By John Miley, Senior Associate Editor May 7, 2012 You won’t get rich as a blogger, but even a part-timer can make $100 a month or more. More visitors mean more cash.SEE ALSO: 11 Ways to Get More Cash Start by picking a topic you’re passionate about -- the more specific, the better (for example, “fly fishing in Montana” instead of “fly fishing”). 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. Above all, be original, says Jessica Quirk, blogger at WhatIWore.Tumblr.com. “You really have no hook without original content,” she says. Use social media to attract a community and keep them engaged. As your audience grows, post advertising. Google’s Adsense, a free program that lets you embed ads on your site, gives you a cut of the profits. 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.
