#1: User-Friendly Navigation: Keeping your blog easy to navigate with intuitive category labels will help people find the information they seek much faster. Also, make it easy for readers to leave comments and share your posts on various channels that will help lead others back to you.
#2: Commenting on Other Blogs: Look for other blogs in your industry that have a good amount of traffic and comments, and contribute a comment, but only if you think you can add value to the conversation. Be careful not to promote your blog here; just add some insight, and do it on a regular basis. Make seeking out and commenting on other blogs a part of your daily activities. The more you contribute to the conversation happening around you, the more you'll be seen as a thought-leader (and people will click on your link to check you out).
#3: Syndicate, syndicate, syndicate... share your content via all social channels always including Twitter, Facebook, Google+ and LinkedIn, which also makes it easy for others to share. And don't be afraid to do it more than once periodically sharing old posts via your social channels, especially those that were well received. Also let others freely repost your content with a link back to the original post.
