ChatGPT does not cite Reddit
Google AI Overviews cites Reddit in 18.8% of its answers with sources, while ChatGPT never does in this window. The same platform can matter a great deal for one LLM and not at all for another, so the right mix depends on which ones your buyers use.

How we collect this data
Every AI visibility audit we run writes buying questions for a company’s market and puts each one to every LLM through its API, with web search on. We record the answer and the pages it cites, and these reports add them up, one audit per company.
Written by the audit for each company's own market.
Every answer and every source it cites, from the last 90 days.
Each report keeps its earlier editions, so you can see what moved.
Added up across companies. No single company's results are shown.
Method notes
- Window
- July 17, 2026 to October 15, 2026, rebuilt October 15, 2026.
- Sample
- 517 companies across 199 categories, one audit per company, its latest in the window. Each audit writes buying questions for that company's market with an LLM and puts each one to every LLM through its API.
- Models
- ChatGPT means GPT-4o mini with web search, through the OpenAI API. Claude means Claude Haiku 4.5 with web search, through the Anthropic API. Gemini means Gemini 2.5 Flash with Google Search grounding, through the Gemini API. Perplexity means Perplexity Sonar, through the Perplexity API. Google AI Overviews means the AI Overview on a live Google results page, read through DataForSEO.
- How it is counted
- A platform counts once per answer. Subdomains count with their platform, so old.reddit.com counts as Reddit and twitter.com counts as X. Links to Google Maps, Google search and product viewers, and image servers are dropped first, because none of them is a page a reader can check.
- Citation figures
- Cover ChatGPT and Google AI Overviews, counting only the pages each answer cites. Claude, Gemini and Perplexity join once 300 of their answers are recorded with cited pages alone, which started on October 15, 2026. Until then their answers count toward the totals only.
