Links in ChatGPT stopped carrying the utm_source=chatgpt.com parameter. Adobe's data on about 500 pages showed ChatGPT visits down roughly 31,000 per day, with direct traffic up roughly 26,000 per day.
OpenAI has now confirmed it was a bug. A fix started rolling out on October 15 and ChatGPT traffic is back to about normal.
My tip: if your October reports show a ChatGPT dip with a direct spike, annotate it as a tracking issue.
