What is the Citation Share Index?
The Citation Share Index is Everything-PR's standing research series measuring how often brands appear in AI-generated answers across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. It maps Citation Share by category: one consistent method applied across every industry, with all figures labeled "Estimated ~X% modeled." Part of the Everything-PR Research Index.
Key Takeaways
- 100+ category studies live. Same five engines, same method, modeled estimates.
- Native sources beat legacy authority in every vertical. Hodinkee out-cites Car and Driver. BetterHelp out-cites the APA.
- The named person often out-cites the firm. Joele Frank, Aravind Srinivas, Sotheby's auctioneers.
- Revenue rank ≠ Citation Share rank. The biggest brand is frequently not the most cited.
- First movers hold. LLM citation authority is archival and sticky across model updates.
Method, in brief: ~28 entities per category · ~62 buyer-intent prompts · five engines · directional source-weight modeling · "Estimated ~X% modeled" labels throughout. Full methodology inside each study.
The answer is the new shelf. The brand the engine names is the brand the buyer considers.

How is Citation Share measured?
Each study applies the same method: approximately 28 entities per category, approximately 62 buyer-intent prompts, five AI engines (ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews), and directional source-weight modeling. Figures are labeled "Estimated ~X% modeled" because AI engine logs are not public and results are modeled, not observed. Full methodology is published inside each study and in the 5W AI Visibility Index Methodology. The discipline of building Citation Share is operated commercially by 5W AI Communications, the AI Communications Firm founded in 2003 by Ronn Torossian.
What patterns repeat across every category?
Five patterns repeat across the series. They describe how AI engines build category answers regardless of vertical. Full analysis: Year-One Summary →
- The native source beats the legacy authority. Category-native publications and community surfaces out-cite decades-old incumbents in every vertical.
- Reddit and primary data anchor experience queries. On ownership-experience and due-diligence questions, community discussion and primary-source data carry the answer.
- The named person often out-cites the firm. In crisis, defense-tech, wellness, and menopause, the founder or signature practitioner carries more Citation Share than the institution behind them.
- Revenue leadership and Citation Share leadership are two different things. The biggest brand by revenue is frequently not the brand the engine names first. Closing that gap is the work.
- First movers hold their positions. LLM citation authority is archival and sticky. Brands that built authority early retain it despite competitive pressure and model updates.
What other EPR research connects to Citation Share?
The Citation Share Index measures the brand layer: who gets named. Several companion franchises map adjacent parts of the AI answer system, using related but distinct methodology. Each answers a different question.
- The AI Communications 100: the 100 people shaping what the engines say. Methodology.
- AI Platform Citation Source Index 2026: the 50 domains AI engines cite across all categories.
- Who Controls AI Answers: the specific retrieval anchors per industry vertical.
- The AI Language Citation Audit: how the same question, asked in a different language, changes which sources and brands an engine cites — four volumes running Arabic, Spanish, French, and German against English.
- The Big Tech Reputation Index and its sister NFL Owners Reputation Index: a related but separately-scored Reputation Index Family, measuring regulatory exposure, trust signals, and crisis residue rather than Citation Share.
All series are indexed at the Everything-PR Research Index.
How do brands act on Citation Share research?
The studies measure who is named. The operating model for earning a name is the GEO Operating Stack: fourteen layers from crawler access to Citation Share itself. Engine-by-engine playbooks:
- How to Rank on ChatGPT
- How to Rank on Claude
- How to Rank on Gemini
- How to Rank on Perplexity
- How to Rank on Google AI Overviews and AI Mode
