Define what your creative writing blog is for
Creative writing blogs serve several distinct purposes and each attracts a different audience. Options: sharing your own original work (fiction, poetry, essays), teaching the craft of writing to aspiring writers, documenting the experience of being a writer (the process, the publishing journey, the business), or a combination.
The most successful creative writing blogs are clear about their purpose — "I publish one short story per week" or "I teach character development for fiction writers" is more compelling than a vague creative writing catch-all. Define your purpose before you start.
