I'd like to pick the brains of all the internet marketers on here.
I've seen a lot of Viral websites come up for sale on Flippa. Like this one: https://flippa.com/4418872-one-of-a-...king-24-677-mo
The all seems to have a common pattern. They buy they traffic from a mysterious source dirt cheap and then make a profit by displaying Adsense ads on their website. They scale this system up and make a ton of money for a few months 3-5 months and then put the website for sale on Flippa.
The business model sounds great, and they have their Adsense earning verified but I am little suspicious as to why they have been so many similar websites come up for sale.
Does anyone have an idea what maybe the catch here?
