Wikipedia saw an 8% drop in human pageviews between May and August 2025 compared to the same period in 2024, following updates to its bot detection systems.
The Wikimedia Foundation said the decline reflects changing habits, with more people turning to generative AI, search engines, and social media instead of visiting Wikipedia directly.
The foundation reclassified a spike in visits from Brazil as bot activity and is now enforcing stricter access policies.
Wikipedia content remains key for training large language models and powering AI tools, while new initiatives aim to engage younger audiences through platforms like YouTube and TikTok.

🧠 Food for thought
Implications, context, and why it matters.
Wikimedia Enterprise data customers remain largely unnamed despite traffic decline
- Wikimedia Enterprise enforces terms for large reusers yet it does not name which AI platforms or search engines pay, and the article gives no detail on attribution or click-through duties in Enterprise agreements.
- The paid service launched in October 2021 to serve high-volume commercial reusers via APIs with 99% Service Level Agreement (SLA) guarantees, aiming to be self-funding and reinvest revenue into the movement 1.
- Partners include ProRata.ai and Ecosia. Gist.ai uses Enterprise Snapshot plus On-demand APIs for attribution 2, and Ecosia funds tree planting 3, yet uptake by major AI players stays unclear.
- Without clarity on who pays for structured content versus who scrapes for free, it is hard to see if Wikipedia can offset the roughly 8% drop in human visits through commercial partnerships.
- Wikipedia refreshed bot classification in May 2025 after evasive traffic from Brazil masked as humans and strained infrastructure.
- Bad bots make up 37% of traffic, up from 32% in 2023, with AI tools like ChatGPT and ByteSpider lowering the bar for attackers 4.
- Publishers alongside platform operators face the same strain as 51% of web traffic is automated, so vendors that sell bot detection, API security and crawler governance can use data like simple bot attacks rising from 40% to 45% in 2024 45 to prove ROI.
- API-targeted attacks reached 44% of advanced bot traffic 5, which lets security teams tackle business logic abuse across sectors beyond Wikipedia.
