How do you decide what you will blog about? 

Consider Your Purpose
Are you blogging to build your business’ visibility?  Are you blogging for PR?  Is blogging a way to gauge customer interest and satisfaction?  Is it a way to deliver information to your employees or your customers?

Consider Your Audience
Who reads this blog?  Who do you want to read this blog?  Why do they read it?  What would make them read it more?  What do they want and need from you?

Consider Your Content
What do you want to do with your content once you’ve blogged?  Could you turn it into eBooks?  What about compiling it into a book for print publishing?  Maybe you want to highlight your best posts on a ‘resources’ page?
