Community targeting allows you to reach users based on:

Community targeting on Reddit Ads leverages users' engagement with specific subreddits. This allows advertisers to reach highly relevant audiences based on their declared interests and discussions within those communities. For example, targeting users active in r/fitness would be ideal for a sports equipment brand. Location and demographic information can be used in other targeting methods, but not specifically community targeting. Reddit Ads does not access or utilize users' purchase behavior on Amazon or their search history on Google for targeting purposes, as this data is external to the Reddit platform.
