Subreddit Discovery
Definition
The systematic process of identifying which subreddits are most relevant to a brand's target audience, category, or use case. Discovery methods include Reddit's internal search, third-party overlap tools, and audience ethnographic research.
Context
Tools mapping subreddit audience overlap are particularly useful for discovery. If r/[Community A] has significant member overlap with r/[Community B], users active in one are likely active in the other — meaning a brand successful in one community can extend to the other with relatively low additional discovery effort. Subreddit Stats and similar tools provide overlap visualizations built from Reddit's public activity data.
Relevance to Reddit
Subreddit discovery precedes every Reddit marketing program. Brands should map potential communities by audience relevance, community health, posting rules, and receptiveness to brand participation. This research typically surfaces a tiered landscape: primary target communities, secondary communities, and adjacent communities — each requiring a different participation approach and timeline.
