Does Google penalize AI-written blogs?

Google's official position, stated in their March 2024 Helpful Content Update, is that AI-written content is allowed. The penalty is for content that is generic, unoriginal, or created at scale to manipulate rankings. That description fits a lot of AI-written content, but it also fits a lot of human-written content. The tool is not the issue.

The Helpful Content system actually punishes:

• -Sites publishing dozens of articles per day with no editorial layer (the obvious AI dump pattern).
• -Articles that paraphrase the existing top 10 results without adding a new angle, data point, or perspective.
• -Pages stuffed with keywords but missing first-hand experience or original research.
• -Topical drift: a site about plumbing suddenly publishing 50 articles on crypto.
• -Hallucinated facts, fake citations, or factual errors that erode trust.

An AI draft that gets a real human pass, includes original data or examples, and stays on-topic for the site performs the same in Google as a fully human-written article. A bulk AI dump gets demoted, and so does a bulk human-written content farm. The line is effort and originality, not authorship.
