Wikipedia has seen a decline in users this year due to artificial intelligence summaries in search engine results and the growing popularity of social media, according to a blog post Friday from Marshall Miller of the Wikimedia Foundation, the organization that oversees the free online encyclopedia.

In the post, Miller describes an 8% drop in human pageviews over the last few months compared with the numbers Wikipedia saw in the same months in 2024.
“We believe that these declines reflect the impact of generative AI and social media on how people seek information, especially with search engines providing answers directly to searchers, often based on Wikipedia content,” Miller wrote.
Blame the bots
AI-generated summaries that pop up on search engines like Bing and Google often use bots called web crawlers to gather much of the information that users read at the top of the search results.
Websites do their best to restrict how these bots handle their data, but web crawlers have become pretty skilled at going undetected.
“Many bots that scrape websites like ours are continually getting more sophisticated and trying to appear human,” Miller wrote.
After reclassifying Wikipedia traffic data from earlier this year, Miller says the site “found that much of the unusually high traffic for the period of May and June was coming from bots built to evade detection.”
The Wikipedia blog post also noted that younger generations are turning to social-video platforms for their information rather than the open web and such sites as Wikipedia.
When people search with AI, they’re less likely to click through
There is now promising research on the impact of generative AI on the internet, especially concerning online publishers with business models that rely on users visiting their webpages.
(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
In July, Pew Research examined browsing data from 900 US adults and found that the AI-generated summaries at the top of Google’s search results affected web traffic. When the summary appeared in a search, users were less likely to click on links compared to when the search results didn’t include the summaries.
Google search is especially important, because Google.com is the world’s most visited website — it’s how most of us find what we’re looking for on the internet.
“LLMs, AI chatbots, search engines and social platforms that use Wikipedia content must encourage more visitors to Wikipedia, so that the free knowledge that so many people and platforms depend on can continue to flow sustainably,” Miller wrote. “With fewer visits to Wikipedia, fewer volunteers may grow and enrich the content, and fewer individual donors may support this work.”
Last year, CNET published an extensive report on how changes in Google’s search algorithm decimated web traffic for online publishers.
