Organic clicks from Google's AI Overviews and AI Mode are not, to date, reliably and comprehensively distinguishable from classic Google SEO.
Indeed, Google transmits the same referrer google.com for a classic organic result, an AI Overview link or an AI Mode link. These visits are therefore grouped together in Google search engine traffic.
However, the situation is different for Gemini: its domain gemini.google.com can be recognized as an AI source, which allows us to categorize traffic under Gemini within the organic search channel in Eulerian.
