It's not faucet sites, but maybe you can add task sites, where you can earn bitcoins for doing small tasks. You could then add these links with you're referral link and make a percentage of what they make. I have been using these sites for about 6 months and have earned a few hundred dollars in btc. I posted this back in August:
"I'm pretty much a newbie, I got into Bitcoins around May 2013. I wondered how I can get some. So I started visiting all the faucets getting around 500 micro Bitcoins a day. I did that for a while and figured there had to be better way. So I did some searching on the web for ways to make Bitcoins. I came across several sites where you can do small tasks and offers for bitcoin. Some of the offers involve downloading software to your pc, I would stay away from those, may have virus or something. In my 4 months of "working" I've found out that doing the Crowdflower Tasks are the best and easiest way to earn. Here are the sites with comments:
Tasks4dollars -
http://tasks4dollars.com/I think this is the best one out there. It gives you better pay for the tasks than the others. Stick to the Crowdflower tasks. They also run a monthly task contest.
Dollarrewardz -
http://dollarrewardz.com/Run by the same guy who runs T4D. Same pay for tasks as T4D but has different tasks. I think this site may be geared more towards Europe. Also has offers. The offers don't always convert, meaning you don't always get paid. And it's not the guy's fault that runs the site if you don't get paid. So do them at your own risk. Stick with the Crowdflower tasks, the others don't always convert (Super Rewards, Winter Wall, Supersonic Ads, etc). I wasted a lot of time doing offers and not getting paid. Again, it's not the Dollarrewardz site's fault, they only get paid when you do. Stick to Crowdflower, they always pay.
Bitcoinget.com and coinworker.com are two others, but they pay you less for doing the same tasks."
hope this helps, maybe you can earn some btc.
anyways feel free to earn Bitcoins without the mining part too.
