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.
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.
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 | 125 | 8 | 6.4% | 16% |
| Claude | 125 | 12 | 9.6% | 13% |
| Gemini | 125 | 3 | 2.4% | 20% |
| Grok | 125 | 6 | 4.8% | 18% |
| Perplexity | 125 | 3 | 2.4% | 19% |
| Copilot | 125 | 20 | 16% | 6.4% |
| 125 | 0 | 0% | 0% | |
| kagi | 125 | 9 | 7.2% | 14% |
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) | 794 | 61 | 132 |
| reddit_mention | 125 | 0 | 0 |
| Live citation (scraped answer page) | 81 | 0 | 0 |
