I've started a blog about the post-secondary education system (hobgoblinminds.com) and have no real readership yet (single digits). What are the first real steps in gaining traction?
Make sure to stick to your targeted vertical, to ensure you're not spraying and praying with regard to content creation. If there's a focus, the traction points are that much clearer for both you and your readers/potential syndicators.
And always remember that there is a fine line between controversial and juvenile. Blogs can easily veer off the rails in this respect, resulting in not being taken too seriously.
