TL;DR: If you're a B2B healthcare or SaaS marketing leader facing CEO questions about AI visibility while competitors dominate ChatGPT recommendations, choose the partner who engineers content for LLM retrieval, not just traffic growth. Discovered Labs' CITABLE framework delivers measurable competitive gains. One client went from invisible to cited in 47% of buyer queries within 90 days, closing the gap against competitors. GrowthX focuses on AI-powered content scaling across multiple channels but lacks published methodology for Answer Engine Optimization requiring third-party validation and compliance. Month-to-month terms starting at €5,495 mean you test CITABLE for 90 days, prove ROI to your board, then decide.

Choosing the right AEO partner is not about who can write the most words. It is about who understands the retrieval logic of Large Language Models (LLMs). If you lead marketing for a B2B SaaS or healthcare tech company and your prospects ask ChatGPT or Claude for vendor recommendations, you need a methodology that drives verifiable AI citations, not just keyword rankings. This guide compares GrowthX's approach against Discovered Labs' proprietary CITABLE framework to help you decide which methodology delivers measurable competitive positioning you can present to your CEO and board.

When 48% of marketers use AI for research and LLMs cite competitors while your company is invisible, you lose deals before sales conversations start. Traditional SEO content can earn some AI citations, but content optimized for keyword density and backlinks lacks the structure and verification signals LLMs prioritize during retrieval.

The core difference between CITABLE and Growthx

The fundamental philosophical difference comes down to optimization target. GrowthX focuses on broad growth marketing, funnel optimization, and content scaling rooted in traditional SEO and user acquisition tactics. GrowthX.ai emphasizes systematic workflows producing content at scale, focusing on traffic growth and conversions across multiple channels. Their approach uses AI-driven content production to build scalable growth systems.

Discovered Labs focuses exclusively on AEO and GEO using the CITABLE framework to engineer content for LLM retrieval and citation. Where GrowthX structures knowledge work with AI-driven workflows, Discovered Labs structures content to satisfy the specific retrieval requirements of RAG systems powering ChatGPT, Claude, and Perplexity.

One optimizes for the user click. The other optimizes for the machine answer.

The distinction matters because your buyers now ask AI for vendor recommendations before visiting your website. Large Language Models use Retrieval-Augmented Generation to pull relevant information and synthesize answers. When LLMs cite competitors while skipping your brand entirely, you lose deals before sales conversations start. Traditional growth marketing tactics often lack the specific verification and entity grounding required for AI citations in healthcare and regulated B2B markets.

Deep dive into Discovered Labs' CITABLE framework

CITABLE is not a buzzword but a technical checklist for LLM optimization. We built each principle to address a specific way LLMs evaluate source quality during retrieval. Traditional SEO content prioritizes narrative flow for human readers, which can obscure verifiable facts for machines.

How the CITABLE framework works

The seven principles create a structured approach to content that LLMs trust and cite:

C - Clear entity and structure: Open with a 2-3 sentence BLUF (Bottom Line Up Front) that explicitly identifies who you are and what you do. AI models need immediate clarity about what your product or service is, who uses it, and when it applies.

I - Intent architecture: Answer the main question and adjacent questions users are likely to ask next. This creates comprehensive coverage of a topic that satisfies LLM retrieval across multiple related queries.

T - Third-party validation: Include reviews, user-generated content, community mentions, and news citations. Reddit now accounts for 40.1% of all AI model citations, far ahead of Wikipedia at 26.3%. AI models trust external sources more than your own website.

A - Answer grounding: Provide verifiable facts with sources, not vague claims. LLMs require external validation from trusted sources like journals, review sites, and industry reports before presenting information as factual. For healthcare tech companies, this means backing claims about HIPAA compliance, clinical outcomes, or security certifications with links to audit reports and case studies LLMs can verify, not just marketing copy on your website.

B - Block-structured for RAG: Use 200-400 word sections, tables, FAQs, and ordered lists AI retrieval systems can parse easily. Testing shows structured blocks increase citation probability by 30-40% compared to long-form narrative.

L - Latest and consistent: Include timestamps and ensure your facts are unified across your site, G2, Wikipedia, and other sources. Conflicting information across sources causes LLMs to skip citing brands entirely.

E - Entity graph and schema: Make explicit relationships clear, like "Our platform integrates with Salesforce and HubSpot." This helps LLMs understand relationships between concepts, leading to more accurate synthesis and citation.

Why third-party validation matters for healthcare tech

For B2B healthcare and regulated industries, the T in CITABLE (third-party validation) is non-negotiable. LLMs will not cite unsubstantiated claims about clinical outcomes, compliance capabilities, or security features without external verification from trusted sources. If your content makes claims AI systems cannot verify through G2 reviews, industry publications, or community discussions, you get skipped entirely.

Healthcare tech companies face unique compliance risk when AI systems cite and amplify content to thousands of buyers. If an LLM cites an unverified claim about HIPAA compliance or patient data security from your website, that creates regulatory exposure. The CITABLE framework mitigates this through answer grounding (verifiable facts with sources) and latest and consistent principles (unified information across all platforms). This is why traditional growth marketing content, which may prioritize narrative and conversion optimization over verification, creates risk in regulated markets.

