i'm using sites such hotfile to earn some money without bothering my users with tons of advertising everywhere. I realized downloads are viable in some way... but it takes hard work to earn good money. Thing is i'm thinking about a conversion rate for each download or in general. Some uploaded files never gives any amount of downloads. Others keeps getting downloaded every day so if everybody knows something about Marketing techniques to promote, improve conversions in downloads please, let's talk about it, i would like to go deep in this subject.
