Shorten links

There are numerous sites which offer link shrinking, and way to earn money is simple- copy link into link shrinking site such as AdFly, get shortened link, distribute it, and for every 10 000 views of your shortened link you get 2-5$ depending of where the views came from.

But even better is Bee4Biz:

 Bee4.biz is a link locker used to protect and shorten any url whether it's a download, video or a password while making big money in the process. Simply paste the link you want to protect, chose the category and generate a protected link like this one http://bee4.biz/v/7Mtx2 or our new transparent style locker http://bee4.biz/v/AzI-D you can share with your friends. In this case I protected a Rapidshare link to a cool Minecraft skin I've created. When somebody wants to download the skin they will be required to complete a short free survey. Once the survey is completed they will be redirected to a link you've protected and your account will be credited with some money. You get between $0.10 - $7 each time somebody unlocks one of your links, depending on the country that person is from and which survey they decide to complete. For more ideas on making money with bee4.biz and payment proof please see our forum.
Bee4.biz has some of the highest payouts you will see. Most of our competitors offer between $5 and $50 per 1000 downloads or visitors. Our average user earns 20 times more!

So - 10 cents to 7 dollars for every survey viewers decide to take.

It's up to you what you will take - 10 000 views for 5 bucks, or 1 survey for unlocking link for 7$.
