Study Finds a Third of New Websites Are AI-Generated

Researchers working with data from the Internet Archive have discovered that a third of websites created since 2022 are AI-generated. The team of researchers — which includes people from Stanford, the Imperial College London, and the Internet Archive — published their findings online in a paper titled “The Impact of AI-Generated Text on the Internet.” The research also found that all this AI-generated text is making the web more cheery and less verbose.”The proliferation of AI-generated and AI-assisted text on the internet is feared to contribute to a degradation in semantic and stylistic diversity, factual accuracy, and other negative developments,” the researchers write in the paper. “We find that by mid-2025, roughly 35% of newly published websites were classified as AI-generated or AI-assisted, up from zero before ChatGPT’s launch in late 2022.”

“I find the sheer speed of the AI takeover of the web quite staggering,” Jonas Dolezal, an AI researcher at Stanford and co-author of the paper, told 404 Media. “After decades of humans shaping it, a significant portion of the internet has become defined by AI in just three years. We’re witnessing, in my opinion, a major transformation of the digital landscape in a fraction of the time it took to build in the first place.”

Maty Bohacek, a student researcher at Stanford and one of the co-authors of the paper, added: “As AI-generated content spreads, the challenge is finding a role for these models that doesn’t just result in a sanitized, repetitive web,” he said. “Rather than forcing models to be perfectly compliant and agreeable, allowing them to have a more distinct personality or ‘friction’ might help them act as a creative partner rather than a replacement for human voice.”
