Pick an engaging Topic
You want to excite the reader and leave them hanging off every word. To do this, you need to choose a topic that resonates with your target customer. Something they care about.
Don't recreate a company blog post or rehash marketing material. It would help if you showcased your level of expertise in creative way. You can do topic research for your book by asking customers what they care about. Ask them in person or do a Google search to find the most searched terms. Then choose a cover design that relates to that topic, and you will be onto a winner.
