Reach is the number of unique people exposed to an ad or piece of content.
Example of Reach
A campaign reaches 5,000 people and records 15,000 impressions in the same reporting period. Reach describes the audience exposed; impressions include repeated exposures, so adding the two numbers would not produce a meaningful audience total.
Why Reach matters
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.
