Your business blog serves several purposes for you; boosts traffic, customer service; marketing.  But one thing we forget is that the business blog is a form of news, journalism.

Content is king online and your content sets your entire site apart from others.  A good blog can really propel a site to prominence.  In contrast, a poorly written blog, or one with excessive advertising does your business a grave disservice.

Be sure your blog reflects well on your company.  Keep the content fresh, the commentary professional and conversational at the same time, and respond to your comments.
