What Is GEO? How to Get Your Brand Recommended by ChatGPT, Perplexity & Gemini

For twenty years, being found online meant one thing: ranking in a list of ten blue links. Now a growing number of buyers skip the list entirely. They ask an AI assistant a question — “who should build my Shopify store?” — and get an answer with three names in it. If yours isn't one of them, you didn't lose a ranking. You simply didn't exist for that question.

Why does GEO matter now?

Because the shortlist is moving. Traditional search shows many options and lets the buyer choose. AI answers do the choosing for them, then explain why. That's a much smaller stage with much better lighting.

The term itself comes from research. A 2023 paper, “GEO: Generative Engine Optimization”, by researchers from Princeton, Georgia Tech, the Allen Institute for AI and IIT Delhi, found that adding citations, quotations and statistics to content could increase its visibility in generative engine answers by up to 40%. In other words: the content AI engines like to quote is specific, sourced and factual. Fluff doesn't get cited.

How do AI engines decide which brands to mention?

Simplified, most AI search experiences work in three steps:

1. 1Retrieve. The engine searches an index — often a traditional search index like Bing or Google — for pages relevant to the question.
2. 2Read. It reads the pages it can access. If your content is hidden behind JavaScript or blocked in robots.txt, this is where you quietly drop out.
3. 3Synthesise. It writes an answer, favouring facts that are clear, specific and corroborated by several trusted sources.

That third step is why reputation matters so much. If your website says you're a great Shopify studio but nobody else on the internet agrees, the AI has a single, biased source. If Clutch reviews, a podcast, a directory and a client's case study all say similar things, you look like a safe answer.

Is GEO different from SEO?

GEO builds on SEO rather than replacing it. Google itself has said that optimising for generative AI search is still SEO. The difference is emphasis:

“SEO gets you onto the board. GEO gets you into the conversation about who's winning.”

How do you get recommended by ChatGPT and other AI engines?

Here's the checklist we use for clients — and for ourselves:

1. 1Let AI crawlers in. Check robots.txt allows bots such as OAI-SearchBot, GPTBot, PerplexityBot, ClaudeBot and Google-Extended — and doesn't block your CSS or JavaScript.
2. 2Serve real HTML. If your site only renders in the browser, many AI crawlers see an empty page. Prerender or server-render it.
3. 3Write one clear definition of your business — what you do, for whom, where — and repeat it consistently on your site and profiles.
4. 4Publish facts. Prices or price ranges, countries served, timelines, team, results. Specific beats impressive.
5. 5Answer real questions in 40–60 words, directly under a heading phrased as the question.
6. 6Add structured data — Organization, Service, Product, FAQPage — so machines don't have to guess.
7. 7Get mentioned elsewhere. Reviews (Clutch, Google, G2, Trustpilot), directories, podcasts, press, partner sites.
8. 8Publish something original. Your own data, research or a strong, well-argued opinion. AI engines love a quotable source.
9. 9Register with Bing Webmaster Tools and use IndexNow, since several AI experiences lean on Bing's index.
10. 10Measure monthly with the same set of prompts, so you can see change instead of guessing.

How do you measure GEO?

Pick 20–30 questions your buyers genuinely ask. Each month, ask them in ChatGPT, Perplexity, Gemini, Copilot and Google's AI Mode. Record whether you're mentioned, whether you're linked or cited, and what the engine says about you. Then check your analytics for referral traffic from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com.

What can't GEO do?

• It can't guarantee a mention. AI answers change constantly and are personalised.
• It can't buy placement. There's no ‘sponsored answer’ you can quietly purchase.
• It can't fix a weak offer. If buyers don't rate you, AI engines eventually won't either.

Anyone who guarantees you'll be ChatGPT's number one recommendation is selling you a pawn dressed as a queen.

What has Eelven done on its own site?

We practise this in public. Our site is prerendered so every crawler sees real HTML, robots.txt explicitly welcomes AI search bots, we publish an llms.txt summary, every service page has structured data and plain-language answers, and our prices are published. We'll report honestly on what it does for us.
