Starting your blog.
As a business the most important aspect of your blog is that it speaks with a singular voice/personality. Your choice of writing style will reflect how readers perceive and respond to your content and (if done correctly) will establish a deeper connection to your customers. This personality can take many forms and for most businesses originates from their core values. If your company is fun and outgoing you may chose to WRITE KEY PHRASES IN ALL CAPS to emphasize the energy or excitement they express. you may write in all lowercase letters to identify with a younger audience that has grown up with text messaging. And so on.

Try on a few personalities.
There are as many different choices as there are people in this world. Writing your blog post ahead of time in Notepad or Word will help you to think it over before you commit it to the web. You should never feel pressured to write about what to write, just let it come out and than edit it later. There's nothing worse than rushing a post that no one reads or comments on. DON'T RUSH.

Be sure to set realistic goals.
Most of us won't be an overnight blogging sensation. Building a consistent stream of traffic takes time and commitment, but once its established your visitors will be a self perpetuating network of 'a friend of a friend.' Don't commit to writing once a day if you lack the time. Instead write every two days or once a week. Once you start you'll find that subject matter will gradually become more easier. Don't forget to keep it relevant, but don't sell either. Find ways to bring your message around to how it relates to your industry and your customers will thank you. If you sell carpets, write about the newest spot remover that's a household sensation, post photos of a sculpture in France that's made of carpet or why most modern homes are no longer built with hardwood flooring.
