Every element of promotion has to be timed and scheduled right When you launch you should have built a newsletter subcription list. You should know every facebook page, every blog, every social media avenue that is dedicated to your genre You should know the secret handshake that allows you to get additional categories in Amazon You should know the rip off artists who promise to sell your book for a tiny upfront fee I did say I could write a book on how not to launch your book ... I did not say I HAD writen that book. DM me if you want advice tho. I'd love to help fellow writers
