Users who encountered an AI summary clicked on a traditional search result link in 8% of all visits. Those who did not encounter an AI summary clicked on a search result nearly twice as often (15% of visits).
A Pew Research Center report published this spring analyzed data from 900 U.S. adults who agreed to share their online browsing activity. About six-in-ten respondents (58%) conducted at least one Google search in March 2025 that produced an AI-generated summary. Additional analysis found that Google users were less likely to click on result links when visiting search pages with an AI summary compared with those without one. For searches that resulted in an AI-generated summary, users very rarely clicked on the sources cited.
There's no specific date because there's no one specific thing that the teams are working on to improve. There are multiple things, because search has multiple things that are involved in ranking.
