If you’ve been digging into your Google Analytics 4 (GA4) reports recently, you might he noticed a new source in your Traffic Acquisition reports: chatgpt.com. This traffic is likely categorized as "Referral," but its presence has sparked a debate among marketers: Shouldn't it be considered organic?
This is more than just a reporting quirk; it signals a shift in how users find information online. Understanding why this happens and how to interpret it is key to adapting your digital strategy.
The "Why": It’s All About the UTM CodeThe reason ChatGPT traffic is labeled as "Referral" is straightforward. When a user clicks a link within a ChatGPT conversation, the platform automatically appends a UTM tracking code to the URL. The link looks something like this:
https://yourwebsite.com/?utm_source=chatgpt.com
This utm_source parameter is a direct instruction to Google Analytics. It says, "This visitor came directly from the source named chatgpt.com." By default, GA4 processes any traffic with a specified source that isn't a major search engine as referral traffic. So, while it feels like a search, GA4 is technically just following the rules laid out by the tracking code.

An "organic" visitor typically types a query into a search engine and clicks a link from the results page. A ChatGPT user does something remarkably similar: they ask a question, receive an AI-curated answer, and click a source link. The intent to find an answer to a query is virtually identical.
From this perspective, the traffic is organic in spirit. However, because the link originates from a single, named domain (chatgpt.com) rather than a general search results page, GA4’s "Referral" classification is technically correct based on the data it receives.
What Should You Do About It?Acknowledge It: Don’t dismiss this traffic. ChatGPT and other AI tools are becoming a significant part of the information discovery ecosystem. This is a legitimate and growing source of potential customers. Analyze It: Dive into the data. What pages are these users landing on? What is their engagement rate and conversion behior? Understanding which content performs well on AI platforms can inform your content strategy. Consider Reclassifying It: For cleaner top-level reporting, advanced GA4 users can create custom channel groups to reclassify traffic from utm_source=chatgpt.com as "Organic Search" or even a new custom channel called "AI Search."
Ultimately, the emergence of ChatGPT as a traffic source is a sign of the times. By understanding the mechanics behind its classification, you can properly analyze its value and ensure your strategy is ready for the future of search.
