I am working with a client who writes about children and their back to school issues. She is concerned that she will only be able to sell her eBook for a few months of every year. I encouraged her to expand her area of expertise to children’s issues all year long, such as summer vacation, transitioning from elementary to middle school, and dealing with bullies at school. These are all areas that she is knowledgeable about and are of interest to parents everywhere. What happened to this writer was that her niche became too narrow. While it is more profitable to write for a specific niche, be careful about limiting yourself too much. It is best to spend time researching your market and asking them what they want to know. They will tell you and then you can write eBooks that are both helpful and profitable.
