Can you not pick specific subreddits to advertise in (or have your ad appear next to on the home page)?

Seems like your userbase self-segments pretty quickly on Reddit, although it's no doubt a fulltime job for several engineers to keep up with the classifications on subreddits.

I guess the biggest problem is that so many users don't log in and just browse the default, which is pretty generic. Reddit could track the not-logged-in users and what they click on like Google, but that's a fair bit more work.

How efficient are subrrddits compared to always logged-in audience which told you their age, interests a location, explicitly?

Rethoric question.

Yes, you can target subreddits.

I used to post my DNS-host (dns-api.com) on /r/sysadmin, for example.
