Google updates its generative AI content guidance and tells publishers to manually fact-check titles, meta descriptions and alt text before publishing

A team that drafts page copy with a model has a new rule from Google to follow before it hits publish, and the rule names every field on the page. Google Search Central updated its "Using generative AI content" guide on 1 October 2026 to say it is critical to manually fact-check and review all AI-generated content for accuracy and trustworthiness before publishing, and listed four places where that review has to happen beyond the body.

The new paragraph in the guide names the title tag, the meta description, structured data and image alt text as metadata that can appear in Search results and that falls under the same manual review. Google's reason, in the same paragraph: generative models do not retrieve facts, they predict a likely sequence of words, so AI output may contain inaccuracies. The guide calls hallucinations by name.

Where the text came from

Google says, in the 1 October entry on its Search Updates page, that the new wording was pulled from the Search Quality Raters guidelines to sync the public documentation with the presentations Google uses at its developer events. The raters are the human panel Google pays to score sample Search results against those guidelines. Their scores are not direct ranking signals, Google writes, but the guidelines carry what Google thinks a quality page looks like.

Nothing in the update changes Google's existing spam policy on scaled content abuse. The guide still says that using generative AI to produce many pages without adding value for users may violate that policy. Matt G. Southern of Search Engine Journal, who covered the update on 1 October, points at the same two sections of the Raters guidelines that Google references: 4.6.5 on scaled content abuse, and 4.6.6 on main content made with little effort, originality or added value.

What a team should change this week

The review step is the one new line of work. A page that goes through an AI drafting pipeline has a title tag, a meta description, structured data and alt text that each have to pass through a person's hands before publishing, in addition to the body of the page. For a team already running an editor on bodies, the gap is often the four metadata fields that pages pick up from a template or from a model that drafted them alongside the body.

A team that cares about structured data has one more line to follow. The guide repeats the general requirement that structured data must comply with Google's structured data policies and be validated against the markup rules for each search feature. An AI-written JSON-LD block that is not read by a person can still contain the right JSON and the wrong facts, and a reviewer who only checks the body misses that half of the page.

Google has not said anything in this update about ranking changes tied to the new text. The guide ties the manual review to the existing spam policy on scaled content abuse, so a page already compliant with that policy, and already reviewed by a person before publishing, needs no new work.
