Twitter for exposure and traffic. Typically links and hashtags for best results. Tweet often.
LinkedIn for promotion (promoting self or business) and leads. You can post in groups, answer questions you’ve made posts on and update to your LinkedIn feed. This works more for b2b because of the platform but if you have a blog like SME where it’s more educational, that can work really well.
Facebook for engagement and leads. Try asking a question about the post to help get your audience engaged on Facebook and possibly in the mood to leave a comment or share.
These are just a few social sites I’ve used that I know work and how I’ve found them to work most effectively. There are other things like SEO which was sorta mentioned in previous posts (long-tail keywords) and what I think Glen was referring to… guest blogging.
Guest blogging works if the blog you’re posting on is well established.
