Defined term · AEO and GEO
Be the answer the machines give.
AI answers now decide who gets recommended before a buyer ever visits a site. Measuring that is the easy part.
Definition
AI visibility is whether, and how favourably, AI systems such as ChatGPT, Google AI Overviews and Perplexity cite your brand when someone asks the question your buyers ask. Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO) are the two disciplines aimed at earning that citation. Measurement alone does not move either: a score tells you the gap exists; it does not close it.
AI visibility is one ring of the orbit. In CLEO, what the engines say is read by every other channel, and what every other channel does is measured back against what the engines say next.
Answer first
What AI visibility actually is
Both start from the same fact: an AI system can only cite what it can find, read and trust. That is a site problem before it is a content problem, which is why measurement-only tools plateau. A dashboard can show the gap in perfect detail and never close it.
Validation
Social provides AI validation
Reddit is the most-cited source across ChatGPT, Google AI Mode, Gemini, Perplexity and AI Overviews, with YouTube, LinkedIn, Wikipedia and Forbes also in the top five, and Perplexity emphasising Reddit, LinkedIn and G2 for B2B (Peec AI analysis of 30 million citation events, 31 March 2026, via Search Engine Land). AI engines lean on community, video, professional and review signals to validate and recommend a brand, so social, community and review presence is a primary input to AI search, not a side effect of it.
Market
The market context
AI search is no longer a side channel. McKinsey puts the scale at up to $750bn of US revenue that AI search could influence by 2028, drawing on its AI Discovery Survey of 1,927 respondents, August 2025 (McKinsey, "The new front door to the internet: Winning in the age of AI search", 16 October 2025). In the same survey, 45% of respondents use AI search for purchasing decisions, and 44% call it their primary and preferred source of insight, against 31% for traditional search, yet only 16% of brands track it at all. A brand's own site supplies only 5 to 10% of the sources an AI engine actually consults when it answers, which is why off-site presence, social, reviews, citations, carries the rest of the weight.
This is the market that AI visibility measures, and it is only getting bigger: AI platforms generated 1.13 billion referral visits to the top 1,000 websites in June 2025, up 357% year on year, with ChatGPT accounting for over 80% of those referrals (Similarweb, via TechCrunch, 25 July 2025).
Foundation
SEO is the foundation of GEO
Google's own guidance says SEO best practices remain relevant for AI features, with no additional requirements for AI Overviews and AI Mode (Google Search Central, AI features guidance, 2026). The industry summarises this as "AEO and GEO are still SEO". CLEO starts at the crawl layer, where AI crawlers actually read: most major AI crawlers do not render JavaScript (Vercel/MERJ, "The Rise of the AI Crawler", December 2024, from more than a billion AI crawler fetches).
Contrast
They measure. CLEO fixes.
Most AI visibility tools show where a brand is missing from the answers and leave the fixing to people. CLEO watches the answers six days a week across seven AI engines, rewrites the answers you are losing, and writes the fix server-side into your own site, where AI crawlers read it.

FAQ
Frequently asked questions
AI visibility is whether, and how favourably, AI systems such as ChatGPT, Google AI Overviews and Perplexity cite your brand when someone asks the question your buyers ask. Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO) are the two disciplines aimed at earning that citation. Measurement alone does not move either: a score tells you the gap exists; it does not close it.
Answer Engine Optimisation (AEO) is the practice of structuring a brand's content and site so an answer engine, an AI system that responds to a query with a direct answer rather than a list of links, can find, understand and cite it. Generative Engine Optimisation (GEO) is the same discipline aimed at generative search: structuring a brand's presence so systems such as ChatGPT, Google AI Overviews and Perplexity surface and cite it in the answer they generate.
No. AEO and GEO are optimisation disciplines: they require an actual site change, published content and earned citations, not a heavier dashboard. CLEO starts at the crawl layer and writes the fix into the CMS, server-side, then publishes the content and earns the citation, so the score moves because the work happened.
