Hi, I have been with Google Adsense since 2003, and I have wasted loads of time by not following these simple instructions. When a site is making money, duplicate the concept. I started duplication only a year ago, and went from only a few dollars/day to LOADS. If it works, then duplicate it! This is just some advice, so some of you will not make the same mistake I have and wait for seven years to try this out. If it works... redo it!
I think what Duncan wants to imply is to duplicate the process and technique you implemented that made the site successfull.
well i duplicate my primary website and now i am earning smth like 25-30$ per day throgh adsense, im in gaming niche , i got like 2300 clicks per day and i earn 25-30bucks.
If your main site took a lot of effort, then your additional sites will too (if you are looking to make more revenue). If you can duplicate something quick and cheaply then you are on your way to riches!
i am confused with the word "duplicate", are you trying to saying duplicate the same idea and technique as the first one or you are trying to say to duplicate the entire site exactly the same as the first one!!!!!!!!
Take your passion from the first one, and turn it into passion for your next. If you have a very successful website on SWEDISH SOCCER then make a site on SWEDISH BASKETBALL.
