Write about something you know. If you don’t know much about a specific topic, invite an expert to write about it. Having a variety of authors in your blog is a great way to keep visitors engaged. You know your audience better than anyone else, so keep them in mind as you write your blog posts. Write about things they care about. If you have a company Facebook page that gets lots of comments, you can look here to find topics to write about.
