Sone great points, courtesy of Entrepreneur.com, that make the case for starting a business blog.
A blog allows your business to engage with current and potential customers in a direct, informal, no-pressure way. You can communicate the strengths of your product or service, the expertise of your top executives and the breadth of your company's experience in ways that traditional marketing and advertising don't allow. This can help engender a better understanding of your company as well as inspire customer loyalty.
Because of its collaborative nature, a blog can help you gain insight into customers' needs and interests. You can then use this information to develop new products or services or fine-tune existing ones.
A blog can make your company appear more "alive'' and approachable. A website promoting your products or services is an essential marketing tool. But a blog, in effect, gives your company a personal voice, which also can help boost customer loyalty.
Blogs cost little, if any, money. Some public blogging sites are free; others charge only nominal fees. Also, blogs are often extremely easy to set up and update, with virtually no training required.
