Interest Targeting is ad targeting based on broader interest categories inferred from user activity and engagement.
It matters because Reddit rewards relevance, authenticity, and community context. Brands that understand the platform’s terminology can build campaigns that feel useful to users instead of interruptive.
Example
An outdoor brand starts with an available interest audience related to recreation, then compares the resulting traffic with a more focused community audience. The category signals potential relevance; it does not establish that each reached person is currently buying equipment.
