wow old post no answer. yes to promote content. I have used a little. however, I need more videos more content more artists before I do it again. or else there is no benefit. Rule of thumb some say 30. But I say 100 or more videos, then you can advertise, I would be careful. stay with in a budget even if its ten bucks advertise for ten bucks. it does bring taffic however retention of traffic is a different story. far as backlinks I am about to ask TB, if I do not find a thread on this.
side note, if you have a lot of money advertising is a great way to grow, because all that traffic you will get some people to stay. keep doing it you get more and more. but this is not logical, because you will waste ALOT OF MONEY for nothing, this scenario is if you got lots of money to burn and you don't care.
