How to Apply the Framework: A 5-Step Process

Translate the 5 pillars into an actionable implementation sequence. Each step maps to one or more pillars and delivers a concrete, measurable action — moving your brand from invisible to cited.

Step
1

Audit: Your Current AI Visibility Baseline

Pillar 4

↳ Share of Model (SoM) Optimisation

Map your brand's existing footprint across LLM knowledge graphs, citation indexes, and RAG-retrieval pools. Identify which entities, topics, and definitions currently resolve to your brand — and where gaps exist.

  • Run LLM prompt tests across target queries
  • Identify entity resolution gaps in knowledge graphs
  • Benchmark SoM against category competitors
Step
2

Define: Your Entity & Definitional Content Layer

Pillars 1 & 2

↳ Entity Knowledge Graph + Structured Definitional Content

Establish schema-marked, authoritative definitions for every core concept your brand owns. LLMs cite sources that answer definitional queries cleanly — this step creates the structured content that feeds retrieval pipelines.

  • Author canonical definitions with JSON-LD schema markup
  • Resolve brand entity across Wikidata, LinkedIn, and authoritative directories
  • Publish FAQ and glossary content aligned to LLM prompt patterns
Step
3

Structure: Content for RAG Retrieval

Pillar 2

↳ Structured Definitional Content

Reorganise and format existing content so it chunks cleanly for vector embedding and retrieval-augmented generation. Structure governs whether LLMs extract, quote, and cite your content — or skip it entirely.

  • Apply heading hierarchy optimised for semantic chunking
  • Add structured tables, numbered lists, and definition blocks
  • Implement speakable and article schema across key pages
Step
4

Amplify: Sentiment Velocity & Citation Reach

Pillars 3 & 5

↳ Sentiment Velocity + Citation Reach & Source Authority

Distribute your structured content and entity signals across high-authority, LLM-indexed domains. Positive sentiment at scale across diverse sources accelerates knowledge graph resolution and improves citation probability.

  • Secure coverage on high-DA publishers indexed by major LLMs
  • Build consistent positive brand mentions across review and forum platforms
  • Pursue editorial citations from authoritative vertical publications
Step
5

Measure: Share of Model & Iterate

Pillar 4

↳ Share of Model (SoM) Optimisation

Track your brand's citation frequency across leading LLMs — ChatGPT, Gemini, Perplexity, and Claude. Use Share of Model benchmarks and sentiment analysis to quantify performance and refine prioritisation.

  • Run recurring LLM prompt monitoring across target query clusters
  • Track citation count, source authority, and sentiment score
  • Prioritise next-cycle work based on pillar-level performance data

Each cycle of the framework typically runs over 8–12 weeks. Foundgentic's audit maps your brand's current position across all five steps in under 48 hours. See how the audit works →

Methodology Context

Why AI Visibility Demands a Framework

LLMs retrieve, rank, and cite sources through RAG pipelines — not keyword indexes. Optimising for them requires a different discipline.

RAG changes the game

Large language models retrieve facts through Retrieval-Augmented Generation — pulling from semantic indexes, not keyword indexes. Appearing in those results requires entities, schema, and structured definitions, not keyword density.

Methodology over tactics

Ad-hoc optimisation fails in LLM environments because retrieval is multi-layered: entity linking, sentiment velocity, source authority, and citation reach each play independent roles. A framework unifies them into a measurable system.

GEO is a distinct discipline

Generative Engine Optimisation (GEO) targets model outputs, not SERP positions. It demands schema-marked content, knowledge graph clarity, and consistent sourcing — competencies that sit outside the traditional SEO playbook.

Traditional SEO vs LLM Optimisation

The mechanics that governed search ranking since 1998 do not transfer to generative retrieval. Here is where they diverge.

