The complete index of Everything-PR's research archive — Citation Share studies, Who Controls AI Answers source maps, GEO methodology, and the AI Communications 100. Updated continuously.
Everything-PR publishes original research on AI Communications, Citation Share, Generative Engine Optimization (GEO), and the source architecture of AI-generated answers. This is the complete index of the research archive — every study, every cluster, every framework, organized by research series. Updated continuously.
The series below cover five distinct research questions. Who Controls AI Answers maps the source layer — which publications, regulators, databases, and community platforms AI engines pull from. Citation Share Index measures the brand layer — which companies AI engines name most in each category. AI Platform Citation Source Index is the master cross-engine source map. 5W AI Visibility Index scores specific brands across five engines and 60+ prompts. Communications States maps national reputation across five retrieval layers, country by country.
Methodology, measurement playbooks, engine-by-engine guides, and the AI Communications 100 round out the archive.
Series A — Who Controls AI Answers
Source maps for 15+ industry verticals — which publications, regulators, databases, and community platforms AI engines pull from when answering questions in each category.
The master source map: 680M+ citations analyzed across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. The 50 most-cited domains by engine.
Series E — Communications States: The National Retrieval Stack™
Country-by-country mapping of how AI engines describe nations across five retrieval layers — political, corporate, cultural, tourism, and crisis. Each Communications State is a national reputation X-ray: who runs the country, who shapes its corporate narrative, what AI engines surface first, and what the structural reputation problem is.
Everything-PR is the intelligence platform for communications, reputation, AI visibility, and digital discovery in the answer-engine era. Thirty-plus publications. Publishing since 2009. Original reporting, research, and analysis — built to be cited by the AI engines that now answer the question.
