Since helping people use blogs for sales and marketing is my business, I thought I would chime in.
Well done, blogging can allow a small company to do what a larger company with millions to spend on marketing could never achieve. Some of the direct benefits of blogging are:
1. Better Google Rankings
2. Increased exposure
3. Get your message out directly to your audience
4. Build trust and credibility
5. Enhance your company's image
6. Conversation with your audience.
After you make sure your boss or company says a blog is OK (which may end up being the hardest part), I recommend that you:
1. Think very hard about the people in your market, who they are and what they are thinking. Specifically, understand what problems you solve for them. Important: express these problems in their words, not yours, and express them using words and phrases they would use in normal conversation.
2. The content of your blog should be addressed to (and written for) those people and problems. You want what you write to resonate with them so much that they say "It's like Jessica knows me". Forget 'marketing-speak'. Write it like you are talking to a friend.
3. Use Google Blog Search and those words/phrases you came up with in step 1 to find conversations on the internet and join them. When you join the conversation, DON'T SELL. Simply offer advice and help. If your sig line or the comment form's URL field contains a link to your blog, interested people will naturally be drawn back to your blog and will read it.
None of this is rocket science, and it works. It is merely taking the activities you do in your normal face-to-face networking and extending them globally. Think of it as Networking On Steroids.
