Pew Research — AI Overviews suppress clicks (neutral field study)
The wiki’s first non-trade, non-vendor data point — Pew Research Center, a neutral pollster, measuring real browsing behavior. This matters because of the standing vendor-incentive caveat (synthesis): most GEO/AI-search sources are SEO-trade-adjacent. Pew has no stake in declaring a new discipline, so it’s the cleanest evidence yet for the AI-Overview click-collapse.
Method
Browsing-behavior data from ~900 U.S. adults who agreed to share their activity; 58% ran at least one Google search in March 2025 that produced an AI summary. So this is observed field behavior, not a survey of opinions or an SEO vendor’s funnel sample.
The numbers
- Clicks halve with an AI summary present: only 8% of users on a results page with an AI Overview clicked a link to a website, vs 15% on a page without one — nearly 2×.
- The summary itself is a dead end for links: of results containing an AI Overview, only 1% involved clicking a link inside the summary.
- More session-ending: users ended their browsing session entirely on 26% of pages with an AI summary vs 16% without — the AI answer satisfies the query and the journey stops there.
Why it matters here
This independently corroborates two things the wiki had only on trade-press/vendor authority:
- The click-collapse thread — “AI Overviews enclose content and collapse click-through” — now has neutral numbers, strengthening the abandon-the-channel side of the optimize-vs-abandon fork.
- The ai-overviews screen-dominance + publisher-harm story (google-io-business-visibility, the Chegg/Penske lawsuits) is no longer just adversarial framing.
It does not resolve the GEO-measurability gap — Pew measures clicks lost, not whether a brand was considered by the model. So it sharpens the loss side of the ledger while the upside of “optimize for AI recommendation” stays unmeasured (google-search-console still can’t see consideration).
Caveat
Single market (US), one month (March 2025), self-selected panel; “click” behavior ≠ business outcome (a satisfied zero-click user may still convert later). Neutral source, but a snapshot.
