Google now often answers your search right on the page — does that actually make people click through to read more?

This explores how often Google shows an AI Overview at the top of search results. The short answer is that the collection has no study that measures how often Overviews appear, such as a share of queries or a trend over time. It does have a cluster of studies on what happens to searchers, clicks and publishers when an Overview shows up. That turns out to be the more revealing question.

The clearest measurements come from comparing searches with and without an Overview. Pew followed real browsing behavior across nearly 69,000 Google searches. People clicked a result link 8% of the time when an AI summary appeared and 15% when it didn't, and they were more likely to leave without clicking anything at all Do AI summaries on Google reduce clicks to actual websites?. Ahrefs found something similar from the keyword side: the top-ranked result's clickthrough rate is about 58% lower on queries that trigger an Overview How much are AI Overviews actually reducing organic search clicks?. Eye-tracking research shows why. The Overview now takes the spot where people's eyes land first, and the share of attention going to the first-ranked result drops from 31% to 9%. People also trust the Overview about as much as the ranked links below it Where do searchers look when AI Overviews appear?.

The effects spread past individual searches. A neat natural experiment used Wikipedia's language editions as controls: Overviews rolled out in English first, and English Wikipedia's search traffic fell about 5% compared with German and French Does AI search summaries divert traffic away from Wikipedia?. News executives expect much larger losses. They forecast that search referrals will fall 40–43% over three years Will AI Overviews reduce search referral traffic to publishers?. That figure is an expectation, not a measurement, but it shows how seriously publishers take the shift.

One finding pushes back on the 'AI replaces search' story. A study that tracked people across search engines and chat assistants found that assistant sessions usually come after searching and browsing, not before Do people use AI assistants before or after searching?. Search still tends to be where people start. The bigger change may be that the answer now sits inside the search page itself, rather than the search page disappearing. There's also a cost to learning this way: across seven experiments, people who learned a topic from an AI summary ended up with shallower knowledge than people who searched the web themselves Does learning from AI summaries produce shallower knowledge than web search?.

If you need the actual figure for how often Overviews appear, that's a gap in this collection, and you'd have to look outside it. What's here suggests that even if Overviews appeared on only a minority of searches, each appearance would cut clicks roughly in half and take the reader's first glance.
