There are a lot of ways to promote you blog. Looking back, I have been using Google Plus as an effective way to share the blog articles. It actually helped to surge my views on my blogs. Since I have a niche blog about mainstream music, I tagged the artists and hashtags, which has drawn views from fans of the artists. I also used Twitter, and using an appropriate hashtag can draw traffic to your website. Facebook won't help that much though, based on my observation.
