First method is called the forum method. It is also insanely amazing but with this method, the more you work on it the more you will earn. The idea behind this is not to spam your link on forums and hope for downloads, that never works. People will only download your file if they want it. This technique has two sub techniques to it. The first way is to find highly populated forums and post something very related.
Here is an example: lets say we have a highly populated guitar forum. The idea is to offer a download to a file that everyone on the forum can use. Every guitarist can use some tips. Google “guitar tips e-book” and find something you like. Then upload it to sharecash and start a thread on the forum. You have to mention its free and mention that it’s a must have even for professionals. And that’s it! Watch how many people download your file! It’s insane!
The other sub technique may cost you a few bucks but is far more effective. Lets have an example: we’re still on our guitar forum and there is a user with 20,000 posts. This means his posts are basically ALL over the forum. Every user has a signature which is a set picture/text at the bottom of every of the users posts. All you have to do is offer that user for example $20/month to rent his signature space. In that signature space you will have a few of your sharecash download links with related downloads (such as the mentioned guitar tips) that will be displayed under every one of that users posts. That means that your download links are everywhere for everyone to see, click and make you money.
This is the most profitable technique but it may cost you a little to rent the signature space.
