
• Content that actually answers the question. AI systems favor content written to directly answer a real question, not content written to rank for a keyword. Direct, specific, well-organized answers get cited. Vague marketing copy doesn't.
• Authority signals from other places. Being mentioned, linked, or cited across multiple credible sources, not just your own site, tells the AI other people vouch for you too.
• Machine-readable access. If AI crawlers (GPTBot, ClaudeBot, PerplexityBot, and others) can't reach your site or don't know what to make of it, you're simply not part of the conversation.

What this looks like in practice

Take two businesses that do the same thing. One has a homepage full of generic copy, no structured data, and no presence anywhere else online. The other has clear service descriptions, JSON-LD schema marking up exactly what it offers, a handful of published articles that actually answer common customer questions, and mentions across a few other credible sites. When someone asks an AI assistant for a recommendation in that category, the second business is simply easier to understand and easier to trust. It gets picked more often, not because it paid for placement, but because it gave the AI less work to do.

What you can actually do about it

1. Add structured data to your site. Organization and Service schema, at minimum, so AI systems and search engines have a clean, unambiguous description of who you are and what you offer.
2. Publish an llms.txt file. It's a simple, emerging standard, plain text at your site's root, that gives AI systems a direct summary of your site instead of forcing them to infer it from prose.
3. Make sure AI crawlers can actually reach you. Check your robots.txt. A missing file usually defaults to allow, but an overly cautious one can quietly lock every major AI system out without you realizing it.
4. Write content that answers real questions directly. Skip the throat-clearing. Lead with the answer, then explain it.
5. Build authority beyond your own site. One well-placed mention on a credible source does more than ten more paragraphs on your own blog.

None of this replaces good SEO. It builds on it. But treating AI visibility as an afterthought, or assuming your existing SEO work already covers it, is how businesses that are genuinely good at what they do end up invisible to the tool more and more customers are using to decide who to trust.
