Is Google Quietly Penalizing AI Content? One Manual Action Suggests So!

Google has issued a partial manual action against WindowsForum.com for “Thin content with little or no added value,” affecting more than 168,000 discussion threads and over 500,000 forum posts.

What happened?

A Google manual action notice was posted by the site owner on Reddit in mid-July, 2026. The message read, “thin content with little or no added value” and singled out over half a million posts in one section of the site. It was a partial manual action, as the other parts of the website didn’t lose their ranking eligibility.

What caught SEOs’ attention? The flagged posts were from an AI chatbot that the forum had been operating since 2023 and had made more than a hundred thousand responses to forum user queries, and was listed as a forum member.

Google has yet to officially confirm that AI authorship caused the action. However, Australia-based SEO consultant Gagan Ghotra mentioned that the AI Chatbot must be the reason the content was rated thin.

Google Still Says AI Isn’t the Issue

Google has not changed its position on AI-generated content. The company continues to maintain that content is not penalized simply because it was created using AI. As Google’s Search Liaison, Danny Sullivan, has repeatedly stated over the years, what matters is the quality and usefulness of the content, not the method used to produce it.

It was the enforcement that changed. One of the top targets of the March 2026 core update is “scaled content abuse”, which refers to many pages of low-quality content, generated by humans or AI. Traffic dips of up to 80% were seen for sites where unedited AI content was mass-published. AI with human editing seems to have been a winner at sites.

An Ahrefs study found that 600,000 top-ranking pages contained 86% of AI-generated content, with little to no correlation between AI usage and search rankings. The findings suggest that AI itself is not the ranking issue. Instead, content that is thin, repetitive, or published at scale without meaningful editorial value is more likely to come under Google’s scrutiny.

Why It Matters?

The WindowsForum.com case does not introduce a new Google policy. Google’s scaled content abuse policy has been in place since 2024, targeting content created at scale primarily to manipulate search rankings, regardless of whether it is produced by AI or humans. The recent manual action indicates that Google continues to enforce these quality standards, even against long-established websites.

Key Takeaways!

☑ AI-generated content is not automatically penalized by Google.

☑ Content published at scale without original value or editorial oversight may be classified as thin content.

☑ Human editing, first-hand expertise, and unique insights remain important signals of quality.

☑ Google’s focus continues to be on content value, not the method used to create it.
