A Pew Research Center study finds roughly one third of web pages published since ChatGPT's launch show signs of AI authorship. When generic writing is nearly infinite, the only content worth publishing is the kind a model cannot fake: primary research, first-hand data and a real point of view.
The Take: The web filled up with machine-written pages faster than most marketers noticed, and that flood just reset what counts as valuable content. When generic writing is nearly infinite, the only content worth publishing is the kind a machine cannot fake.
The finding: Roughly one third of web pages published since ChatGPT's launch show signs of AI authorship, according to a new Pew Research Center analysis. Pew pulled nearly half a million English-language pages from the Common Crawl archive and found around 10% of a random July 2026 sample carried significant signs of AI writing. Sit with that. A third of everything published in three years reads like it came from the same handful of models.
Who wins: Scarcity moved. It moved away from producing words and toward producing things a model has never seen. Primary research. First-hand numbers. A named point of view that carries a real opinion and a real risk of being wrong. Australian businesses racing to publish more AI copy are pouring supply into the one part of the market where supply already crashed the price.

The tell: Google and the AI answer engines are already sorting for this. Pages that only restate what every other page says get folded into a summary and never clicked. Pages with something the model cannot generate on its own get cited. The Australian operators winning organic attention are the ones publishing what only they know, not what anything can write.
For Australian operators: Stop measuring content by volume produced and start measuring it by whether it contains something new. Put your own data, customer numbers or field observations into every piece, because that is what survives the filter. Use AI to draft and edit, not to originate the idea, since the idea is now the only scarce input. If a competitor could generate your article from a single prompt, it will not rank and it will not be cited, so do not publish it. This is the same trap covered in our take on AI and marketing value: cheaper output is not more value.
