Quick answer
Generative engine optimisation (GEO) is the practice of making your brand and content easy for AI tools such as ChatGPT, Gemini, Perplexity and Google AI Overviews to find, trust and cite. It combines strong SEO, clear factual content, consistent business information and mentions on reputable third-party sites.
Last updated: November 2026
When a potential customer asks ChatGPT “Who is the best accountant for a small limited company in Manchester?”, the answer they receive is not a list of ten blue links. It is a short, confident recommendation, and the businesses mentioned in that answer win attention that the others never get.
Generative engine optimisation, or GEO, is the emerging discipline of influencing those answers. It is new, noisy and full of exaggerated claims, so this guide separates what is known from what is guesswork.
You will learn how AI tools decide what to cite, which signals are within your control, a practical set of actions for UK businesses, and how to measure progress without fooling yourself.

How generative AI tools find and choose sources
Different tools work in different ways. Some, such as Perplexity and Google AI Overviews, retrieve live web pages and then summarise them, citing the sources they used. Others, such as ChatGPT, may combine what they learned in training with live search results when browsing is enabled.
In practice, the sources cited tend to be pages that already rank well, answer the question clearly, come from trusted sites and are easy to parse. Brands that are widely and consistently mentioned across the web are also more likely to be named in recommendations, because the models have seen them associated with the topic repeatedly.
What is the evidence, and what is hype?
Be sceptical of anyone selling a secret formula. Research and industry testing suggest a few consistent patterns: pages that rank organically are more likely to be cited, clear structured answers get extracted more often, and third-party mentions on reputable sites influence which brands are recommended.
What is not proven is that any single tactic, such as adding a special file or stuffing prompts into pages, reliably controls AI answers. Treat claims of guaranteed placement as red flags. The sensible approach is to do the fundamentals well and test carefully.
The signals you can control
- Content: direct answers, clear definitions, real examples and up-to-date facts.
- Structure: logical headings, lists, tables, FAQs and schema markup.
- Entity clarity: a consistent brand name, description, address and contact details everywhere.
- Authority: expert authors, genuine case studies, reviews and coverage on reputable sites.
- Technical: crawlable pages, fast loading and no accidental blocking of AI crawlers where you want visibility.
Why local and service businesses should care
AI assistants increasingly handle questions like “best electrician near me” or “which solicitor handles boundary disputes in Leeds”. They draw on reviews, maps data, website content and mentions. If your information is thin, inconsistent or hidden behind slow, unstructured pages, you may simply not be mentioned.
The upside is that many competitors have done nothing yet. Even modest, consistent effort can put you ahead in your local market, and the work also improves your normal search performance.
A practical GEO action plan
Start with the pages that matter most to your revenue, usually your main service pages, location pages and pricing page. For each, make the first paragraph a plain, accurate summary of what you offer, who it is for and where you operate. Add a short FAQ with the questions customers really ask.
Then strengthen your off-site footprint. Make sure your Google Business Profile, Bing Places, social profiles and key directories use the same name and description. Encourage detailed reviews that mention the service and area. Seek relevant coverage and mentions: trade bodies, local press, partner sites and industry roundups.
- Rewrite key pages with an answer-first summary.
- Add FAQ sections and relevant schema markup.
- Create comparison and “how much does it cost” pages with honest ranges.
- Publish original data, case studies or examples that others will cite.
- Keep information current and date important updates.
A GEO example for a local professional firm
Consider a small Manchester accountancy practice that wants to be recommended for “accountant for contractors”. Today its service page is a short paragraph with a contact form. To improve GEO, the firm rewrites the page with a clear opening summary: who it helps, what is included, typical fee ranges and where it works.
It adds sections on IR35, limited company set-up and VAT, each with a short plain-language answer. An FAQ covers common questions, and a case study describes a real contractor client with their permission. The firm updates its Google Business Profile with the same services and asks recent clients to mention specifics in their reviews.
It also publishes a helpful guide to contractor tax deadlines and shares it with a local business network, earning a few relevant mentions. None of these steps is exotic, but together they give an AI assistant clear, consistent and well-supported information about what the firm does and who it serves.
Within a few months, the firm is more likely to appear when people ask an assistant for contractor accountants in its area, and the same improvements also help it rank in ordinary search. That double benefit is why GEO is best treated as part of good marketing rather than a separate trick.
Should you allow AI crawlers?
Your robots.txt controls whether AI crawlers can access your site. Some businesses block them over copyright concerns; others allow them because they want to be cited. If your goal is visibility in AI answers, avoid blocking the crawlers of the tools you care about, and review your settings deliberately instead of by default.
Some people also publish an llms.txt file summarising key pages. It is a proposal rather than a standard, and there is little evidence that major systems rely on it yet, so treat it as optional housekeeping, not a ranking lever.
How to measure GEO progress
AI visibility is hard to measure precisely, because answers vary by user, location and day. Use a consistent set of 20 to 30 realistic prompts, such as “best SEO agency for plumbers in Bristol”, and test them regularly in several tools. Record whether you are mentioned, how you are described and which sources are cited.
Pair this with business metrics: branded search volume, direct visits, referrals from AI tools in analytics, and the number of enquiries that mention finding you through an assistant. Look at trends over months, not single results.
Common mistakes to avoid
- Chasing tricks instead of fixing basics such as speed, structure and accuracy.
- Publishing large volumes of generic AI-written content, which rarely earns citations.
- Inconsistent business details across the web.
- Making unverifiable claims, which AI systems and customers may distrust.
- Ignoring reviews and third-party mentions, which strongly shape recommendations.
If you want a clear view of where your business stands for both search and AI visibility, a website SEO audit is the best starting point.

Frequently asked questions
What is the difference between GEO and SEO?
SEO aims to rank pages in search results. GEO aims to get your brand cited and recommended in AI-generated answers. They share most foundations, so strong SEO supports GEO.
Can I pay to appear in ChatGPT answers?
Not directly. Organic AI recommendations are driven by content, authority and mentions, so be wary of anyone who claims they can buy placement.
Does schema markup help with GEO?
It helps machines understand your content and can improve how it is extracted, although it does not guarantee citations.
How long does GEO take to work?
Expect months, not days. Improvements in content, mentions and reviews accumulate gradually, and AI tools update their sources and models at different times.
