How do I track which AI assistant sent a visitor to my website?
We think ChatGPT and Perplexity are sending us visitors, but our reports don't show it clearly. How do we see which assistant a visit came from?
Answer from the Linkrunner team
Check three signals, in this order. First, the referrer domain: look for chatgpt.com, perplexity.ai, claude.ai, gemini.google.com, copilot.microsoft.com and grok.com in your referrer report. Second, UTM tags: some ChatGPT links carry utm_source=chatgpt.com, though not every link does. Third, landing pages: AI visits often land on deep pages such as comparisons and how-tos. Then report them as a channel of their own with an ordered rule: match the referrer first, the UTM source second, and leave everything else in its usual bucket. Referrer and tagging behaviour varies by assistant, app and browser, and changes without notice, so treat any list as a snapshot and check your own data. Linkrunner's Web SDK (beta) classes visits from ChatGPT, Perplexity, Claude, Gemini, Copilot and Grok as AI traffic automatically.
