Which of the following is a good strategy for using blogs to promote products and services?

a. Write in a style that is personal and conversational; minimize direct promotion of your products and services. Focus instead on topics your customers and potential customers find helpful and interesting.

b. To cut through the noise in the blogosphere, promote your products and services constantly. If you don’t, your competitors will drown you out.

c. Make sure the blog matches all other corporate communications in both style and content; customers get confused when a company communicates in more than one style.

d. Blogs should never be used for marketing and selling.
