October 2, 2026: Google Search Central has updated its documentation on using generative AI content. The documentation update, published October 1, brings the guidance in line with material used in Google’s Search Quality Raters guidelines.

What changed

Google’s guidance continues to focus on the quality and purpose of content rather than simply whether AI was used to produce it. The updated documentation places attention on accuracy, reliability, originality and whether content is genuinely useful to people.

Google’s broader guidance also says that automated or AI-generated content should not be produced primarily to manipulate search rankings. Content creators are encouraged to review AI-assisted material carefully and ensure that the final published information is accurate and useful.

Why marketers should pay attention

For businesses using AI to produce articles, titles, descriptions, structured data or other website material, human review remains an important part of the publishing workflow. AI can speed up drafting, but factual verification and editorial judgment remain necessary before publication.

What happens next

The update reinforces a wider shift in search toward content quality, usefulness and trust. Marketers using generative AI will need workflows that combine automation with editorial review rather than treating generated text as automatically publication-ready.
