Pages with little or no original value to users, including very short pages, auto-generated content, scraped content, and doorway pages.
Thin content refers to web pages that provide little or no unique value to the user. Google identifies several types of thin content: automatically generated text with no original contribution, scraped or copied content from other sites, doorway pages created solely for search engines, and pages that are too short or shallow to meaningfully address their topic.
The Google March 2024 spam update expanded the definition of thin content to explicitly include AI-generated content published at scale without adding original value. This directly targets autoblogging tools that produce high volumes of generic AI text.
Thin content can result in Google penalties ranging from individual page suppression to site-wide ranking drops. The March 2024 update specifically deindexed hundreds of sites engaged in "scaled content abuse," which Google defines as generating large amounts of content primarily to manipulate search rankings.
This makes quality controls essential for any AI content strategy. Publishing 1,000 thin AI articles is worse than publishing zero, because the penalty affects your entire domain.
Acta AI's 10-stage pipeline is designed to prevent thin content. The SERP analysis step ensures articles cover what top-ranking content covers. The AI review step catches shallow or generic output. The Acta Score flags low-depth and low-originality content before publishing. The banned phrases system (186 phrases) removes AI filler language that is a hallmark of thin AI content.
A site publishes 500 AI-generated city guide pages, each with the same template and no local-specific information beyond the city name. Google classifies this as scaled content abuse and deindexes the entire site.
