Google updated its Search Central documentation on October 1, 2026, adding more guidance about the use of generative AI for website content. The update incorporates information from Google's Search Quality Rater Guidelines and puts greater emphasis on reviewing AI-generated material before publication.
Human review matters more
Google's updated guidance explains that generative AI systems can produce inaccurate information because they predict likely sequences of words rather than directly retrieving facts. Google now stresses that AI-generated content should be manually checked for accuracy and trustworthiness before it is published.
The review should not be limited to the main body copy. AI-assisted workflows can also produce titles, meta descriptions, structured data, image descriptions and other page elements, making editorial review important across the entire page.
AI content is not automatically a problem
The update does not mean websites cannot use generative AI.
Google's broader guidance continues to focus on helpful, reliable, people-first content rather than simply whether AI was involved in production. The larger concern is content created primarily to manipulate search rankings, including scaled content that provides little or no additional value.
For SEO teams, the practical workflow is straightforward: use AI where it improves efficiency, but verify the output before publishing.
Check factual claims, sources, headings, title tags, meta descriptions, structured data and other important HTML elements. A technical audit can identify implementation problems, while human review determines whether the page is accurate, useful and trustworthy.
