So, back in June, Firefox 3.0 came out, and I wanted to see if I could spin that into making some extra income via Google’s Firefox referral program, just as I had done with Firefox 2.0.

At around the same time, Yahoo! had come out with a new promotion which awarded a $100 credit for users which returned to Yahoo! Search Marketing. I figured that I should at the very minimum break even, and that an average campaign would net ~$100 US (the amount of the credit).

The Result: $184.60 in referrals. All profit.

The $100 credit from Yahoo! lasted about 6 days, so it was a really short-lived experiment. And while it is nothing close to the $2000+ I made during the Firefox 2.0 release, it’s still easy money. Easy free money. And there’s nothing better than that.

Unfortunately, a few months later, Google shut down their Referrals program, and so lost one source of passive income each month. But, I’m constantly experimenting with new affiliate programs and other sources of income, and, since then, have already overcome that loss.
