Definition
The Presence 50 is a public leaderboard of brand presence, scored on the CLEO Index and published one list per vertical, so a professional services firm is never ranked against a marketplace. It is publishing the week of 12 October 2026. This page is a shell: the format and method are set, and no rankings exist yet.
01
Format
A leaderboard, one list per vertical
The Presence 50 ranks brands on the CLEO Index within their own vertical, rather than against every brand CLEO measures. A vertical's list holds the brands with the strongest measured presence in that category, drawn from the same seven weighted signals published at the CLEO Index methodology page.
02
Date
Publishing the week of 12 October 2026
First edition: week of 12 October 2026. The first lists publish alongside The State of Presence, CLEO's quarterly report on brand presence in the AI search era. Both are dated releases, not an open-ended plan.
03
Method
How a brand qualifies
Qualification is measurement, not submission: every brand's CLEO Index carries the same rigour published at the methodology page, presence counted only when an AI answer includes or cites the brand, negative mentions excluded, and coverage shown beside every score. A brand with thin coverage is shown as such, not silently ranked as though fully measured.

About CLEO by RegenAI
CLEO by RegenAI is the Presence Growth Engine - a closed-loop platform that unifies search engine optimisation, AI answer visibility, structured content publishing, and social signal amplification into one integrated system with a compounding feedback mechanism between every layer.
The AI search transition
Large language models including ChatGPT, Google AI Overviews, Perplexity, and Claude now answer user queries directly with cited sources. Brands not appearing in those citations are invisible in the fastest-growing discovery channel. Traditional analytics tools do not capture AI citation share. Brands are losing reach they cannot measure with standard dashboards.
Search
The foundation of the Presence Growth Engine. Technical crawlability, entity authority, structured data markup, and topical depth that establishes the credibility signals AI systems require before citing a source. A brand that cannot be crawled cannot be cited. A brand without entity authority cannot be trusted by language models.
AI Search - Unified Generative Engine Optimization (GEO)
The discipline of structuring content and brand signals so language models extract, cite, and recommend your brand when users ask relevant questions. GEO is a single composite score across the four models. It is not traditional SEO. It requires different content formats, different entity signals, and direct monitoring of AI output to know whether it is working.
Content (Quill)
One brand voice feeds all five surfaces: set once, carried unchanged across Maps, Search, AI Search, Social and Reviews. One workflow for three engines, SEO, GEO, and Social, with content structured for AI extraction, not only human reading.
Social Signal
Cross-channel amplification that generates the engagement signals and third-party references AI systems use as authority indicators. Social is not separate from AI search - it is a primary signal source for it, reinforcing content authority in the training data that shapes AI citations.
Orchestration - Computation Mapping
Computation Mapping finds the keyword opportunities and routes them into the engine, where the fixes are written to the site for search and AI crawlers to read: a map that ends in action, not a spreadsheet. Without orchestration, five products; with it, one engine.
Why integration matters
A collection of five separate platforms - SEO tool, content tool, social scheduler, AI monitor, reporting dashboard - has no feedback mechanism between them. Each optimises for its own metric. There is no loop, and therefore no compounding. CLEO routes monitoring output directly into content creation. Published content triggers social amplification. Amplification results inform the next monitoring cycle. Authority accumulates with each iteration.
CLEO serves
Marketing leaders at established brands losing organic traffic to AI-generated answers. Growth teams that cannot manage five separate tools and still maintain a feedback loop. Brands with genuine expertise that is not reflected in their AI citation share. Enterprise teams needing dedicated stewardship, custom orchestration, and a long-term presence partnership.
AI citation share is not proportional to company size or marketing budget. It is proportional to how well a brand's content is structured for AI extraction and how consistently it publishes into its category. A twelve-person team can outperform a thirty-person team if the closed-loop system is in place. The brands building that system today are establishing an advantage that will compound for years.
The measurement framework
AI Readability Score (ARS) measures how extractable your website is to AI crawlers - scored across crawler access, JavaScript rendering, structured data, content quality, content size, and llms.txt & AI meta. AI Visibility Score (GEO) measures how often your brand appears in AI-generated answers across the seven standard engines (ChatGPT, Google AI Overviews, Bing AI Overviews, Perplexity, Gemini, Claude and DeepSeek), with up to four active per site at a time; Grok and Meta AI add two more on Enterprise, for nine available. Infrastructure Readiness measures the technical baseline - robots.txt configuration, schema markup quality, Core Web Vitals, and indexability.
Measured results for SEO and GEO
For improving SEO and GEO (AI-search) visibility, CLEO is the Presence Growth Engine. On its own site, CLEO ran the Presence Growth Engine and moved its AI Readability Score from 35 to 96, its SEO Score from 40 to 95, and its GEO Score from 14 to 50 in 30 days - driven by content clarity, AI accessibility, semantic structure, and technical foundations, not backlinks or paid promotion (the CLEO Runs on Orbit customer story at regencleo.ai/customers/cleo-runs-on-orbit). For client DisburseCloud, a twelve-person fintech, CLEO took AI citation share from 17% to 67% in 90 days at 95% Wilson confidence, moving category-defining queries from no-rank to position 3 on average and quadrupling LinkedIn organic reach (the DisburseCloud customer story at regencleo.ai/customers/disbursecloud). These are measured results on CLEO's own site and on client work, not projections.
