Many authors give away free ebooks sometimes. I decided to make the first four books of the Jolie Gentil cozy mystery series free and wait to see if it made a difference.
Waiting was key. For the first few months, Smashwords reported no downloads -- keep in mind, it was free. Three months ago I saw downloads of the free book and sales of the NEXT box set began to grow on Apple. Since sales are up (I assume) my books are showing higher in Apple search results.
A book uses the same Library of Congress Preassigned Control Number in all paperback editions. I choose to use a different ISBN from my own company, but I believe BN gives them free for paperbacks. If you use a site's free ISBN, they are listed as the publisher. The author still holds the copyright, of course.
BN lets you work on covers in three pieces (front, back, spine). You can create them in Microsoft Publisher or jpg, and convert/load the front and back as pdfs. They do the spine. I like this method very much.
My Tarot cards and crystal ball have malfunctioned for months, so no predictions here. The experience does tell me it seems to pay to offer a free box set for Apple, BN, and Kobo -- via Smashwords. I publish some single books directly to those websites, but it's simply easier to do one big book via Smashwords. You only fix the epub once if there are errors.
Caveat. Free books used to increase sales a lot on Amazon. I'm not sure they do now -- at least not mine. Of course, books in KDP Select do pay some when people borrow (and read) them via this exclusive-to-Amazon marketing program.
Perhaps there are fewer free books on the other sites, so free still attracts readers. Keep in mind the book has to be a good one for readers to then buy the next books in a series. And keep writing more.
