Share of tagged visits that also carry a ChatGPT referrer

Share of ChatGPT referrer visits from the Android app

Average visits per day, by week (Thursday to Wednesday), Oct 23, 2025 to Oct 20, 2026, indexed: 100 is the average day of tagged visits in the first week. The last week is 6 days. The grey week, Oct 8–14, is a GPT-6 rollout bug that stripped both the tag and the referrer; the lines bridge it. Dashed lines, from public reporting: May 7, links to brands in ChatGPT answers; Aug 6, GPT-5.6 for Free & Go; Oct 8, GPT-6 for Free & Go. The ChatGPT referrer is chatgpt.com, chat.openai.com or the Android app. The Android app referrer first appears on October 11–13, 2026. It makes up 35% of ChatGPT referrer visits in the last week and over 40% by October 20. Source: AEM Operational Telemetry, sites it measures, bots excluded.
