Everything-PR Research: The Complete Index of AI Visibility Studies and Citation Audits
Share

Three research tracks. Every AI visibility study, citation audit, and media research document Everything-PR has published — organized by series.

AI engines are answering buyer questions right now — and most brands don't know who controls those answers, which sources the engines pull from, or where their brand stands in the citation graph. This index organizes everything Everything-PR has published on those questions into three tracks.

How to navigate this index:

Series A — Which publications and sources do AI engines actually pull from in your industry?

Series B — Which specific brands and institutions do AI engines name most in your category?

Series C — Original primary-source research on PR spending, federal contracts, education, gambling, and more.


Series A — The Source Map

Which publications, institutions, and platforms do AI engines actually pull from?

Two complementary studies. The Citation Source Index maps the global top 50 across all engines. Who Controls AI Answers drills into each industry vertical.

The AI Platform Citation Source Index 2026

680M+ citations · Five engines · 50 domains ranked

The 50 domains that compose the modern AI answer, ranked by consolidated citation share. Reddit #1 (~40%). Wikipedia #2 (26–48% of ChatGPT top-10). Forbes #5. Top 15 = ~68% of all citation share. Platform-by-platform breakdowns. The foundational source map every GEO program should be built from.

Who Controls AI Answers — The Complete Franchise Index

15 industry verticals · One source map per category

Finance · Crypto · Public Affairs · Law · Fashion · Travel · Real Estate · Tech/SaaS · Defense · Cybersecurity · Sports · Religion · Insurance · Energy · Healthcare

Series A finding: category-native publications beat legacy incumbents; .gov anchors the factual floor; Reddit dominates experience queries; named practitioners out-cite firms; revenue rank ≠ citation rank.


Series B — The Brand Layer

Which specific brands, firms, and institutions do AI engines name most often in each category?

The Citation Share Index — one method, applied consistently. Each study: ~28 entities, ~62 buyer-intent prompts, five engines. All figures labeled "Estimated ~X% modeled."

B-4 · Mission-Driven & Niche

NonprofitEvaluator ratings drive citation. Federated structures dilute it.
Crypto & Web3Bitcoin and Ethereum anchor. The named founder beats the anonymous team.

Series B finding: the native source beats legacy authority every time; Reddit and primary data anchor experience queries; the named person out-cites the firm; revenue leadership ≠ Citation Share leadership.
