Thin Content
In one line
Thin content is content that adds little or no value for users — shallow, duplicated, or auto-generated — and it tends to get downgraded under Google's quality systems.
Going deeper
Thin content isn't just about word count. AI-spun comparison posts, category pages that copy the product description verbatim, one-paragraph 'definition' posts — anything where the user takes nothing away qualifies.
Google's Helpful Content system and core updates have steadily demoted thin content. Even a localised cluster of thin pages can drag domain-level signals, which is why pruning beats hoarding.
It's even clearer in GEO. LLMs evaluate citation candidates sentence-by-sentence for factuality and depth, so thin content is effectively removed from the citation pool. Refining beats churning out volume.
