I have a Twitter account with around 20 Thousand Followers. I make music and I posted a new song on iTunes priced at £1.58 to download. By Tweeting the song several times a day for around two weeks and directing Followers to the iTunes link I have already made £1,500 british pounds so $3000 dollars. Does anyone know of any other techniques for maximising Followers to iTunes Links? Ive even generated a small handful of sales from Instagram by posting pictures of my album artwork and putting the words "Pre-Order Now" as a Watermak in the pictures.
