Interest Targeting

Interest targeting reaches people by inferred interest categories, like technology or personal finance, based on what they engage with across Reddit.

You pick from Reddit's interest buckets, and it serves your ad to users whose activity across many communities signals that interest. This casts a wider net than naming subreddits, so it is a top-of-funnel move when you want scale beyond a handful of communities. Reddit handles the inference from behavior.

Say you sell budgeting software. Community targeting limits you to a few finance subreddits, so you add the personal finance interest category and reach people who engage with money topics all over Reddit, not just in those rooms. Volume climbs, and you compare its cost per result against the community ad groups to see if the wider net holds up.

Interest is inferred, not declared. These buckets are Reddit's read of behavior, so they run broader and looser than community targeting, and cost per result can slip if you do not watch it. Treat interest as reach and let communities carry the precision.

Wider net, looser aim. Know which you need.
