Spend at least an 30mins on every social media accounts you have. Try sharing, liking or commenting to your friends posts.
Hard to do if you are active at several Social Media sites. You have to leave some time in your schedule for work, after all. 
In my experience, I find the best way to reach new people is through comments on your contact’s posts. Sharing is good, but it only lets your friends and original poster know about what you have shared. Likes are great way to keep connections and can possibly expand your network if you ‘like’ the comments of others in a post, but just liking a friends post–I don’t see how that expands your network. Same as retweets on twitter.
Moreover, shares and retweets may not post anything from you that your friends probably haven’t already seen elsewhere.

Strategies differ from one platform to another. For Twitter: tweet regular interesting tweets. Follow influencers or your target audience. But, remember not to tweet too many.
For Facebook: Add people and share updates about your product/service from time to time. Also you can start FB ads. For LinkedIn: Connect with important people, add yourself to groups and initiate or take part in discussions. Still not sure with Google+ though as it is relatively new.
For me I just keep it up with new and fresh information everyday in that way I can more value to my website.
