I have an idea for a website that will attract many visitors.
I will need to put a lot of effort to build it,
but then it will run (almost) by itself.
What will be the best way to convert it to some passive income?
Advertising? Affiliates? VIP registration?
How much should I expect to earn from it?
You can create your own website and apply a google adsense on it, in this way you are going to earn cash every time there is a visitor in your website or start an e-commerce website and start selling products.
this could be a good idea for him but I think it's not that simple because he needs to compete with thousands of websites in out there and he needs to be ready for this. I am sure that if he can work with focus, he can start to earn some money from the google adsense and I think the rewards are good enough for him. I think he can try to create with blogger.com or wordpress.com which is free so he doesn't need to spend any money except to pay his internet monthly fee.
