On October 1, 2026, Google updated its guide on using generative AI content. It now says it is critical to manually fact-check and review all AI-generated content before publishing, and that the review covers titles, meta descriptions, structured data and image alt text as well as the body copy.
What we know
- What changed: the "Using generative AI content" guide on Google Search Central. Google's documentation changelog lists the update on October 1, 2026.
- The new instruction: review AI-generated content by hand for accuracy and trustworthiness before it goes live.
- The reason Google gives: generative models do not look facts up. They predict a likely sequence of words from their training data, so they can produce false statements that read as true.
- How far the review goes: titles, meta descriptions, structured data and alt text are included, because they can appear in search results.
- Why now: Google says it added information from its Search Quality Rater Guidelines and wanted the documentation to match what it presents at developer events.
- On the same day, the people-first content guide shows as updated. It includes a warning against fabricated author profiles (AI-generated headshots, made-up names or false credentials), which Google calls deception and a signal of a low-quality page. It also has a section defining what counts as a page's main content. Search Engine Journal compared it with an archived June version and pointed out both additions.
What changes and what doesn't
The basic rule stays: using AI is not banned and is not penalized on its own. The guide still says that generating many pages without adding value may violate the spam policy on scaled content abuse.
What is new is that human review is now a written instruction, and that it reaches the parts of a page few people check: the title, the description and the alt text.
This is not an algorithm change. It is documentation: it describes what Google expects from publishers and does not announce a ranking update.
How to tell if it affects you
It affects you if you publish copy, product descriptions, titles or alt text generated with AI and nobody compares them with a source. Five checks:
- Every figure, date and name has a source that someone opened and read.
- The title and meta description say the same thing as the page.
- The alt text describes what is actually in the image.
- The structured data matches the visible text (price, date, author).
- The person in the byline exists and the profile is real.
How we apply it at DomHostSeo
We use AI to draft and to illustrate, so we had these rules written down before the change. No news item goes out on another outlet's word alone: we open the primary source, here Google's two guides and its changelog. Figures about our own data go through an automatic check that blocks publication when they are not backed up. AI-made thumbnails carry a metadata tag that says so, and we write their alt text while looking at the final image. A person always makes the decision to publish.
It is the same approach we took with the September spam update, which targets mass-produced content.
