I see this misconception all the time - no official documentation says AI tools are designed to churn out ready-to-publish content without human oversight. google's own guidelines are pretty clear: mass-producing low-quality, auto-generated pages just to game rankings is a spam violation.
There's scaled content abuse to watch out for - publishing huge volumes of thin, automatically created pages that add nothing new. The bigger risk is factual inaccuracies. Hallucinated claims in sensitive niches get slapped hard by the algorithm.
Best practice is to have a subject matter expert review and edit AI output for accuracy, tone, and brand alignment. Also infuse the content with first-hand experience, unique data, or specific examples that no AI can fake.
so regardless of what you think about Google's investment in Gemini meaning you can use 100% AI content and rank well - their own advice contradicts that.
