Instead, make your blog somehow related to your business, but not about your business. For example, an auto repair business should blog about automotive topics, like the importance of regular maintenance or how to inspect tires for excessive wear. Blog entries that help your customers understand and enjoy their cars will attract people to your blog. They'll get the idea of visiting your business on their own, since you'll have links to your main web site prominently displayed.
Similarly, a dental office blog should be about understanding and caring for teeth, not about the specifics of that dental office. Again, that information belongs on the main web site. Articles about the importance of early dental care for chidren or informative articles about common dental concerns are the best blog topics for this type of business.
That's not to say that an occasional article about the business itself isn't in order. If you're having a special event or a change of address, an article about that is a good idea. But such articles should be well mixed with informative, entertaining articles about topics related generally to the type of business you operate.
At the end of each general blog entry, you can also include a short paragraph inviting readers to contact you for more information or to schedule an appointment related to the topic of the blog. These paragraphs should not be more than a sentence or two, and should contain links to your web site and email address.
Remember, you're aiming at a balance between informing and entertaining your blog visitors and putting them in touch with you. If you attract them to your blog by offering useful information, they'll naturally think of you when they want to shop or obtain related services. That's the way blogs work to help you build business.
