How Much of Your Website Is Written by AI?

A recent Pew Research Center study found 10% of websites show significant signs of artificial intelligence (AI) authorship. Researchers found an upward trend that began in late 2022, when ChatGPT was first released, and continued as other AI chatbots such as Claude and Gemini followed. Gradually, the share of webpages showing signs of AI authorship increased.

As researchers filtered out old webpages and only examined pages published after the release of ChatGPT, they found that one-third of pages showed signs of AI authorship.

AI-authored text is not evenly spread across the web. In samples from this year, around one-in-ten pages with a .com domain show signs of AI authorship—about double the share on .org domains (4.6%), and 10 times the rate on .edu or .gov domains (both around 1%).

While Pew said AI detection models aren’t perfect, AI test does use certain types of punctuation, and certain words and phrases show up at much higher rates in AI-generated content than in text written by humans. For example, AI models are more likely than human authors to list items in threes and to use em dashes.

Furthermore, Pew research found most Americans (76%) feel strongly that it’s important to be able to tell if pictures, videos or text were made by AI or by humans. Yet many (53%) don’t trust their own ability to spot AI-generated content.
