Sign up for a blog template, such as Wordpress, Blogger or Tumblr, and start posting regularly. Schedule a week’s worth of posts on a free day if you don’t have time to write every day.

Track your traffic and increase the type of posts that reel in the most visits, comments or re-posts. For tips, search your blog template’s Web site for free tutorials and forums.
