Google Rewrote Its AI Content Guidance on 1 October

Google updated its page on using generative AI content on 1 October 2026, and the change is smaller than the commentary around it suggests. The page was brought into line with the Search Quality Raters guidelines, which Google staff have been presenting at developer events, and it now states plainly what Google expects a site owner to do before AI-assisted text goes live. What it describes is a review step. It is not a ban, and it is not a disclosure rule.

What the guidance permits and what it still penalises

Google’s guidance on generative AI content, last updated 2026-10-01 UTC, opens by saying that generative AI can help with researching a topic and adding structure to original content. It then draws the line it has always drawn: using AI to generate many pages without adding value for users may violate the spam policy on scaled content abuse. Nothing in the update moves that line, and the mechanics of the policy are in the earlier post on Google’s scaled content abuse policy.

What the update adds is a pointer to the rater guidelines. The page names section 4.6.5 of the Search Quality Raters guidelines for scaled content abuse and section 4.6.6 for main content made with “little to no effort, little to no originality, and little to no added value”. It repeats that raters’ ratings do not directly influence ranking, so the guidelines describe what Google checks its systems against, not a set of ranking factors.

The review step Google now spells out

The sentence worth acting on is the instruction to manually fact-check and review all AI-generated content for accuracy and trustworthiness before publishing. Google’s stated reason is that generative models predict likely word sequences rather than retrieve facts, so their output can contain inaccuracies, which the page calls hallucinations.

The review is not limited to body copy. The page says it also covers the metadata that can appear in Search results:

• title elements
• meta descriptions
• structured data, which should follow the general guidelines and the policy for each search feature, and be validated for eligibility
• image alt text

That list matters on a WordPress site because those four fields are the ones a bulk tool can fill for several hundred posts in one run, which is also how they escape review. A generated meta description that states a figure the article does not contain is an inaccuracy in exactly the place a searcher reads first.

Telling readers how the content was made

The page says that sharing how content was created can give readers helpful context, and that for automatically generated content a site may want to explain how automation was used and add image metadata. The wording is permissive: “can” and “consider”, not “must”. A blog post that used AI for research and a human for every sentence has no disclosure obligation under this page.

Merchant feeds are different, and the two should not be confused. The same page notes that Google Merchant Center requires AI-generated images to carry IPTC DigitalSourceType metadata set to TrainedAlgorithmicMedia, and that AI-generated product titles and descriptions must be specified separately and labelled as AI-generated. That is a feed requirement with its own documentation, in the Merchant Center policy on AI-generated content, and it applies to product data, not to articles.

What the update does not say

The page sets no percentage of AI-written text that is acceptable, and it does not claim Google detects AI text. That second point is worth keeping in mind before buying a detector to prove a draft is clean, because AI content detectors are not a reliable test of anything Google asks about. The question Google poses is whether the content is accurate, original in what it adds, and made to help people, and none of those can be read off a detector score.

For a site that publishes with AI assistance, the workable response is a documented checkpoint rather than a policy statement. Name who reviews each page, make the review cover the title, description, markup and alt text as well as the prose, and record the date. If a claim is challenged later, that record is the only evidence that a review took place.
