I am new to FSB myself, but NOT trying to make money online. I have been trying since 2001 and have tried many methods online. Some were complete failures and others simply did not earn enough to cover expenses. I understand your frustration if you start with servers, c-panel, databases, etc. But I can tell you that it's like learning to ride a bike. Once you learn it, you never forget and you can do it while you sleep. And also please believe me when I tell you that I must have tried ALL systems so far and that this one is by far the easiest to install once you master the thing.
As for the money you can earn, you look at the small picture. Remember, you do not sell anything. Your main goal is to bring people to Amazon and get them through YOUR affiliate link. You seduce them with products you hope to love, but it's not really about what's on your site. It is what they buy from Amazon, no matter what it is. You get a 4% commission on each item purchased. And you're right. 4% is not much. Not much at all. But again, look at the big picture …
You can create a site that pays $ 20.00 a day. Big deal. I know. But that's not the goal here. The goal here is to launch as many niche sites as you can muster. It only takes a maximum of 2-3 hours to create a very good site. So yes, a $ 20.00 per day winning site is nothing. But FIVE sites earning $ 20.00 a day EVERYONE is something good. TEN sites earn $ 20.00 a day and you can easily quit your job. It would be $ 200.00 a day. That's $ 6,000.00 a month or $ 72,000.00 a year!
Have the idea? Do not give up so fast. Stick to that. Remember that nothing is what you get when nothing is what you do.
