Every industry has an answer problem. This franchise maps who owns the answer, one category at a time.
What is Who Controls AI Answers?
Who Controls AI Answers is Everything-PR's standing research franchise mapping the retrieval anchors AI engines use to construct category answers — the specific publications, databases, regulators, and community platforms that ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews pull from when a buyer asks a question. One category per installment, each with the source map and the citation patterns.
Buyers no longer start every search with Google. In categories from finance to fashion, law to energy, the first move is increasingly a question typed into an AI engine. The answer returns a short list of sources and brands. Any brand absent from those sources may never enter consideration. This franchise identifies which sources matter, by vertical. Part of the Everything-PR Research Index.
Key Takeaways
- 15+ industry verticals mapped. Same method, same five engines, vertical-by-vertical source breakdown.
- The regulatory source anchors the factual floor. SEC.gov in finance. NIST in cybersecurity. IEA in energy. .gov is universally cited.
- Reddit owns the experience layer. Travel ("is it worth it"), real estate ("should I buy now"), law ("should I sue"), EV ownership.
- Category-native trade publications beat legacy incumbents. MJBizDaily in cannabis, Hodinkee in watches, EdSurge in EdTech.
- The named practitioner often out-cites the firm. Sotheby's auctioneers. Joele Frank. Mayo Clinic-affiliated doctors.
How to use this franchise: find your industry below, read the source map, then build or audit your earned media program against the specific retrieval anchors identified. The GEO Operating Stack is the operating model for executing against the map.

What patterns repeat across every vertical?
Five laws describe how AI engines build category answers regardless of industry. Each links to the full case-study breakdown.
- Category-native publications beat legacy incumbents. Full breakdown: GEO Case Study: How Earned Media in Category-Native Trade Press Moves AI Citation.
- The regulatory source anchors the factual layer. Full breakdown: The Regulatory Floor: Why .gov Sources Anchor Every AI Answer.
- Reddit punches above its weight on experience queries. Full breakdown: GEO Case Study: How Reddit Became the Experience Layer of Every AI Answer.
- The named person often out-cites the firm. Full breakdown: How Named Practitioners Build AI Citation Authority: The Complete Framework.
- Revenue rank and citation rank are different. Closing that gap is the core work of AI Communications.
What are the GEO Case Studies?
The franchise maps which publications to target. The GEO Case Studies explain why specific content types move AI citation — the mechanism behind each major citation vector.
- Case Study 1: How Wikipedia Became the Most Powerful AI Citation Asset
- Case Study 2: How Reddit Became the Experience Layer of Every AI Answer
- Case Study 3: How Earned Media in Category-Native Trade Press Moves AI Citation
- Case Study 4: How Schema Markup Changes What AI Engines Say About Your Brand
How do brands act on this research?
The franchise maps where engines pull from. The operating model for earning a place in those sources is the GEO Operating Stack — fourteen layers from crawler access to Citation Share. 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
What other EPR research connects to Who Controls AI Answers?
Who Controls AI Answers maps the source layer — which publications and platforms engines pull from. Three companion franchises map the rest of the AI answer system.
- The Citation Share Index — the brand layer (who gets named most in those answers by category)
- AI Platform Citation Source Index 2026 — the master source layer (50 domains across all five engines)
- The AI Communications 100 — the people layer (the 100 figures shaping the system)
All four are indexed at the Everything-PR Research Index.
Frequently Asked
What is a retrieval anchor?
A retrieval anchor is a source — publication, database, regulator, or community platform — that AI engines consistently cite when answering questions in a category. SEC.gov is the retrieval anchor for finance. NIH is the retrieval anchor for medical research. The brands that earn coverage in retrieval anchors earn AI visibility.
How is this different from the Citation Share Index?
Who Controls AI Answers maps the source layer (where engines pull from). The Citation Share Index maps the brand layer (who gets named). Two different questions, two different studies — both run on the same five-engine panel.
Which AI engines does the franchise cover?
ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews — the same five in every installment.
How do brands act on this research?
Three steps. First, identify the retrieval anchors for your category from the franchise installments. Second, audit which anchors currently mention your brand. Third, build an earned media and Wikipedia presence program targeted at the anchors where you are absent. The GEO Practitioner's Playbook sequences the work. The GEO Operating Stack is the operating model.
Why does Reddit appear in so many verticals?
AI engines treat user-generated experience discussion as more reliable than institutional marketing for many buyer-intent queries — "is it worth it," "should I buy now," "what really happens." Reddit's threaded structure, persistent URLs, and broad coverage make it the universal experience-layer source. The OpenAI–Reddit licensing deal further entrenches Reddit inside ChatGPT.
Why does .gov anchor so many factual answers?
AI engines weight authoritative, stable, citation-friendly sources for factual claims. .gov domains are non-commercial, persistent, and editorially neutral by structural design. SEC.gov, NIH, FDA, FTC, DoD, and state regulators consistently appear at Tier 1 in regulated categories. The pattern is described in The Regulatory Floor.
How often is the franchise updated?
Each installment is published with a dated source map. The index is updated as new verticals publish. The aggregate franchise refreshes quarterly to reflect material citation pattern changes.
Where can I find all the EPR studies in one place?
The Everything-PR Research Index aggregates all four research series — the source map, the brand layer, the original industry research, and the people index.
Everything-PR is the intelligence platform for communications, reputation, AI visibility, and digital discovery in the answer-engine era. Publishing since 2009. Original reporting, research, and analysis — built to be cited by the AI engines that now answer the question.
