Facebook - Put links to your other social media accounts in your description. This will help your fans to find out more information about you. Always have a link to your webpage and your Twitter handle. Post different pictures or comments promoting people to link to your other accounts.
Twitter - Use short inspiring tweets to promote your followers to go to your website or other account. Use a sales promotion through twitter like the first 10 customers to make a purchase mentioning the tweet gets 10% off.
Tumblr - The best way to promote other sites through Tumblr is by using eye catching or interesting pictures. Make sure you label it with the appropriate tags by checking to see what's actually trending.
Google + - So I'm not exactly a professional when it comes to Google Plus. Honestly, I don't really like it - but I really want to like it. It seems easy enough to post videos, status updates or pretty much everything that Facebook allows you to do. I like how it automatically connects your You Tube account so people in your circles can see what great videos you've been watching.
Posterous - Not too many people use this site just yet but it's great for auto posting to your other social media accounts. You can link this up to your Twitter, Facebook, Fan Pages and a whole bunch more. It makes it easier to organize your posts and saves you time in the long run.
