Everything you need to know about Generative Engine Optimisation — what it is, how it works, and what to do about it.
GEO stands for Generative Engine Optimisation. Just as SEO helped businesses rank on Google, GEO helps businesses get recommended by AI systems — ChatGPT, Claude, Gemini, Perplexity, and Grok. When someone asks an AI for a business recommendation, GEO determines whether that AI names your business or your competitor's.
SEO optimises your website so Google's algorithm ranks it in a list of results. GEO optimises your entire digital presence so AI systems confidently recommend your business directly. SEO gives users ten options. GEO makes you the one answer AI gives. The signals are different too — SEO relies on backlinks, keywords, and page authority; GEO relies on structured data, consistent entity signals, FAQ content, llms.txt, AI plugin manifests, and third-party authority.
SEO is not dead, but its effectiveness is declining steadily. Google's own AI overviews push organic results further down the page, reducing click-through rates year over year. Simultaneously, a growing share of searches bypass Google entirely in favour of AI assistants. The smart move is to maintain SEO while building GEO in parallel — but the balance is shifting, and businesses that invest only in SEO are building on a shrinking foundation.
GEO affects all the major AI platforms that make business recommendations: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity, and Grok (xAI). Each uses slightly different signals and data sources, but all reward the same core qualities: authority, consistency, structured data, and genuine social proof. A strong GEO strategy improves your visibility across all of them simultaneously.
The most important GEO signals are: (1) Authority signals — genuine reviews across multiple platforms, mentions in authoritative publications, and consistent citations; (2) Structured data — JSON-LD schema markup that helps AI parse what your business does; (3) AI-specific files — llms.txt and an AI plugin manifest; (4) Consistent NAP data — your business name, address, and phone number must be identical across every platform; (5) Discovery pages — foundational pages (about, contact, FAQ, services) that give AI multiple reference points.
An llms.txt file is a plain-text file at yoursite.com/llms.txt that introduces your business directly to AI systems. Think of it as a business card written for AI — it tells AI who you are, what you do, who you serve, and what makes you credible. It is one of the highest-impact GEO improvements you can make. Without it, AI is guessing about your business from scattered data. With it, AI has a direct, authoritative source to draw on.
JSON-LD (JavaScript Object Notation for Linked Data) is a format for adding structured data to your website that machines can easily read. For GEO, it allows you to tell AI systems exactly what your business is, what it offers, where it operates, who it serves, and what questions it can answer. Without schema markup, AI has to guess at this information from your HTML. With it, AI has a clean, unambiguous data feed directly describing your business.
GEO timelines vary by signal type. Technical improvements — JSON-LD schema, llms.txt, AI plugin manifest — can be implemented immediately and may be picked up by AI systems within weeks. Authority signals — reviews, citations, publications — build over 3 to 6 months of consistent effort. For most businesses, meaningful improvements in AI recommendation frequency are visible within 3 to 6 months of a comprehensive GEO programme.
The simplest way is to ask. Go to ChatGPT, Claude, Gemini, and Perplexity, and ask each one to recommend a business in your category and location. See if your business appears. You can also run a free AI Visibility Audit at AgentConsoleHQ — it scores your site across 10 key signals and shows you exactly where your gaps are, in 30 seconds, with no sign-up required.
GEO can actually advantage small businesses, especially in local and niche markets. A well-executed GEO strategy for a local business can make it the default AI recommendation in its area — competing directly with much larger businesses that haven't optimised for AI discovery. Many GEO improvements are free. Small businesses that act early can establish AI recommendation authority before better-funded competitors wake up to the opportunity.
GEO makes your business visible when AI is asked for recommendations — it's optimisation for passive discovery. Agentic selling goes further: it deploys AI agents that actively promote and sell your business across AI platforms 24 hours a day. GEO gets you found. Agentic selling actively converts. The two strategies work together — GEO builds the foundation of AI trust, while agentic selling leverages that visibility to drive active customer acquisition. AgentConsoleHQ provides both.
Start with an AI Visibility Audit. Run your site through AgentConsoleHQ's free audit tool — it checks 10 signals in seconds and shows you your score. From there, prioritise: (1) Add llms.txt if you don't have one, (2) Add JSON-LD schema to your key pages, (3) Ensure your Google Business Profile is complete and active, (4) Build genuine reviews across multiple platforms. These four steps address the highest-value GEO signals and are achievable for any business.
