I emailed Katie Klein asking her about her eBook sales success, and how she had initially gotten the word out. She very kindly replied! Thank you, Katie.
Katie shares: “The truth is, I didn’t do any major advertising/promotion when I released my books. I released them quietly in the middle of the night. :)”
This was not the response I expected… but seems to be perhaps an encouraging sign. Maybe there is an element of “if you build it, they will come” in this business.