Analyzing the Growthx content optimization approach

GrowthX operates as multiple entities with different focuses. GrowthX.ai positions itself as an AI-powered agency that structures knowledge work as living code, continuously improved through AI-driven workflows. Their stated approach emphasizes systematic, AI-driven SEO delivering consistent results with high-volume content production across multiple topic categories.

GrowthX.club takes a different approach as a growth community focusing on converting free users to paid customers, increasing ARPU, and designing low CAC distribution channels through structured frameworks and peer learning. They explicitly state they do not believe in "hacks" but in methodical, long-term sustainable outcomes.

The strength of GrowthX approaches lies in traditional funnel optimization and experimentation. However, neither entity has published a specific methodology comparable to CITABLE for Answer Engine Optimization. The focus remains on AI-powered content scaling and product growth strategies rather than engineering content for LLM retrieval requirements.

The gap becomes clear when you need specific verification and entity grounding required for AI citations in healthcare and regulated B2B markets. Traditional growth content that drives clicks often lacks the third-party validation and block structure LLMs require before citing brands. When your buyers research vendors using AI and need trustworthy recommendations backed by community validation and external sources, content must satisfy verification requirements that generalist growth marketing typically does not prioritize.

Feature comparison: Discovered Labs vs. Growthx

Feature Discovered Labs (CITABLE) GrowthX Methodology
Measurable outcomes Citation rate tracking, competitive share of voice reports, AI-referred pipeline with 2.4x conversion advantage Traffic growth, keyword rankings, funnel conversion improvements
Primary optimization goal Engineer content for LLM retrieval logic and AI citations in ChatGPT, Claude, Perplexity, Google AI Overviews Systematic AI-driven SEO approach with consistent results and content scaling
Content structure approach Block-structured (200-400 words), prioritizes third-party validation, BLUF openings High-volume production with AI-driven workflows, narrative content

The comparison reveals a fundamental difference in what each methodology optimizes for. GrowthX focuses on traditional SEO metrics like traffic growth and funnel conversions. Discovered Labs focuses on AI citation rates, share of voice in LLM responses, and pipeline from AI-referred traffic that converts at 23x higher rates according to Ahrefs data.

Why B2B healthcare and SaaS brands choose Discovered Labs

Marketing leaders in healthcare tech and enterprise SaaS choose Discovered Labs because they need measurable competitive positioning data to present to their CEO and board, not just activity reports about content published. When your executive team asks "What's our AI search strategy?" you need citation rate trends showing your company closing the gap from invisibility to meaningful share of voice versus competitors who currently dominate AI recommendations. The CITABLE framework delivers those metrics within 90 days through weekly tracking reports you can show leadership.

The need for verifiable claims in regulated industries means LLMs require external validation from trusted sources before presenting information as factual. When users present specific problems and commenters provide direct solutions with upvotes, that question-response format signals "helpfulness" that AI systems actively seek. If your brand is not discussed positively on Reddit, in G2 reviews, or across industry publications, AI systems have no community validation to reference. Your competitor who has active presence gets cited instead.

Healthcare and SaaS companies face additional constraints around compliance and accuracy. If your content makes unsubstantiated claims and AI systems cite those claims to thousands of buyers, you create regulatory exposure your legal team will escalate. The CITABLE framework addresses this through answer grounding and latest and consistent principles. This compliance-first approach is why we work with B2B healthcare tech companies who cannot afford regulatory risk from AI-cited content.

Accountability matters as much as methodology. We operate on month-to-month terms starting at €5,495 per month because we have to prove value every 30 days through measurable citation rates and pipeline impact. No 12-month lock-in. No enterprise custom quotes requiring three calls to uncover pricing. If your citation rate does not improve measurably within 90 days, you can walk away. This contrasts with traditional agency retainers requiring six to twelve-month commitments regardless of results, which creates exactly the risk your CFO and board want to avoid.

Weekly citation tracking reports show exactly where your brand appears in AI responses across ChatGPT, Claude, Perplexity, and Google AI Overviews. You see competitive benchmarking showing your share of voice versus top three to five competitors, trending upward from invisibility to measurable percentages within 90 days.

Case study: 4x growth in AI-referred trials

A B2B SaaS company approached Discovered Labs completely invisible in AI search results. When prospects asked ChatGPT or Perplexity for vendor recommendations in their category, three competitors dominated the conversation. The company was not mentioned at all, losing deals before sales conversations started.

The implementation followed the CITABLE framework across five focus areas: entity clarity through restructured product pages with BLUF openings, 45 new articles engineered for LLM retrieval with block structure, 20+ authentic Reddit mentions where target buyers discussed problems the product solves, comprehensive schema markup for entity relationships, and G2 review growth from 40 to 120 to build consensus signals AI systems trust.

