Take into consideration these factors when thinking about the revenue your writing career may generate:
Are you writing about what you know? Unless you’re a real “research hound”, readers will know when you’re trying too hard. Write about characters and subjects that you know well. Don’t be something you’re not – and don’t write where you have no experience.
Talent and Technique. Do you have the raw talent to tell a good story (whether fiction or non-fiction, it all comes down to storytelling); and do you have a firm grasp on the technique to do it properly? If you’re unclear, take a class, workshop, or read books on craft.
Book Cover. Your book will be competing against thousands of others, and if your cover doesn’t engage your reader right from the start, chances are you won’t sell many books.
Availability. Make sure your book is available for as many buying opportunities as possible. Place “Buy Now” buttons on your website or blog; link to your Amazon.com page; link to your book’s page on your publisher’s website; get neighborhood stores to carry your books on consignment; contact your local library and offer to do a reading event and provide copies to sell, with a portion of the proceeds going to the library; etc. And, make sure that you are available to make it easy for your buyers… take cash and cards!
Remember that marketing is key. People can’t buy your book if they don’t know you’ve written one. Remember to talk it up on your blog and social media. Think up a special seasonal discount promotion, contact local media outlets, offer to do guest blog appearances with reciprocal links, host a contest and give away free copies, etc.
Imagine your ideal readerand target that person. Consider writing a brief “open letter” on your blog to a specific reader explaining why you think your book might be a good fit for them. Remember to keep it fun and engaging. And, don’t forget – as wonderful as your book might be – you can’t get everyone to read it; so target those who are more likely to be your biggest fans.
Write several books. Prolific authors are profitable authors. Try different storylines with the same characters; try new genres; try fiction vs. non-fiction or children’s books. Change it up, if you like – but remember to keep it fresh. No one ever made a name for themselves or increased their revenue stream by simply “resting on their laurels”
