~35% of New Websites Since ChatGPT Launch Are AI-Generated or AI-Assisted
Internet Archive data through mid-2025 shows that approximately 35% of new websites created since ChatGPT's late-2022 debut are AI-generated or AI-assisted — roughly one in three new sites on the web. The finding is based on analysis of the Archive's crawl data across the period, providing the most rigorous longitudinal measurement to date of AI's structural impact on web content production. The figure does not distinguish between fully autonomous generation and AI-assisted human workflows, but the combined share is significant regardless.
Why It Matters
A third of new web infrastructure being AI-generated in under three years marks a structural shift that content discovery systems, trust and safety frameworks, and LLM training pipelines were not designed for. This finding directly reinforces the AEO/GEO citation research: if a growing share of the web is algorithmically generated, the narrow human-curated platforms (Reddit, Wikipedia, G2) that LLMs preferentially cite become even more important as trust anchors.
