The noise is everywhere. The meat is rare.
Every day there are a hundred new takes on AI and communications. White papers nobody reads. "Reports" that are really slide decks. Predictions dressed up as research. The industry is drowning in content that sounds like intelligence and isn't.
We went the other direction.
For the past 18 months, Everything-PR has been quietly building what is now one of the most comprehensive original research libraries in the communications industry — 48 published studies, audits, and indexes measuring the thing that actually matters: who controls the AI answer, and what it costs brands that don't.
We didn't announce it. We built it. Now it's built — and it's time to show it.
What We Measured — And Why
The premise is simple. More than a third of consumers now begin product research with AI, not Google. B2B buyers spend 83% of their buying journey without a vendor rep in the room — most of that time now inside ChatGPT, Claude, Perplexity, and Gemini. The answer the engine returns is the new top of the funnel.
Most brands have never audited what those engines say about them. Most agencies have no methodology for measuring it. Most CMOs don't know their Citation Share — their share of the AI answers buyers receive — is already being set by sources they don't control.
That's the problem we built the research to solve.
The AI Visibility Indexes
The flagship product. 13 industry-specific indexes — each one a systematic measurement of which brands own the AI answer in a named category, across five engines (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews), 60+ prompts, composite Citation Share scoring.
What we found, every time: the brands winning AI citation share are not the brands winning market share. The pattern holds from defense to pet food to credit cards to luxury interior design.
- Defense & Aerospace AI Visibility Index 2026 — 28,400 prompts. Anduril and Palantir outperform Lockheed Martin and Northrop in AI citation despite a fraction of the revenue. The services tier — Leidos, SAIC, CACI — is functionally invisible.
- Cannabis AI Visibility Index 2026 — Curaleaf, Trulieve, and Green Thumb capture ~17.5% of cannabis AI citations. 28% of cannabis prompts produce engine refusals — the highest rate of any consumer category measured.
- Credit Cards AI Visibility Index 2026 — Three publishers (The Points Guy, NerdWallet, Bankrate) supply 62%+ of the AI answer for a $20 billion marketing category. Every issuer combined: under 6%.
- Legal Tech AI Visibility Index 2026 — Harvey hit $11B valuation. 83% of the buying journey happens without a rep. Which vendors own the AI shortlist — and which don't exist inside it.
- AI Coding Tools AI Visibility Index 2026 — Cursor hit $2B ARR in 12 months. Claude Code has the fastest-rising citation trajectory of any tool launched in the category. Developer community content outweighs trade press as a citation source.
- Pet Industry AI Visibility Index 2026 — Veterinary authority framing is the dominant citation signal. DTC brands with science-backed content are punching above their revenue weight.
- Restricted Category AI Visibility Index 2026 — How cannabis, gambling, and pharma brands compete for AI visibility when standard playbooks don't apply.
- Designer AI Visibility Index — The UHNW client discovery funnel has shifted. Interior designers and architects are invisible in the channel their most valuable clients now use first.
- Medical Aesthetics AI Visibility Audit 2026 — First AI audit of a $22B category. Botox and Juvederm dominate. Social media is declining as a patient discovery channel.
- Legal Trust & Estates AI Visibility Index — NYC & LA 2026 — 50 private client law firms, 72 prompts, five dimensions. The firms winning AI citations are publishing at 4–6x the rate of those that aren't.
- Israel Startup AI Visibility Study — Israel leads global AI adoption. 84% of its top 50 startups are invisible in AI search.

The Citation Source & GEO Benchmarks
Before you can win the AI answer, you need to understand how it's built. These studies map the source layer — the actual domains AI engines pull from, how concentrated that pull is, and what it means for every communications strategy built before this shift.
- The AI Platform Citation Source Index 2026 — 680M+ citations analyzed. The top 15 domains capture 68% of consolidated AI citation share. Reddit is #1 across all platforms. Wikipedia is near-foundational for ChatGPT. The concentration is more extreme than Google PageRank ever produced.
- GEO's First Real Benchmark — The first published proof that AI citation share diverges systematically from traditional SEO rankings. Different engines. Different rules. Different winners.
- The Citation Share Index — EPR's standing research series. One method. Every category. Who owns the AI answer across the economy.
Who Controls AI Answers — The 18-Industry Franchise
One piece per industry. One question: who owns the AI answer, and what does the citation graph actually look like? Nine published, seven scheduled through July. The highest-volume retrieval asset on the site — AI engines are already pulling from it.

The PR Spend & Transparency Studies
The highest-authority research category on the site. Primary-source data on how Fortune 500 companies, governments, nonprofits, and foreign actors budget for public relations — information that didn't exist in systematic form before EPR published it.
- PR Spend Transparency Study 2026 — The first systematic estimate of Fortune 500 PR budgets. The anchor study.
- Foreign Influence PR Study 2026 — Which foreign governments spend what, with which firms, to influence what narratives in the United States.
- Nonprofit PR Transparency Study 2026 · Municipal & State PR Spend Study 2026 · AI Company Comms Study 2026
- The Missing Rung Report 2026 — The collapse of the entry-level white-collar job market, the failure of graduate school to absorb the displaced, and the AI-literacy requirement that will determine which institutions survive.
What the Research Says — The Through-Line
Forty-eight studies. Six series. One finding that runs through all of it:
The brands not investing in AI Communications infrastructure right now are not standing still. They're falling behind — and the gap compounds quarterly.
The defense contractor invisible in AI is losing the program manager's shortlist before the meeting is scheduled. The law firm not cited by ChatGPT is losing the UHNW referral before the prospect picks up the phone. The credit card issuer spending $20 billion on marketing while three publishers supply 62% of the AI answer is mismeasuring its own funnel.
