Equally important is to harmonize your business name with your blog name. For example, when I first started my blog, my business was called Customized Newsletter Services. The blog was my communications center for everything about e-newsletters for coaches, so I called it CoachEzines.com. When things evolved, the blog evolved into blog writing for small businesses, so I changed the name to Writing on the Web.
Ah, you see why there are days when I wish I could start over. I didn't think things through 4-5 years out into the future. Don't make these branding mistakes like I did.