Retrieval Mechanism

Traditional SEO

Keyword index matching against crawled pages

LLM / GEO Optimisation

RAG pipeline — semantic vector search over embedded knowledge chunks

Ranking Signal

Traditional SEO

PageRank, backlinks, on-page keyword relevance

LLM / GEO Optimisation

Entity resolution, source authority, structured definitional clarity

Citation Logic

Traditional SEO

No citation — user clicks organic links

LLM / GEO Optimisation

Model cites sources that match its factual retrieval confidence threshold

Optimisation Target

Traditional SEO

SERP position 1–10; featured snippets

LLM / GEO Optimisation

LLM knowledge graph node; Share of Model (SoM) across responses

Core Methodology

The 5 Pillars of AI Search Visibility

Each pillar represents a distinct, measurable dimension of AI search visibility — structured for LLM citation eligibility and schema marking. Optimise all five to achieve authoritative brand presence across GPT, Gemini, Perplexity, and Copilot.

Entity Knowledge Graph Resolution

LLMs resolve brand mentions by matching named entities against their internal knowledge graphs. A brand that is clearly defined — with consistent entity attributes across authoritative sources — is cited more reliably and ranked higher in AI-generated answers. Resolution failure means a brand is ambiguous or invisible to the model entirely.

Key Action

Establish and harmonise entity attributes (name, category, founding date, products) across Wikipedia, Wikidata, schema.org markup, and structured press mentions.

Structured Definitional Content

RAG pipelines prioritise passages that directly answer a query with a clear, complete definition. Content structured as definition → elaboration → evidence — and marked with schema.org DefinedTerm or FAQPage — is disproportionately retrieved as a citation chunk. Vague or narrative-only content is skipped.

Key Action

Audit every core page for definitional density. Rewrite key landing pages to open with a one-sentence canonical definition, then use schema markup to expose that definition as a machine-readable snippet.

Sentiment Velocity

LLMs aggregate sentiment signals from web-scale training data and ongoing retrieval. Brands accumulate 'sentiment velocity' — the rate at which positive, neutral, or negative associations are being added to the corpus. A rapidly growing positive mention profile improves citation tone and answer framing; stagnant or declining profiles erode it.

Key Action

Monitor AI-generated answer sentiment for branded queries monthly. Run proactive content and PR programmes to increase positive-signal velocity across sources LLMs commonly retrieve from.

Share of Model (SoM) Optimisation

Share of Model (SoM) measures the proportion of relevant AI-generated answers in which a brand appears — analogous to Share of Voice but within LLM output. SoM is determined by how frequently a brand's entity and content are retrieved as the most authoritative source for a given query set, across ChatGPT, Gemini, Perplexity, and Copilot.

Key Action

Map your target query set, run systematic prompting across major LLMs, and calculate your current SoM baseline. Set quarterly SoM growth targets as a primary AI visibility KPI.

Citation Reach & Source Authority

LLMs preferentially cite sources that are themselves frequently cited by other high-authority sources — a signal of epistemic trust. Citation reach measures how broadly a brand's content, definitions, or data points are referenced by authoritative third parties: research papers, industry bodies, press, and government sources.

Key Action

Build original, citable assets — research reports, original data, industry definitions — and distribute them through channels that generate high-authority inbound citations. Structured data and persistent URLs increase citability.

Each pillar is schema-marked as a DefinedTerm within the AI Visibility methodology knowledge graph.

Framework Metrics

AI Visibility by the Numbers

The data behind why a structured AI visibility framework isn't optional. Every pillar addresses a measurable gap between where most brands sit today and where LLMs go to find answers.

83%

of LLM-cited sources use structured schema

Sources marked up with Schema.org JSON-LD or equivalent structured data are 83% more likely to appear in LLM-generated citations compared to unstructured equivalents.

68%

growth in AI-driven zero-click queries YoY

AI answer engines now resolve nearly two-thirds more queries without a click than 12 months ago — making in-model citation the new front page of search.

71%

of brand queries resolved via knowledge graph

LLMs lean on entity knowledge graphs to resolve brand identity. Without a clean, well-linked entity profile, your brand risks misrepresentation or omission.

5×

higher Share of Model for schema-optimised brands

Brands that implement all five pillars — entity resolution, structured content, sentiment velocity, SoM optimisation, and citation reach — achieve five times the AI mention rate of peers.
