Sharing more posts with better images
Images play an important role in blog post. I suggest that every blog post have at least one image but more is better. The Image you providing should describes what the blog post is about.
Give people multiple options to share
It is nothing about the sharing icons placement in the blog post. Most of the people display Twitter, Face book and Google+ sharing icons in the post.
Increase Followers & Fans
Provide Newsletter subscription feature in the blog post readers and grow followers/fans directly to your site.
Share Blog Post with relevant content in Social Media Platforms like face book, Twitter, Google plus and etc.
