PressGEO Research · v0.1 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.
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 7 engines, starting May 4, 2026.
Headline numbers
By engine
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.
| Engine | Checks | Cited | Citation rate | Brand mention rate |
|---|---|---|---|---|
| ChatGPT | 148 | 0 | 0% | 0% |
| Claude | 146 | 0 | 0% | 0% |
| Gemini | 140 | 1 | 0.7% | 0% |
| Grok | 144 | 1 | 0.7% | 0% |
| Perplexity | 140 | 1 | 0.7% | 0% |
| Copilot | 140 | 1 | 0.7% | 0% |
| 142 | 0 | 0% | 0% |
By signal type
Live citations come from public answer pages we scrape. Knowledge probes come from asking the model directly.
| Signal type | Checks | Cited | Brand mentioned |
|---|---|---|---|
| Knowledge probe (asked the model directly) | 438 | 1 | 0 |
| Live citation (scraped answer page) | 420 | 3 | 0 |
| reddit_mention | 142 | 0 | 0 |
