You've got the story written, and now it's published in one format or another, what do you do to get the word out there to people and get some sales? My new eBook short story is out and I've done the usual things, posted on Google Plus in various communities, on Facebook on every book group I can find and sent to friends to see about getting the word out to all their friends I've received one good review on Amazon but so far I haven't gotten much sales traction. What other types of marketing has worked for you to get some sales? Any other tips you can give a new Indie Author trying to navigate this competitive market?
