Create your own website, it's not as difficult, daunting or expensive as many people think.
Have an 'About Me' section, tell a story, be more than a beat in a typical and or boring layout.
By all means, link to your sound cloud account YouTube account, twitter even sound click and have them link back. Make it clear that the site is where you do business.
Be interesting..... soundcloud is a vanilla music hosting service that is about straight no frills music (and a bit of a circle jerk at times) but you can provide links in your profile to your website, twitter etc.
Sound click can be customized to the point were you're just another pretty soundclick page looking for that PayPal lease.
It's up to you and no one thing is going to guarantee success .... but I would rather have a well prepared, concise resume than thinking 'my music speaks for me" there are tens of thousands of brilliant and talented beat makers out there thinking the same thing. Never underestimate professionalism and where it can get you. It's one thing many people lack.
