Google AI Generated Content Guidelines: What to Fact-Check

Google's AI generated content guidelines allow AI-assisted pages, but say it is "critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing," and warn that mass-producing pages without added value may violate Google's spam policy. The guide, last updated October 1, 2026, names titles, meta descriptions, structured data and image alt text as part of that check.

Key points

• Google's October 1, 2026 update adds language from its Search Quality Raters guidelines to its guide on AI-written content.
• The fact-check rule reaches the parts of a page that can show up in Search results, not just the body copy.
• Google says there is no separate rulebook for AI Overviews and AI Mode, so this guidance applies to pages that want to appear there too.

What changed in Google's AI generated content guidelines?

Google's Search documentation changelog for October 1, 2026 reads: "Updated the using generative AI content guide with information from the Search Quality Raters guidelines." Search Engine Journal and Search Engine Roundtable both reported on the revision.

The guide says generative AI "can be particularly useful when researching a topic, and to add structure to original content." It also tells site owners that "it is critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing," and explains why: "generative models don't retrieve facts, but predict a likely sequence of words based on their training data." Google adds that "generative AI outputs may contain inaccuracies (also known as hallucinations)."

A draft from ChatGPT, Gemini or Claude can read smoothly and still contain a wrong date, a wrong price or a service you don't offer.

Does this affect Google AI Overviews and AI Mode?

Yes. Google doesn't run a separate content standard for its AI features. Its AI features documentation says "the best practices for SEO remain relevant for AI features in Google Search (such as AI Overviews and AI Mode)" and that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."

To be eligible as a supporting link, Google says a page "must be indexed and eligible to be shown in Google Search with a snippet." So the same quality guidance that governs regular results governs the pages AI Overviews and AI Mode can pull from. If you've read our guide to answer engine optimization for Google AI Overviews, this update is the content-quality half of that picture.

What does "review all AI-generated content" actually cover?

Google's guide says the fact-check applies to "`<title>` elements, meta description elements, structured data, and alternate texts for images, which can appear in Search results."

Because those fields can shape how your page appears in Search, a wrong line there can reach a searcher before they click. If you're short on time, check those fields before you reread the body copy, starting with the title and meta description, since they're the text a searcher may read in a result. Then check structured data, because it states your hours, address and services as facts.

Two other lines are worth knowing:

• Disclosure is suggested, not required for most sites. Google says to "consider adding information on how your content was created in a way that makes sense for your audience."
• Merchant Center submissions have firmer rules. If you send product listings to Google Merchant Center, its policy says "all images created using generative AI must contain meta data indicating that the image was AI-generated," and AI-written product titles and descriptions go in separate attributes. These rules cover Merchant Center product data, not a regular service page.

What should you check before publishing an AI draft?

1. Trace every fact. Each number, date, name and claim should match a source you opened, not the tool's memory.
2. Read the title and meta description. These usually sit in a separate SEO or page settings panel in your website editor, not in the page text, so open that panel. Confirm they describe what's actually on the page.
3. Compare structured data to the page. Hours, address, services and prices in your markup should match the visible text. If you didn't add the markup yourself or can't find it, ask whoever built or maintains your site to pull it up.
4. Read the image alt text. Make sure it describes the real image.
5. Ask what's original. Add something only your business knows, like how you actually do the work.
6. Decide on disclosure. If your readers would want to know how the page was made, say so.

Hypothetical example: a plumbing company's AI draft says it offers drain cleaning and weekend emergency calls. Drain cleaning is on its current service list, so that line passes. It doesn't take weekend calls, and the auto-filled meta description repeats that line, so both fail and get cut or corrected before the page goes live.

What does Google mean by high-quality main content?

Google's guide to creating helpful content says that "beyond E-E-A-T, the Search Quality Evaluator Guidelines emphasize that one of the most critical factors for assessing page quality is the quality of the main content." It lists four attributes:

For topics that could affect someone's health, money or safety, Google says content "must be highly accurate and consistent with established expert consensus."

Does Google penalize AI content now?

Google's guide doesn't ban AI-written content. The risk it names is volume without value: using AI "to generate many pages without adding value for users may violate Google's spam policy on scaled content abuse." Before you publish an AI-assisted page, ask three things: is every fact confirmed, does it say something other sites don't, and would a customer learn something useful from it? If any answer is no, fix the page or hold it.

What should an owner do this week?

Pull up the five pages a new customer is most likely to see: your home page, your top three service pages and your contact or location page. Run the checklist above on each, starting with the title, meta description and structured data, and fix anything an AI tool wrote that you can't confirm. Google AI Overviews and AI Mode can only link to pages that are indexed and eligible for a snippet, so those pages are what they have to work with.

FAQ

Does Google penalize AI-generated content?

Not for being AI-generated. Google's guide warns that using AI to produce many pages without adding value for users may violate its spam policy on scaled content abuse.

Do I have to label AI-written content?

For most sites, Google says to "consider" explaining how content was made. If you submit products to Google Merchant Center, its policy requires metadata on AI-generated product images and separate attributes for AI-written product titles and descriptions.

Does the fact-check rule apply to meta descriptions and alt text?

Yes. Google's guide names title elements, meta descriptions, structured data and image alt text, because they can appear in Search results.

Is there a special way to get into AI Overviews?

No. Google says there are no additional requirements or special optimizations. A page must be indexed and eligible to show in Search with a snippet.
