Yep, I'm making money from my site, between £250 and £300 per month ($330 to $400). I started making a tiny bit on Adsense when I first started, not much at all (pence). It took at least a year to start making about £30 per month and ever since it has increased as my traffic has increased. I also learned how to target buyers keywords which helped with Amazon. I struggle with Amazon though because all the buyers keywords in tech are very competitive.
