Hi all, I’ve been testing how ChatGPT traffic is attributed in Piwik PRO, and I’d like to hear how others handle this. **What I found (September 2026):** - **ChatGPT on the web (desktop):** citations, source links and the business/map cards all include `utm_source=``chatgpt.com`. The first pageview is attributed correctly as AI referral. - **ChatGPT mobile app:** when the answer turns a company name into a plain text link (not a citation), the link has **no UTM and no referrer**. It opens in the in-app browser and is recorded as **Direct / Direct** , with the browser shown as “Mobile Safari” on iOS. On Android I assume it shows up as regular Chrome Mobile (Custom Tabs). - There’s no user agent or browser marker that separates ChatGPT’s in-app browser from normal Safari or Chrome. For a local service business in Norway, where the app is heavily used, I suspect a large share of AI-driven visits ends up as Direct. **Questions:** 1. Has anyone found a signal (user agent, landing page pattern, anything else) that identifies ChatGPT in-app traffic? 2. Is the issue from [this thread](https://community.piwik.pro/t/new-channel-of-ai-referral-versus-source-medium/5410) fixed by the March 2026 update, where sessions with only `utm_source=chatgpt.com` and no referrer/medium ended up as Direct? Does the AI referral channel now match on source alone? 3. How do you estimate “dark” AI traffic? For example: Direct + mobile + deep landing pages, trend analysis, or a “how did you find us” form field? ---

Hello @Treffsikker_Kjetil I was the author of the post about utm\_source=[chatgpt.com](http://chatgpt.com) showing up as direct due to the absence of a utm\_medium. As best as I can tell from my data, PP implemented my recommendation shortly after I posted. However, I am currently seeing a few sessions where the medium falls into one of the following categories: 1. Is blank 2. Contains something other than the official mediums (example: An agency using “utm\_medium=sbd” instead of “utm\_medium=display”) Back to your original question! I just accessed my website from the ChatGPT app and checked the result in PP’s tracker/debugger feature. I can see there that chatgpt provided both utm\_source and utm\_medium. ![direct-visit](https://europe1.discourse-cdn.com/flex005/uploads/piwikpro/original/2X/1/106b9e58636b98c725ad3c901e42f1a776c85c61.png) Is it possible that you’re getting hit by a lot of traffic from outside Norway? I’m U.S. based and must filter reports down to the U.S. only or my traffic is about 90% direct visits (bots). ---
