What is the 30% rule for AI content in SEO?

There is no official 30 percent rule for AI content in SEO. Google has repeatedly stated it does not have a numeric threshold for how much AI generated content a page can contain, and it judges content on quality and helpfulness regardless of how it was produced.

The 30 percent figure circulating online, along with variations like 70 30 or 20 60 20, appears to be an informal guideline some marketers invented rather than an actual Google policy, and no Google representative has confirmed it in any public statement.

What Google's own guidance does say clearly is that content made primarily to game search rankings, whether written by a human or generated by AI, violates its spam policies. Focus on usefulness and accuracy over hitting any invented percentage.
