Google's AI content guidance: how to fact-check before publishing
Google's October 2026 update asks publishers to fact-check AI content, including titles, meta descriptions and alt text. Here's a simple review workflow.
Google does not penalise content just because AI helped write it. What it does expect, and now says more plainly, is that a person checks AI-generated content for accuracy before it goes live, including the bits most teams forget: page titles, meta descriptions, structured data and image alt text. On 1 October 2026 Google updated its guidance on using generative AI content to make that fact-checking step explicit.
This guide explains what changed, what has stayed the same, and a simple review workflow you can use whether you publish two blog posts a month or two hundred product descriptions.
What Google changed in October 2026
Google's Search Central changelog lists an entry on 1 October 2026: "Updated guidance on using generative AI content", adding information from the Search Quality Rater Guidelines. At the time of writing (November 2026), the guidance page makes these points:
- Fact-check everything. Google explains that generative models predict likely sequences of words rather than retrieving facts, so they can produce confident errors. It asks publishers to manually fact-check and review all AI-generated content for accuracy before publishing.
- Metadata counts too. The same review applies to title elements, meta descriptions, structured data and image alt text, because these can appear directly in search results.
- Scale without value is the risk. Using AI to generate many pages without adding value for users may violate Google's spam policy on scaled content abuse.
- Rater guidelines as a reference. The page points to the rater guidelines sections on scaled content abuse and on content with little effort, originality or added value. Google is clear that rater scores do not directly affect rankings, but the sections describe what low-value content looks like.
A few days later, on 5 October 2026, Google's page on creating helpful content was also updated. It still encourages accurate bylines where readers expect them, and now says to avoid deceptive authorship information. In practice: don't invent author personas for AI-written posts.
What has not changed
The underlying position is the same one Google has held since it introduced the scaled content abuse policy in 2024. The policy applies however the content is made, whether by AI, by people, by scraping or by stitching together other sources. The question is whether a page helps the reader, not which tool produced the first draft.
Google's helpful content page still frames this as "Who, How and Why": is it clear who created the content, how it was produced (including whether automation was used), and why it exists? If the main reason a page exists is to rank rather than to help someone, that is the problem, with or without AI.
Treat AI as a fast first-draft writer that needs an editor, not as a publisher.
A practical fact-checking workflow
Most small teams don't need a heavy editorial process. They need a short, repeatable checklist that someone owns. Here is one that works for blog posts, service pages and product copy.
- 1 Start from your own material. Give the AI tool your notes, product specs, pricing page or interview transcript. Drafts built from your own source material contain fewer invented details than drafts written from a one-line prompt.
- 2 Mark every factual claim. Before editing for style, highlight each number, date, product feature, price, legal statement and named source. These are where AI errors cause real damage.
- 3 Verify against a primary source. Check each claim against the vendor's documentation, the official announcement or your own records. If you can't verify something quickly, remove it.
- 4 Add what only you know. Include your process, examples from your work (without naming clients who haven't agreed), photos you took, or a clear opinion. This is the "added value" that separates a useful page from a generic one.
- 5 Review the metadata separately. Read the title tag, meta description, alt text and any FAQ or product schema on their own. AI tools often generate these in bulk and they are rarely checked.
- 6 Put a real name on it. Publish under the person or team who reviewed it. If automation played a large part, say so in a short note where readers would want to know.
Where AI content tends to go wrong
From the guidance and from common publishing mistakes, these are the areas worth extra attention:
| Content type | Typical AI error | What to check |
|---|---|---|
| Blog posts on software or regulation | Outdated versions, wrong dates, features that don't exist | Official changelogs and documentation, dated at the time of writing |
| Product descriptions | Invented materials, sizes or certifications | Your product data and supplier specs |
| Location or service pages at scale | Near-identical pages with the city name swapped | Whether each page has genuinely distinct, useful information |
| FAQ and product structured data | Answers that don't match the visible page | Markup matches on-page content and validates |
| Image alt text | Generic or keyword-stuffed descriptions | Alt text describes what the image actually shows |
AI images and product listings
If you sell online, there is a second set of rules to know about. Google's guidance notes that Merchant Center's policies require AI-generated images to carry IPTC DigitalSourceType metadata set to TrainedAlgorithmicMedia, and AI-generated product data such as titles and descriptions to be specified separately and labelled as AI-generated. Many image tools add this metadata automatically, but editing and compression steps can strip it, so check the files you actually upload.
For general site content, Google suggests that adding image metadata and short disclosures can help give readers more context about how content was made. If you also serve visitors in the EU, read our guide to EU AI Act transparency rules for websites, which covers separate legal labelling duties.
Should you disclose AI use?
Google does not require a label on every AI-assisted blog post. Its helpful content page says AI or automation disclosures are useful where someone might reasonably wonder how the content was created. A sensible rule for most businesses:
- No disclosure needed for light help, such as an outline, grammar fixes or a rewritten introduction, where a person did the research and editing.
- A short note is worth adding where most of the text was generated and then reviewed, for example "Drafted with AI assistance and reviewed by our team".
- Clear labelling for anything largely automated, such as data-driven summaries or AI-generated images that could be mistaken for real photos.
Frequently asked questions
Does Google penalise AI-generated content?
Not for being AI-generated. Google's spam policies target content produced at scale mainly to manipulate rankings, however it was made. AI content that is accurate, reviewed and useful is treated like any other content.
Did the October 2026 update introduce a new penalty?
No new ranking signal or penalty was announced. The update made the expectation of manual fact-checking explicit and brought in references from the rater guidelines.
Do I need to fact-check meta descriptions and alt text?
Yes. Google's guidance specifically lists title elements, meta descriptions, structured data and image alt text, because they can appear in search results.
Can we use AI to write hundreds of location pages?
You can use AI to help, but pages that differ only by a swapped place name and add nothing useful are the kind of thing the scaled content abuse policy describes. Each page should offer genuinely local or specific information.
Need help with AI content workflows?
We set up AI-assisted content workflows that keep a human review step built in, from prompt templates fed with your own source material to checklists for metadata and structured data.