AI-referred trials grew from 550 to 2,300 in four weeks, a 4x improvement in pipeline impact. More importantly, the company moved from complete invisibility to being cited by AI systems when buyers asked for recommendations. ChatGPT referrals specifically increased by 29% in the first month.

The VP of Marketing used these results to confidently present AI visibility strategy to her board. She showed before (invisible in AI search, competitors dominating recommendations) versus after (consistent citations, measurable pipeline impact) with clear data: AI-referred leads converting at significantly higher rates than traditional organic search. The board approved increased marketing budget based on demonstrated ROI and competitive advantage, positioning her as a forward-thinking leader who anticipated the AI search shift.

The conversion advantage became equally important. Prospects who arrive after AI systems recommended the brand are pre-qualified. They have already been told the product is a good fit for their specific use case.

Verdict: Which methodology drives more AI citations?

If you need broad growth marketing support across multiple channels, funnel optimization, and traditional SEO performance, GrowthX brings merit with their systematic approach to AI-powered content scaling and product growth frameworks. Their focus on building growth engines delivers value for companies seeking general demand generation improvements.

If you need to increase AI citations specifically and require verifiable, high-trust content, especially in B2B healthcare or enterprise SaaS where compliance is non-negotiable, Discovered Labs is the specialized choice. The CITABLE framework was purpose-built to satisfy LLM retrieval requirements, not adapted from traditional SEO tactics. More importantly, you get measurable citation rate data and competitive positioning reports you can present to your CEO and board showing progress within 90 days, with weekly tracking proving ROI before you commit long-term.

Your buyers ask AI for vendor recommendations before visiting your website. When competitors are cited while your brand is invisible, you lose deals before sales conversations start. For marketing leaders in regulated industries or complex B2B markets where trust and verification are non-negotiable, the methodology you choose determines whether AI systems confidently cite your brand or skip you due to lack of validation signals.

The month-to-month engagement model means you test the CITABLE framework for 90 days, measure citation rate improvements with weekly reports, and present competitive positioning gains to your board before committing long-term. That accountability model reflects confidence in the methodology's ability to deliver verifiable results you can show your CEO, not just activity reports about content published.

Frequently asked questions

How long does it take to see results with the CITABLE framework?
Initial citations typically appear within 1-2 weeks for targeted queries. Full optimization impact with measurable citation rate improvements across your priority buyer queries takes 3-4 months with consistent execution.

How does CITABLE handle healthcare regulatory and compliance requirements?
The framework's third-party validation and answer grounding principles ensure AI systems only cite verifiable, compliant content. We require external sources (clinical studies, industry reports, verified reviews) for any claims about outcomes, compliance, or security, reducing regulatory risk when LLMs amplify your content to thousands of buyers.

Is the Growthx methodology ineffective for AEO?
No, but it is not specifically optimized for LLM retrieval logic. GrowthX focuses on traditional growth marketing and content scaling which may not include the verification signals and block structure required for AI citations in healthcare and regulated B2B markets.

How do I justify the investment to my CFO or board?
Show them the opportunity cost calculation. If competitors are being cited while you're invisible, and AI-sourced traffic converts at significantly higher rates, you're losing pre-qualified pipeline every day. Month-to-month terms mean you test for 90 days and show measurable citation rate improvement before scaling investment.

How do you measure success in AEO?
We track citation rate (percentage of buyer-intent queries where your brand appears in AI responses), share of voice versus competitors, AI-referred traffic volume, and conversion rates compared to traditional organic search. Weekly reports show these metrics trending upward.

Key terminology

Answer Engine Optimization (AEO): The practice of optimizing content so AI platforms like ChatGPT, Claude, and Perplexity cite your brand when answering buyer queries. Focuses on being the answer rather than ranking on a list.

Retrieval-Augmented Generation (RAG): The architecture powering modern AI assistants where relevant content is first retrieved from sources, then the model generates a response using that retrieved content.

Share of Voice (AI context): The percentage of monitored buyer-intent queries where your brand is mentioned in AI responses versus competitors. Marketing leaders track this monthly to show boards competitive positioning improvements, closing the gap from competitors' dominance to measurable presence within 90 days.

CITABLE Framework: Discovered Labs' proprietary methodology using seven principles (Clear entity and structure, Intent architecture, Third-party validation, Answer grounding, Block-structured for RAG, Latest and consistent, Entity graph and schema) to engineer content for LLM citation.

Block-structured content: Content formatted in 200-400 word sections with tables, FAQs, and ordered lists that AI retrieval systems can parse easily during the RAG process, increasing citation probability.

Ready to see exactly where you're invisible in AI search compared to competitors? Book a strategy call with Discovered Labs and we will deliver an AI Visibility Audit showing your current citation rate versus top three to five competitors across ChatGPT, Claude, Perplexity, and Google AI Overviews. Then we build a custom roadmap using the CITABLE framework to close those gaps within 90 days. Month-to-month terms mean you test the methodology, prove ROI to your board with measurable competitive positioning gains, then decide whether to scale.
