The short versionGoogle updated its Search Central guidance on generative AI content on October 1, 2026. It now says it is critical to manually fact-check and review all AI-generated content for accuracy and trustworthiness before publishing, including titles, meta descriptions, structured data and image alt text. Mass-producing pages that add no value may still violate Google's scaled content abuse policy.
Google's line on AI content just got a clear new rule: a person should check it first. On October 1, Google updated its Search Central guidance on using generative AI content.
What happened
The updated page now says: "It is critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing." According to Search Engine Journal, Google's October 1 changelog says the guide was updated with information from the Search Quality Raters guidelines.
The details
Google explains why. Generative models don't look up facts; they "predict a likely sequence of words based on their training data," so their outputs may contain inaccuracies, also known as hallucinations.
The review isn't just for the article itself. Google says: "This review also applies to metadata like <title> elements, meta description elements, structured data, and alternate texts for images, which can appear in Search results."
The page also repeats an existing warning: using generative AI tools to generate many pages without adding value for users may violate Google's spam policy on scaled content abuse. Search Engine Land and Search Engine Roundtable also covered the change.
Why brands should care
Plenty of small businesses now let AI write blog posts, product pages and the bits nobody looks at, like meta descriptions and alt text. Those bits show up in Google results. A made-up statistic in a meta description is now something Google has explicitly told you to catch.
AI drafts are still fine. Publishing them unchecked is the risk.
What to do
- Add a human review step. Nothing AI-written goes live until a person has read it.
- Check every fact and number. Click through to a real source for each claim.
- Review the metadata too. Titles, meta descriptions, structured data and alt text all count.
- Don't mass-produce pages. Each page should add something a reader can't get elsewhere.
- Consider saying how it was made. Google suggests sharing how a piece of content was created where readers would expect it.
