All your good blog writing doesn’t mean anything if nobody reads it. The first purpose of your blog is to supplement your resume. Give someone who already knows about you a place to find more information. Achieving that purpose is simple: put your blog URL on your resume.
Letting other people find you through your blog is a much larger issue. Remember, you aren’t trying to make money with your blog nor are you trying to become a pundit or a public personality. You just want to increase the chances someone will stumble on you. There are three websites to look at for advice about popularizing your blog:
ChrisBrogan.com has specific advice about making your blog better and more useful. He organizes it all into a section called My best advice about blogging. This will show you how to organize your blog and make it understandable to readers.
Copyblogger.com is focused on helping you improve what you write in your blog. How you say something is almost as important as what you say.
Problogger.net has general advice for improving the marketability of your blog.
