AI OVERVIEWS CITE AI-GENERATED CONTENT MORE THAN HUMAN WRITING

Summary from the TLDR Marketing newsletter

AI Overviews on Google tend to cite AI-generated or AI-assisted content far more than purely human-written pages. A study of 1.9M URLs found that 87.8% of pages cited were a mix of human and AI content, with only 8.6% purely human and 3.6% purely AI. This contrasts with general web content, where 25.8% is purely human and 2.5% purely AI. Additionally, 86.5% of top-ranking pages contain some AI content.
