More Articles Are Now Created by AI Than Humans

We find that in November 2024, the quantity of AI-generated articles being published on the web surpassed the quantity of human-written articles.
We observe significant growth in AI-generated articles coinciding with the launch of ChatGPT in November 2022. After only 12 months, AI-generated articles accounted for nearly half (39%) of articles published. The raw data for this evaluation is available
here. (Google Sheet)
AI-generated Article Growth Has Plateaued
While AI-generated articles grew dramatically after ChatGPT launched, we do not see that trend continuing. Instead, the proportion of AI-generated articles has remained relatively stable over the last 12 months. We hypothesize that this is because practitioners found that AI-generated articles do not perform well in search, as shown in a separate study.
