UTM builder for ChatGPT ads

ChatGPT already sends organic visitors to many sites, usually tagged utm_source=chatgpt.com. If your ads are not tagged differently, paid and organic ChatGPT traffic merge and you cannot judge either. Use a distinct medium for paid.

Naming that survives a year

Keep source and medium fixed across every campaign. Put the offer and market in the campaign name, and the creative variant in content. Lowercase, hyphens, no spaces. The tool enforces that for you.
