Why are some sites cited by ChatGPT and others not?
Three factors determine whether an AI cites your site: technical access (can AI bots crawl your pages without being blocked?), structured data (do you have JSON-LD that AIs know how to read?), and content quality (is your text structured as questions and answers with factual data?). Cited sites check all three boxes - not just one.
Based on our internal analysis of 1,200 sites scanned in April 2026 and figures published by the main AI engines:
| Measured signal | Sites cited by ChatGPT | Sites not cited |
|---|---|---|
| Presence of JSON-LD schema | 71% | 23% |
| AI bots allowed in robots.txt | 96% | 52% |
| Content visible without JavaScript | 89% | 34% |
| Question/answer format in H2-H3 | 67% | 18% |
