For most of its life Wikipedia lived on a simple bargain with search engines. You typed a question, Google showed a blue link, you clicked, and you landed on an article with an edit button and a history tab. The search engine got a good result. Wikipedia got a reader, and now and then a new editor or a donor. That bargain is being rewritten, and Wikipedia’s traffic decline in 2025 is the first number to show it.
What the Foundation reported
In October 2025 the Wikimedia Foundation reported that human pageviews were down roughly 8 percent compared with the same months of 2024. The figure came with a footnote worth reading. Much of an unusual traffic spike in May and June had come from bots built to avoid detection, so the Foundation rewrote its bot-detection rules and reclassified its traffic for March to August 2025. With the disguised bots taken out, the human audience turned out to be smaller than the old dashboards had suggested.
The explanation was blunt for an organisation that usually prefers the passive voice. The Foundation said it believes the decline reflects “the impact of generative AI and social media on how people seek information.” Search engines now answer questions on the results page, and younger readers look things up on video platforms instead of the open web.
The answer box keeps the reader
Pew Research measured the mechanism. It followed the browsing of 900 American adults in March 2025 and found that when a Google search showed an AI summary, users clicked an ordinary result link on 8 percent of visits. Without a summary they did so on 15 percent. The links inside the summary itself were clicked about 1 percent of the time. Wikipedia, YouTube and Reddit were among the sources Google cited most often.
Two researchers at the University of Washington tried to separate cause from coincidence. They compared English Wikipedia articles, which met Google’s AI Overviews in 2024, with the same articles in Hindi, Indonesian, Japanese and Portuguese, where the feature had not yet arrived. Their estimate is that exposure to the overviews cut daily traffic to the English articles by about 15 percent. It is one study with its own assumptions, but it points the same way as the Foundation’s counts.
The machines, meanwhile, have not stopped visiting. Pew counted more than 88 billion views of Wikipedia pages by crawlers, AI bots and other nonhuman agents in 2025 alone. Wikipedia is being read more than ever. It is simply being read by software, which then does the talking.
Why a missing click matters
On Wikipedia a click is more than traffic. It is the moment a reader can see that an article has a history, an argument behind it and people who disagree about it. In 2009 we listed a few habits for reading Wikipedia with care, starting with the most basic one: find out who wrote the article you are reading, which the page history will tell you. None of those habits survive an answer box. A summary has no history tab. It presents the current version of an article as settled fact, with the disputes and the authors left out.
The Foundation names the cost itself: with fewer visits, “fewer volunteers may grow and enrich the content, and fewer individual donors may support this work.” Wikipedia has always depended on readers who turn into editors. Someone notices an error, clicks edit and fixes it. A reader who never leaves the search page never gets the chance to notice anything.
Fewer watchers, wider reach
Early in 2010 we reported that nearly 70 percent of Wikipedia’s biographies of living people were on the watchlists of fewer than four registered editors. The problem then was a thin layer of human attention over a large and sensitive part of the encyclopedia. The answer box makes that layer thinner while widening the audience. An unwatched biography can now be quoted to millions of searchers without one of them seeing the page, the edit war or the warning templates at the top. Errors travel further and fewer people are in a position to correct them.
What attribution can and cannot fix
The Foundation says it is enforcing its policies on reuse, working on a framework for attribution so that AI products credit Wikipedia when they use it, and offering paid access to large reusers through Wikimedia Enterprise. Attribution is better than nothing. But a citation that is clicked 1 percent of the time is a footnote, not a doorway. The question is not whether the answer box mentions Wikipedia. It is whether anyone still arrives at the place where the knowledge is argued over and repaired.
The careful reader’s response
There is little an individual can do about Google’s interface. There is something to do about habits. When an answer box cites Wikipedia on anything that matters, such as a person’s reputation, a medical claim or a disputed number, open the article. Check when it was last edited, look at the history and glance at the talk page. Treat the summary as a rumour about Wikipedia, not as Wikipedia.
Wiki is Hawaiian for quick. Akahele, the word this blog is named after, means careful. The answer box is the quickest version of the encyclopedia yet, and it deserves the most care.
