Short answer: generative engine optimisation (GEO) is the practice of making your brand, products and content easy for AI assistants such as ChatGPT, Google Gemini and AI Overviews, Perplexity and Claude to find, understand and cite. For an online store, that means letting AI crawlers access your site, writing clear answer-first content with real data, adding structured data (schema), keeping your brand facts consistent everywhere, and earning mentions on the third-party sites that AI tools trust.
Shoppers increasingly ask AI tools questions like “what’s the best running shoe for flat feet?” or “which agency can manage my Amazon account?” before they ever visit Google. If AI tools do not mention your brand, you are invisible in those moments. This guide explains how GEO and answer engine optimisation (AEO) work and gives you a practical checklist for e-commerce brands in the UK, US and UAE.
Key takeaways
- AI search is growing fast from a small base. OpenAI reported around 900 million weekly ChatGPT users in early 2026, and Adobe found AI-referred visits to US retail sites converted 31% better than other traffic during the 2025 holiday season.
- Research from Princeton and partners found that adding citations, quotations and statistics to content can raise visibility in AI-generated answers by up to 40%.
- GEO builds on good SEO rather than replacing it. Most AI tools still rely on search indexes and crawlable, well-structured pages.
- Brand mentions on review sites, forums and publications matter as much as your own website.
SEO vs AEO vs GEO: what’s the difference?
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in search results | Be the direct answer to a question | Be mentioned and cited in AI-generated answers |
| Where it shows | Google and Bing results pages | Featured snippets, voice assistants, AI Overviews | ChatGPT, Gemini, Perplexity, Claude, Copilot |
| Main tactics | Keywords, technical SEO, backlinks | Question-led content, concise answers, FAQ schema | Entity clarity, data and sources, third-party mentions, crawler access |
| Success metric | Rankings and organic clicks | Snippet and answer ownership | Share of AI answers mentioning your brand, and AI referral traffic |
How AI assistants decide which brands to mention
AI assistants answer shopping and service questions in two main ways. They draw on what they learned during training, and they search the web in real time and summarise the pages they find. To be mentioned, your brand needs to be present in both: well represented across the web over time, and easy to retrieve and quote right now.
In practice, AI tools favour sources that are crawlable, clearly structured, specific, backed by data, and confirmed by other trusted sites.
The GEO checklist for e-commerce brands
1. Let AI crawlers access your site
Check your robots.txt file. Many sites block AI crawlers such as GPTBot, Google-Extended, ClaudeBot or PerplexityBot without realising it, often through a security plugin or an old template. If you want to appear in AI answers, allow the search and answer crawlers you care about, and make sure your content is not hidden behind scripts that bots cannot read.
2. Add an llms.txt file
An llms.txt file is a simple Markdown file at the root of your site that summarises who you are, what you sell and which pages matter most. It is not an official standard, and support across AI tools varies, but it is quick to create and gives AI systems a clean summary of your brand.
3. Write answer-first content
Start every important page with a direct, one or two sentence answer to the main question, then expand. Use question-based headings that match how people ask AI tools, such as “How much does it cost to…” or “What is the best… for…”. This is the core of AEO, and it helps AI tools lift your answer cleanly.
4. Use real data, sources and quotations
The original GEO research found that adding statistics, citations and quotations were among the most effective ways to raise visibility in AI answers. Publish your own numbers where you can, such as average delivery times, return rates, results from customer projects or survey data, and link to credible sources for any figures you quote.
5. Add structured data (schema)
Schema markup helps search engines and AI systems understand your pages. For e-commerce, prioritise:
- Organization with your name, logo, founding date, contact details, locations and social profiles (sameAs).
- Product with price, availability, reviews and identifiers such as GTINs.
- FAQPage for genuine question-and-answer sections.
- Article with author and dates for blog content.
- Service for service businesses, with the areas you serve.
6. Make your brand facts consistent everywhere
AI tools build a picture of your brand from many sources. Your name, description, locations, founding year and core offer should match across your website, Google Business Profile, marketplace stores, LinkedIn, review sites and directories. Inconsistent facts make AI tools less confident about mentioning you.
7. Earn mentions on trusted third-party sites
When people ask for “the best” product or provider, AI tools lean heavily on reviews, comparison articles, forums and publications. Encourage reviews on platforms such as Trustpilot and Google, get featured in “best of” round-ups in your niche, contribute expert comments to industry publications, and take part in genuine community discussions.
8. Make product data easy to read
AI shopping features rely on clean product data. Write detailed product titles and descriptions that say who the product is for, include specifications, sizes and materials in plain text, keep prices and stock accurate, and maintain your Google Merchant Center feed. Marketplaces count too: strong Amazon, eBay and Walmart listings are often cited in AI answers.
9. Publish comparison and “best for” content
Many AI prompts are comparisons, such as “Shopify vs WooCommerce for a small clothing brand”. Honest comparison pages, buying guides and “best for” content give AI tools exactly the material they need. See our Shopify vs WooCommerce comparison for an example of the format.
10. Keep strong SEO foundations
Fast pages, clean site structure, internal links, XML sitemaps and Bing Webmaster Tools verification all still matter, because AI search tools often retrieve pages from traditional search indexes. Our e-commerce SEO checklist covers the fundamentals.
How to measure AI visibility
- Track AI referral traffic in Google Analytics 4 by filtering referrals from sources such as chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com.
- Run a prompt audit every month. Ask ChatGPT, Gemini, Perplexity and Claude the 20 to 30 questions your customers ask, and record whether your brand is mentioned, how it is described and which sources are cited.
- Watch branded search. People who hear about you from AI tools often search for your brand name afterwards.
- Ask new customers how they found you, and add “AI assistant” as an option.
Keep expectations realistic. AI referrals still make up a small share of total website traffic for most sites, often around 1%, but they are growing quickly and tend to convert well because visitors arrive with a clear intent.
GEO tips by market: UK, US and UAE
- UK: use British spelling and pricing in pounds, and build reviews on UK-trusted platforms such as Trustpilot.
- US: comparison and “best of” content is very competitive, so original data and expert quotes help you stand out.
- UAE: publish key pages in both English and Arabic, show prices in AED, and keep your marketplace listings on Amazon.ae and Noon detailed, because AI tools often cite them for local shopping questions. Our guide on selling on Amazon UAE and Noon covers the marketplace side.

Frequently asked questions
What is generative engine optimisation (GEO)?
Generative engine optimisation is the process of improving how often and how accurately AI assistants such as ChatGPT, Gemini, Perplexity and Claude mention and cite your brand, products or content in their answers.
What is the difference between GEO and AEO?
Answer engine optimisation (AEO) focuses on making your content the direct answer to specific questions, for example in featured snippets and voice search. GEO is broader: it covers how AI models understand and recommend your brand across many types of prompts, including recommendations and comparisons.
Does GEO replace SEO?
No. GEO builds on SEO. AI search tools still rely heavily on crawlable, fast, well-structured pages and on search indexes, so strong SEO foundations make GEO work much better.
How do I get my products recommended by ChatGPT?
Allow AI crawlers in robots.txt, publish detailed and accurate product information with schema, earn reviews and mentions on trusted third-party sites, create comparison and buying-guide content, and keep your brand information consistent across the web.
How long does GEO take to work?
Technical fixes such as unblocking crawlers and adding schema can affect real-time AI search results within weeks. Building brand mentions and authority across the web usually takes several months, similar to SEO.
Should I block AI crawlers to protect my content?
It depends on your goals. Blocking AI crawlers can stop your content being used, but it also reduces the chance of AI assistants mentioning or linking to your brand. Most e-commerce brands benefit more from being visible in AI answers.
