You've decided you want to blog, but you should have some clear idea of what your blog is going to be about. Perhaps you love cooking and want to share recipes and cooking tips with others. Maybe you are really into sports and want to share about the world of sports.

Whatever your blog is about, it should be clear to your audience the purpose of the blog. If it's too confusing or has too much random content put together into one blog, then it may turn away readers.

Wordpress allows you to set up as many blogs as you want, so if you are really passionate and excited about several different topics, you have the opportunity to create a blog devoted to each one. This will allow you to blog about them all, but still keep them separate and generate readers who follow the blogs they like.
