Google Emphasizes: Manually Verify AI-Generated Content Before Publishing

Google's September 2026 spam update entered a second wave after being announced on September 24, 2026, with a rollout window that could extend for two weeks. Activity resurfaced around September 30, as observed by SEO specialists, meaning that site rankings may remain subject to fluctuations over the coming days.

In a separate development, Google updated its guidelines regarding AI-generated content, stressing that it is "critical" for publishers to manually check and review this content before publishing, in a clear emphasis that final responsibility remains with humans rather than the tool alone.

The company added new sections addressing "main content" within its "people-first content" documentation—guidelines directing publishers to offer original material that serves the reader rather than low-quality filler targeted solely at search engines.

This emphasis comes while the spam update is still rolling out within its timeframe, meaning that sites relying on automated generation are required to review their content twice: once against ranking fluctuations, and once against the new quality guidelines that insist on human oversight prior to publication.

What do these terms mean?

**Spam Update:** A modification made by Google to its systems to downgrade the rankings of sites using deceptive practices or low-quality content. **AI-Generated Content:** Text or images produced by automated tools, requiring human auditing to verify accuracy prior to publication. **"People-First" Content:** Google guidelines that favor material written to genuinely benefit the reader rather than merely satisfy the search engine.
