AI Referral Traffic

Create a dedicated channel group by referrer domain so the major AI platforms are recognised instead of landing in Direct / Other.

Some platforms pass no referrer at all. That portion can only be estimated from landing-page patterns and timing correlation — and estimates must be labelled as estimates.

Do not forget the indirect path: people who see the brand in an AI answer and then search the brand name or type the URL carry no AI referrer, but they are still a product of AI visibility.

Cross-site studies put the average at roughly one percent of traffic. In absolute terms this remains orders of magnitude below conventional search.

Growth is a different story, with referral volume multiplying within a single year. The value of this metric is in trend and structure, not in this quarter's volume.

Several studies point the same direction but disagree wildly on magnitude, from a few times to more than ten, using very different methods.

There is also counter-evidence: at least one statistical analysis found no significant overall difference. The defensible phrasing is that it is worth watching separately — not that it converts some specific multiple better.
