Generative Engine Optimisation is won in the site, the content and the citations, not in the report about them.

Definition
Generative Engine Optimisation (GEO) is the 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.
01
Answer first
What a GEO tool actually is
Generative Engine Optimisation (GEO) is the 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.
A GEO tool is anything sold to move that outcome. In practice the label covers three very different things: monitors that report which brands the engines cite, content tools that draft against a gap somebody else found, and engines that do the site work, publish and earn the citation. All three are called GEO tools, which is why the label alone tells a buyer almost nothing.
02
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: no major AI crawler renders JavaScript (Vercel/MERJ, "The Rise of the AI Crawler", December 2024, analysing 500M+ GPTBot fetches).
That is the whole reason the crawl layer decides this. If an engine cannot read a page without running JavaScript, no amount of reporting on the citation you did not get will change the outcome. None of the AI-visibility specialists start at the crawl layer, where the fix actually has to land.
03
Off-site
Your site is a tenth of the answer
The second reason a report is not enough is that a brand's own site supplies only 5 to 10% of the sources an AI engine consults when it answers (McKinsey, "The new front door to the internet: Winning in the age of AI search", 16 October 2025, drawing on its AI Discovery Survey, August 2025, n=1,927). The rest is earned: citations, reviews, community and professional platforms. A GEO tool that cannot earn off-site validation is working on a tenth of the problem.

Checklist
What to judge a GEO tool on
The seven criteria of a Presence Growth Engine, in order. Tick them against whichever option you are weighing.
01
One index, five surfaces
Measures all five surfaces (Search, AI Search, Social, Reviews, Website) on a single index, with coverage shown.
02
Crawl-layer fixes
Starts at the crawl layer and writes fixes server-side into the CMS, not as an overlay or a ticket.
03
Publishes content
Publishes content, not just briefs.
04
Earns off-site validation
Earns and tracks off-site validation: citations, reviews and social.
05
Turns presence into pipeline
Turns presence into pipeline by capturing leads with names, companies and context.
06
Organic first, then paid
Runs organic first, then paid, in one system.
07
Autonomous under approval
Can run autonomously under approval, with a full action log and one-click reversal.
So the question to put to any option is not how good the dashboard is. It is what happens after the reading arrives. They show you the gap. CLEO fills the gap: it writes the fix into the CMS, server-side, publishes the content through Quill, and earns the citation, then reports the GEO Score with its confidence interval so the movement is attributable rather than asserted.
06
Evidence
The vendor record, dated
The vendor-by-vendor record is published separately and dated: what each vendor's own public material says it covers, whether it executes or recommends, how it executes and what approval model it describes, assessed on 18 September 2026 against public product documentation and public pricing, and re-checked quarterly.
Every vendor, test by test, with sources and dates. See the evidence.
Any tool sold to move Generative Engine Optimisation: structuring a brand's presence so systems such as ChatGPT, Google AI Overviews and Perplexity surface and cite it in the answer they generate. The label covers monitors, content tools and full engines, so the criteria matter more than the label.
Is GEO different from SEO?
It is the same foundation aimed at a different output. 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). A site an engine cannot read cannot be cited, whichever discipline you call it.
How should I judge a GEO tool?
Against the seven criteria of a Presence Growth Engine. Does it measure all five surfaces on one index with coverage shown, start at the crawl layer and write fixes server-side into the CMS, publish content rather than briefs, earn and track off-site validation, turn presence into pipeline, run organic first then paid, and run autonomously under approval with a full action log and one-click reversal.
Why does the crawl layer matter for GEO?
Because no major AI crawler renders JavaScript (Vercel/MERJ, "The Rise of the AI Crawler", December 2024, analysing 500M+ GPTBot fetches). A page an engine cannot read without running JavaScript cannot be ranked, cited or recommended, so the fix has to land in the source rather than in an overlay.
Where can I see how the vendors compare?
At the basis of claim, which records what each vendor's own public material says it covers, whether it executes or recommends, how it executes and what approval model it describes, assessed on 18 September 2026 and re-checked quarterly.

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.
