Cheap AI traffic gets harder to measure when ChatGPT drops UTM tags

Cheap AI traffic only stays honest if you can see it. On October 15, Search Engine Land reported that ChatGPT appears to drop UTM tracking, which pushes more AI visits into Direct and makes paid "AI traffic" packages even easier to fake.

What changed

Practitioner measurements around the GPT-6 window also found assistants inserting direct homepage links more often, sometimes without a useful referrer. Treat any single study as directional, but the action is the same: watch Direct and Referral together.

A low-cost measurement routine

1. In GA4, keep an AI assistants channel group on Session source for chatgpt, perplexity, gemini, copilot and claude.
2. For each major model release week, export homepage Direct sessions and compare to the prior week.
3. Add Landing page as a secondary dimension. If the lift is only the homepage, your homepage copy is now part of AI SEO.
4. Still UTM the links you publish yourself so those visits stay separable.
