An AI referral is a person who clicked a link in an AI answer and landed on your site. Notra recognizes them by the referrer host: Subdomains of these hosts also count, and the server tracker and log drains go by the referrer alone. In Web analytics, a page view also counts as coming from AI when its link carries one of these hosts as utm_source, such as utm_source=chatgpt.com, which ChatGPT’s apps add because they send no referrer.

Conversions

Add Conversion paths in Brand and domains, for example /signup or /pricing, up to 20 of them. A conversion is an AI referral that lands on one of those paths. Paths match by prefix, so /pricing also counts /pricing/teams, while / only matches the home page. Conversions show up as the Conversions stage in the hero of the AI analytics page, for the selected date range.

Limits

  • Notra only counts the page the referral landed on, so a visitor who lands on a blog post and signs up later is not a conversion.
  • Notra doesn’t count visits from apps that strip the referrer header or from AI engines missing from the table as referrals.
