Thin Content
Pages with little unique value, a specific category Google actively demotes.
Thin content is content with little or no unique value — auto-generated text, near-duplicates with minor variable swaps, scraped content, doorway pages, or pages that exist only to rank rather than to help users. It's explicitly named as a manual action category in Google's webmaster guidelines.
Context
Thin content is a site-wide quality signal. A site with many thin pages will underperform even on its high-quality pages because the site-wide signal drags everything down.
The 2024 Helpful Content system update and subsequent core updates tightened this considerably. Sites with large numbers of thin pages saw 30–80% traffic losses; many never fully recovered.
Programmatic pages with 200 words of content where 180 words are identical across the set and only the city name changes are textbook thin content. The fix is deepening the per-entity data, not adding more words.
Word count alone isn't the signal. A 300-word piece of unique, useful content is fine. A 2,000-word piece of AI-generated filler with no unique insight is thin.
