For October, I decided to make two of my novels go free on Amazon(only in the US) just to see what would happen, by making them free on Smashwords, which made them free on Sony, Apple, Kobo, etc. I also had them distributed to B&N, but I don’t have any sale/download figures for anything yet except for Amazon, Smashwords itself, and my novels that I’ve published through Pubit on B&N.
8139 novels downloaded for free (giving me a little over 10k books bought or downloaded this year, and 11,100 total all time). That’s astounding to me, and I really would’ve preferred those to have been at regular prices (almost a year’s salary! lol), but I just thought I’d try to see what would happen. While sales continued for Shattered Earth, I don’t think it helped the sales of any of my other novels, and I don’t think I’m going to do free again, unless its giveaways or coupons on Smashwords.
