While numbers like the ones seen above are impressive, most domains sell for significantly less extravagant prices and are generally in the two or three-digit range. Not long ago, those who were able to secure general terms (like icecream.com or pizza.com) not protected by trademark rights often found themselves sitting on virtual gold mines. The glory days of this boom have long since passed, and those looking for a profit in today’s market need a keen sense for coming trends.

The second option requires a bit more time and effort than a 301 redirect. You could do a mini overhaul of the site and turn it into a microsite for your main domain. This option is good for exact-match domains for your targeted keyword, and there are other reasons for going the microsite route that Rand's highlighted in his post about root domains, subdomains, subfolders and microsites. This strategy also works better if the old domain has decent rankings for the keywords you're targeting.
The first is the link profile I and actually took this example carbondsystems.com because it looked like a pretty good choice. It’s from 2003. It has some links, some age and it’s in DMAS and looked at the link profile in DMAS. So, you just copy and paste the domain,  the home page it to here, click on the search links button and this will show you all the links to that site.
METHOD 1: Find a domain name with huge potential and sell it as is – This option is tricky since many good domain names have already been bought, so your chance of being the next Mike Mann is highly unlikely. Understand that unless you have a single, generic word as domain name like these world’s highest-selling domains, it could take months or years to for your domains to sell.

When you backorder the domain it will say how long you have to place your bid in. Let’s say it says 25 days. If the domain is from one of Namejet’s partners then the auction will start in 2-3 days. If this is an expiring domain and Namejet has to catch it there is a chance they won’t catch it in which case it won’t go to auction at Namejet. If they do catch it then 2-3 days before the auction starts.
Just because something is legal does not make it ethical. While things that are legal can and often are ethical, there are practices like domain name flipping that are not ethical. Buying a domain name without intending to use it to make profit creates an unnecessary industry which costs people money and reduces general productivity and economic growth. This is the same with all practices that cost people money but do not contribute any value, most notably corruption. If we eliminated such practices our economic growth increases and general wealth is increased because our money is paying people for things that add to our lives and our communities. This does not. Evessariky reglect badly in people who choose to engage in such practices, but is a result of regulatory failure.
Domain flipping is the art of buying a good domain name at a wholesale price and successfully selling it at a resale price and making a profit. I’ve been helping clients flip domain names for over 10 years. The skills needed to be successful is some working capital, knowledge of domain valuations and a good information flow from a trustworthy domain broker who knows the landscape and can help source you the best deals.
Above you provided great information about buying and selling domain names. I have been to many blogs about the same and I have read the people make millions just by selling domain names. It's a process that one needs to learn with time and can give a good earning by reselling the domain name. The business is fruitful but one needs to read, understand the value of a domain name. Buying every domain name is a waste of money. One must see the future potential growth for that particular domain.
The domain name industry is quite similar to the real estate industry in a lot of aspects. There are end users, brokers, consultants and domain flippers or “domainers”. Domain flipping works similarly to buying a house, renovating it (or even sometimes just sitting on it) and then selling it again at a higher price point. The gist of it is: you’re purchasing a domain name and betting it’s worth (or will be worth) more than you paid for it. If you’re right, you get a nice paycheck and move on. Those who make a living out of this just rinse, repeat, and scale.
