I started
SatoshiReserve a little over a week ago after experimenting with a microwallet faucet I was running on my faucet rotator. I really liked the system, and had seen the potential to make a profit was there, but it would take further experimentation. So I took the revenue from an ad sale on the rotator and deposited that to my microwallet api account.
What I would recommend for anyone considering opening a faucet is find a decent host, you'll need a mysql database and ftp access to manage the site. Stay away from hostgator or godaddy. I have been using midphase for a couple years without problems. My site runs on shared hosting without any major speed issues. Though I have trimmed down some of the code of the faucet. If you can modify php and have even minimal experience with mysql this is doable.
As far as marketing, I have been telling everyone in bitcoin I know about the site, posted in this forum and a few others. Thankfully a few sites have picked it up, as well as several rotators. Traffic is picking up every day. Average page views per day have been about 300 a day, but for a site that's a week old it doesn't seem too bad to me. Bounce rates are pretty good.
I haven't been maintaining daily profit & loss accurately, just an overall spreadsheet the last week. So I'll start from a baseline today, and start tracking all of it.
The faucets starting balance was 0.10189309, currently it sits at 0.1014985. So over the last week, we've paid out 39,459 satoshi. Overall revenue we've taken in 0.00115973 through a-ads, adsense I can't disclose but let's say it's significant. I switched the site to solvemedia yesterday with about $0.08 in revenue. Might switch that back to reCaptcha after some feedback of a couple users. Overall profit for the week in bitcoin revenue only is 0.00076688. Is it making a profit? Yes only because the hosting is paid for by other projects. Will it maintain this level or grow, or will it go belly up? We'll see.
