A good example of a website like this is a forum. Once a forum is established and up and running, it builds content itself. This increase page view which increases the likely hood of someone clicking on a link hence earning an income with something like Google Adsense. So using that realization I’ve now created a site I hope will one day will create a passive income with minimal input. Initially I considered a forum and whilst a forum is a great way to build content, you need a way to draw people to the forum in the first place. What I decided is I need a website that allows people to input content and draws people to it by it’s very nature.
There is lots of these sites out there. TinyURL and pastebin are a great example of two of these. People use these website without even considering the adds on them. They generate pages based on user content slowly earning an income. Hence the next attempt to build a passive income is http://www.somewheretowrite.com. A simple site where people can write their thoughts, feelings.. pretty much anything. As of writing there’s already been a few posts by completely random people. There’s no adds on the site at the moment. But I’ve used some specific keywords to try and target a higher link rating hence a more likely hood of people using and finding the site. I’ll give it 3 months and all going well will add adsense pages to the site.
So if your thinking about a passive income from the web, think about a site where your users are the content generators. They build the site content, hence grow the site which benefits both them and you!
