There are lotsa ways to flips domains. Some buy already high-price domains and add more value to them, some register new domains and try making them into a profitable site, then flip them for maybe 1 year worth of profits. If you want to do this you gotta start small, register domains yourself then build a blog that makes maybe just 5 or 10 bucks on adsense a month. If you get lucky you can actually flip these small sites (or even blogger blogs) for 150 or more.
Curious. how do you add "value" to a domain?
Just listed my website on Flippa. I need some tips to make the listing better. There are a few sellers on Flippa that get up to $2400- per sale while mine are fetching like 10% of that if I'm lucky. How do they do it?
