/r/ppc, /r/adops and /r/analytics These three tend to have a pretty high signal-to-noise ratio, particularly when asking very advanced and technical questions.

/r/ppc, /r/adops and /r/analytics These three tend to have a pretty high signal-to-noise ratio, particularly when asking very advanced and technical questions. From personal interactions I can vouch for there being many senior to exec level industry folks from a healthy mix of ad tech companies, networks, agencies, brands, etc. on both the buy and sell side. Everyone is pretty friendly, so while asking basic questions might just get you a link to go RTFM (and really the official docs are often the best starting point...) everyone is pretty friendly and helpful. Great for those trying to learn more about digital media and analytics all the way up to people with questions or who want to chat about stuff in the industry like header bidding, attribution, enterprise analytics troubleshooting, etc. And the best part is since we all are living and breathing advertising for a living, we have a pretty low tolerance for blatant sales plugs and content marketing spam like on some other subs.
