PressGEO Research · v1.0 baseline

The state of AI citations in press distribution.

A continuously-updated benchmark of which AI engines cite press releases — and at what rate. Every number on this page is computed live from the PressGEO Citation Monitor.

By PressGEO Research·Updated Sep 2, 2026

Methodology

We continuously probe seven AI surfaces — ChatGPT, Claude, Gemini, Grok, Perplexity, Copilot, and Reddit — with high-intent queries tied to releases in the PressGEO network. Two signal types are recorded: live citations (the model's public answer page lists the release URL) and knowledge probes (the model is asked the citation-likely query and we check whether it surfaces the company). A row is cited only when a target URL is present. A row is brand-mentioned when the company name appears in the answer with no URL. The window below covers 1,000 checks across 8 engines, starting Aug 3, 2026.

Citation rate is the share of checks where the model returned the target URL. Brand-mention rate is the share where the company name appears without a URL citation.
