Every person that is interested in going online to purchase domain names has the dream of finding that one URL that in the future will sell for millions. While it has happened a few times for example with the smart person that saw the business.com domain name for sale and decided that it sounded like a place people would want to go. He was right because it ended up selling for around 8 million dollars a few years back. The domain name search for possible diamonds in the rough is getting smaller every day because so many people are buying domain names to park them until the time is right. I think that the best way to find a profitable domain name for sale is to purchase one that is grammatically close to a very popular website such as Google or YouTube. Just today I accidently hit the "t" key which is next to the "y" key, when trying to type in YouTube's URL and I was brought to a porn website. I can just imagine how much traffic that URL receives on typos alone. Think about things like this when on a domain name search.
