Key takeaways
- Only about 12% of URLs cited by ChatGPT, Gemini, and Copilot also rank in Google's top 10 for the same prompt, per Ahrefs' 15,000-prompt analysis. Ranking and getting cited are now two different jobs.
- On WordPress sites, the most common culprit is invisible: managed hosting platforms silently throttle or block AI crawlers (GPTBot, ClaudeBot) at an infrastructure layer no WordPress dashboard shows you.
- ChatGPT cites roughly 5 sources per answer versus Google's 10 blue links, so each citation slot is more contested than a top-10 ranking.
- Publishing llms.txt or markdown mirrors of your posts has almost no effect on AI search citations. HTML pages make up 99.94% of citations in Promptwatch's data.
- Fixing this is a two-part job: clear the technical blocks (robots.txt, host-level bot rules, snippet directives), then restructure content so individual claims are citable.
The data: ranking and citing have split
Your post sits on page one of Google. You ask ChatGPT the same question and your site is nowhere in the answer. This isn't bad luck, and it isn't a bug in ChatGPT. The two systems pick sources using different signals, and the overlap between them has collapsed.
Ahrefs ran a 15,000-prompt analysis in September 2025 and found that only 12% of URLs cited by ChatGPT, Gemini, and Copilot rank in Google's top 10 for the same prompt. Semrush's study went further: when ChatGPT cites a page, that page ranks in position 21 or lower on Google almost 90% of the time. Neil Patel's team tracked 4,308 prompts and 1,161 citations and found that Google's top ten results used to account for 76% of ChatGPT citations, a number that has since fallen to 38% and keeps dropping.
The one exception is Google AI Overviews, which still pull from the organic top 10 about 38% of the time. Rank still matters most on the surface Google controls, and least on the standalone assistants.
So if you've been treating your Google rankings as proof that your content is AI-ready, that assumption stopped being safe somewhere in 2025.
Why a Google ranking doesn't transfer
Three mechanics explain most of the gap.
Retrieval, not indexing. When ChatGPT answers a question with web search on, it fetches a handful of pages and assembles an answer from passages inside them. Google's algorithm evaluates page-level relevance across hundreds of signals. AI retrieval evaluates whether a specific passage can participate in answering a specific generated sub-question. Google calls the expansion of one question into many sub-questions
