ChatGPT traffic just vanished from your analytics

Glenn Gabe says ChatGPT has now stripped tracking tags from every link it cites, so your analytics will show a big drop in ChatGPT visits that never actually happened. He thinks it is a bug.

Why your traffic moved

Study shows Wikipedia and news sites win AI citations

A study of 222,753 Google searches across 76,450 public conversations looked at how Gemini, Google's AI assistant, picks the sources it credits. Wikipedia and news sites lead the citations, YouTube gets read but is rarely cited, and Gemini can also search without showing any sources at all.

Who this affects: Anyone wondering why AI answers rarely link to their site.
