All of FB's users are logged in and can be targeted by interest.
reddit also houses tons of NSFW and controversial content which probably scares some companies away, even if their ads won't show up there.
- you want to advertise B2B software to small/medium business owners.
- you want to advertise expensive fashion items to 20-35 y.o. women in NY/CT.
Will you pick FB or reddit? And then yes, lack of brand safety for non-targeted ads.
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.
Rethoric question.
I used to post my DNS-host (dns-api.com) on /r/sysadmin, for example.
Instagram, every day of the week.
Thats just my perception though - also that reddit as a whole is very lowest common denominator tech/business wise.
However, I think the real money would be for them to be more like Craigslist. Subreddits could pay to upgrade to become more feature-rich "Classified"-like pages whose posts could then be further boosted (re: upsell for ad team) across other subreddits.
Users react with hostility to forced social media / redesigns geared to ad revenues. They like new features that are actually useful and enhance the experience.
Maybe they have exceptionally high operating costs? Or are they just really bad at selling ad space? I get that there are some advertisers that don't want to go on there because they are afraid their ad will show up next to a picture of a naked lady (which is something Reddit could control pretty easily), but Reddit is so big that it seems pretty hard to ignore.
