*Core concept* · *Social Search*

## Definition

The social corpus is the aggregate body of social media content — posts, videos, comments, profiles, threads — that has been indexed by AI systems and is available for retrieval when generating social-sourced answers. It is the social equivalent of the web corpus used in traditional search.

## Why It Matters for AI Search

The social corpus is an increasingly important retrieval source for AI systems, particularly for recent events, product opinions, practitioner advice, and consumer behavior questions. A brand with a structured, keyword-rich, entity-consistent presence in the social corpus — across multiple platforms — has a social retrieval footprint that complements its web-based [entity signals](https://www.platelunchcollective.com/services/entity-seo). Building social corpus presence requires treating social content with the same structural rigor applied to web content: entity references, descriptive captions, keyword-optimized titles, and organized archives.
