ChatGPT mysteriously stops citing Reddit in many responses to users

Reddit, once a favorite source of information for AI chatbots, is now barely being cited by ChatGPT, according to a new report from an AI search and analytics company.

Published this week by PromptWatch, the report found that Reddit citations in ChatGPT Search fell more than 86 percent over a recent four-day period.

PromptWatch data shows that Reddit held an average share of 3.83 percent of ChatGPT citations.

This made Reddit one of ChatGPT's most cited domains from across the web.

However, within one day, that quickly changed.

PromptWatch noticed that starting on Aug.

14, Reddit's citation share plunged to less than 1 percent.

Between Aug.

14 and 17, Reddit's ChatGPT citation share fell even lower, to an average of 0.52 percent, or an 86.4 percent decline.

This is a stunning and sudden drop in ChatGPT citations for Reddit.

So, what happened? As of now, exactly why Reddit fell out of favor with ChatGPT is unclear.

The drastic decline in Reddit citations is unique to ChatGPT, according to PrompWatch's report, although there were slight decreases in Reddit citations in Google AI Overviews and AI Mode during the same timeframe.

Search Engine Journal reports that ChatGPT changed its search process on Aug.

8, but that this wouldn't explain the massive drop days later on Aug.
