Google doesn't ban generative AI, and it doesn't penalize a page just because a neural network wrote it. The current Search Central guidance holds AI generated content to the same bar as anything else: it has to meet Search Essentials and Google's spam policies, regardless of how it was produced (see developers.google.com/search/docs/fundamentals/using-gen-ai-content). The same page is explicit that using generative AI to publish many pages without adding value for readers falls under the scaled content abuse spam policy — the risk is the volume-without-value pattern, not the tool. For automatically generated content, Google asks for accuracy, quality and relevance, covering not just the body text but titles, descriptions and structured data too, and recommends telling readers how a piece was created when that's useful context for them.
This article draws on Google's own documentation because it's the primary search engine for English-language markets. Yandex, which serves the Russian-language market, states a comparable principle in its own webmaster help — automatically generated content that gives users no value is listed among the signs of a low-quality site — but that guidance is written for a different regional market and isn't the source used here.
Both documents point to the same conclusion: what matters is not how a text was produced but whether it's useful to the reader and whether it stays within spam and scaled-content policies. Neither document names a specific ranking penalty, a traffic loss, or a percentage tied to AI content on its own — no official source gives a number like that, so this article doesn't invent one. A section too short to cover the topic hurts for the same reason — see how to expand a short article.
