In June I made $147.96 through the Ebay affiliate program and $16.27 from Adsense for a total of $164.23. This was with 3 BANS sites but only two of them got any real traffic. I made 4 new signups which brought in $25.00 each so you can see how important new signups are (they have to signup, bid, and then win an auction I believe for the commission to activate).
I saw a slight increase in adsense after I removed the right column and put adsense at the top of each page instead. All my sites have two columns now instead of three.
I have just bought a 4th domain and I will sell either digital cameras or digital camcorders with that one. I think I am going for the really popular “in” products right now. At this point I see BANS as being extremely important in my future of work from home jobs. If I can get each site to make $50 to $100 with minimal work, then, well, you do the math about the possibilities.
