Yay - This is f**cking awesome! You guessed right, this money is coming from SiteBuildIt (SBI). If I shop in the right places, this $200 is going to go a long way.
Getting this sudden burst of income also motivated me to work on my SBI site again. I added a couple of articles and did some back-linking.
I'm monetizing with affiliate marketing. That means I forward my traffic to people who sell interesting things and when they buy something, I'll get a share. This month one of my affiliates made $700 on the traffic I sent, and another made $500. This motivates me to work on my own products so that I can be the one at the end of the virtual food-chain.
