For book/ebook authors, publishers, & self-publishers
I can't seem to get sales after self-publishing on the popular amazon website as well as its subsidiary createspace. I know it takes a marketing thrust but I don't have the first clue except I know it takes alot of money to market officially. I have only one social media account and that's twitter. Tried to post there only receiving sales ion single digits. Thankful but doesn't go very far in generating much needed income.
I too struggle to get sales. The Kindle marketing tools work, but be prepared to have to pay per click-and not all of those equal sales.
Doing review exchanges helps a lot. It takes time to read and post reviews for others. Most indie authors will do this quid pro quo, though.
You can post ads for free on this site. Also, if you have ebooks available for 99 cents, Indies Unlimited allows you to post ads on their site for free every Thursday.
I have accounts on several social network sites such as twitter, linkedin, facebook and google+. They are great exposure sites. I have over 700 followers on linkedin
