r/mealprepsunday would be an example of which type of targeting?

The subreddit r/mealprepsunday is a specific community on Reddit, making "Community" the correct targeting type. Reddit Ads allows advertisers to target users who are members of or actively engage with particular subreddits. This is distinct from broader "Interest group" targeting, which might encompass a wider range of related subreddits or user behaviors without focusing on a single community. "Interest sub-group" is not a standard Reddit Ads targeting option. "Device" targeting focuses on the hardware users are accessing Reddit from, not their content preferences.
