When I was first starting out, I promote the hell out of my page. Now I don't have to do anything except upload new tracks and I shoot up the charts.
Trust me, put in the time/effort to promote your page (via paid promotion, myspace bulletins, myspace comments and messages, etc) and soon it becomes automatic once you get known enough.
A little bit of SC knowledge (from an SC guru
)
1. Get yourself a domain and forward it to your Soundclick page. I got mine from godaddy.com for $9/year. Mine is 110beats.com, my partner/friend is blackfrostwhp.com
2. Get a Soundclick VIP page and have your contact information and payment options clearly visable
3. Use myspace to your advantage. I even went as far as to getting FriendBlasterPro and added hundreds of rappers, then left em comments saying I was a new producer on the scene, gave em my URL and told em to hit me up if they ever needed production. Every so often I'd send out a few bulletins, say, whenever I upped a new song or had a new "sale". Put your SC player on your myspace page and have it automatically play.
Those are just the basics, I could write a god damn book on how to be successful on SC. Maybe I will
