Reddit citations in ChatGPT drop 86% after search source changes
gaganghotra_ · x · 2026-08-18
Data reveals a cliff-like drop in Reddit citations within ChatGPT Search on August 14, falling from a steady 3.8% share to 0.5%, an 86% relative decline. The slide began after ChatGPT modified its query fanout behavior on August 8. While Google AI Overviews shows a gradual decline for Reddit, it lacks the sudden collapse seen in ChatGPT. The report suggests a shift in source selection strategy as the likely cause, though data collection issues have not been ruled out.
