A blog allows you post content in the form of text and pictures and engage in a dialogue with people commenting on your posts. You can control which comments actually appear on your pages by approving, deleting or marking them as spam, using your preferred blogging software.
Blogs can be written in many styles, from informal and personal, to professional and corporate. As a small business, it is important to inject some personality into your blog, so that your followers get to know you, as well as read your material.
