Once you decide to sell a domain name, it is important to find the best market to sell it. The best way to sell a domain name is to approach buyers secretly. If you know someone who deals with domain names, it is recommended to contact him without going through the middleman. Chances are that the seller will make more profit, as he will not have to pay the middleman.
I did this last month, snagged a great domain that no one else found and got it for $69 because I waited until the last moment to place my pre-bid. Flipped it within a week for a little over $1,000. And probably could have gotten more if I sat back and waited 6-12 months, but a bird in the hand… (plus I like to keep turning over inventory and maintaining cash flow).
One of the easiest ways to make money online is by buying something for a low price and selling it for a higher price.  It is even better when you don’t need to pickup or ship a product.  Today I’m going to talk about how to make money online by flipping domain names and how I personally have made tens of thousands of dollars in the past year doing this.
2) prerelease auctions.  These are domains where the auction venue has contracted with the registrar, like Fabulous or Moniker, to auction off non-renewed domains.  Just before a domain enters the pending delete process, it goes to a private auction to any person who has backordered the name.  Some people feel that back links on these type of auctions still provide a SEO benifit. My testing indicates that there is zero SEO benifit when these domains are redirected into another site.  So if you get a domain with "pink squirels" in a lot of achor text to a domain and then point it at your domain, you don't rank for "pink squirels"
Selling on auction sites is another great way to find buyers. Ebay.com is perhaps, the most popular place to sell domain names. Afternic.com is another site that allows sellers to find good buyers. If you have premium domain names, become a member at GreatDomains.com and list your domain name there. The site is a reputed marketplace and brokers deal with thousands of dollars trading domain names. You can also sell domain names through Sedo.com, a site which has its own selling program. Sedo.com has the largest marketplace in the world, and boasts of having a list of the most expensive domain names in the market. It also has a safe and secure escrow service for domain name buyers and sellers.
Sellers should also learn to identify premium domain names. Dictionary names are premium domain names. Domain names with dictionary-singular names are the hottest on the Web, and buyers are willing to pay a lot to purchase them. Names, such as search.com or askme.com, will get buyers more easily than long domain names. It is also important to note that unhyphenated domain names have more value. Even product-related domain names also can enable sellers to earn substantial profit. Once a seller has a certain degree of knowledge about the domain, he can start searching for buyers.
Here's a test I have in process.  I bought an old $5 closeout domain from Godaddy TDname expired auction.  I put a quick minisite up and linked to it with a crazy anchor text phrase.  The domain is ranking for that crazy term now.  It's gone through one pagerank update and I'm waiting for a second to come.  Then I'll redirect the domain to another minisite.  I suspect the second site won't rank for the anhor text, but we'll see.  
Unfortunately, most domain names take at least a couple of months to sell, especially without an attached website. Thus, there is no need to become discouraged if your domain name does not sell immediately. Most people make the mistake of quitting their domain speculation endeavor after waiting for several months to sell without success. In reality, domain name squatting can be just as profitable, and it is a valid form of long term investing.
Check backlink profile: If you’re not familiar with what backlinks are, they’re basically any public website that “links” to the domain in question. Since there are numerous shady tactics in the SEO world, expired domains’ backlink profiles should be examined carefully. Check if too many links are coming from the same domain or if links have weird anchor texts/use foreign languages. You can use a tool such as ahrefs for these purposes.
Buying and selling Domains is a tricky industry. You easily get addicted to it without really knowing what it's all about. Unfortunately I learnt a lot of the answers on here after losing 6k on useless domains. It is a constantly changing industry but the subject that keeps coming up is TRAFFIC. Organic type in Traffic. Those premium domains are long gone and you need to spend big bucks to acquire them on secondary markets such as Domain Auctions, Expired Domain Names, and Available Aftermarket Domain Names for Sale but if you keep up to date with future trends then you can spend less on hand registered names. You really need to think outside the box and spend a lot of your time reading industry leading blogs like business insider, network as much as you can and have a specific niche before jumping into other trends that you don't quite understand. There's so many ways of selling. Don't try and sell to other people who are trading domains aka domainers instead look for an enduser on Google by typing the name you own and if there's advertisers then you have yourself some leads or use tools such as Free Domain Appraisal and Domain Productivity Tools. A buyer can be convinced to buy if you have the numbers to prove how much that domain would be worth to them. Find out how much they spend on advertising per month then make comparisons with the number of direct type in traffic they get from your domain that you selling. If you can prove these numbers then it's easier to sell otherwise you better off holding on to it, maybe develop it the way Trump has developed his name until someone interested gets in touch. There's so many platforms where you can list the domain such as The world's leading domain marketplace , Park Domains - Afternic -DomainNameSales.com etc . Please NOTE  I am not promoting any of these services but I have used them before and have had some success. Probably should have signed up for their  affiliate programs but haven't had a chance before this question came up. There's so many other metrics involved  so research as much as you can, don't spend a day without reading about the subject and go in at least knowing what you are doing. My two cents.
Choose Niches that make money: People will buy a website domain if they think they can use it to make money. So buying popular phrases/words that could be associated with selling something like computers(.com) or hotels(.com) could be used by a company to sell computers or hotel reservations. However, something like Warof1812(.com) may not have the same business potential.
Before EmpireFlippers became a website broker, the internet marketing duo Joe Magnotti and Justin Cooke had been sharing how they flip sites for cash on their widely-popular blog and podcasts. They relocated to the Philippines, hired locals to create content and build traffic, and then literally built hundreds of niche sites that earn from either AdSense ads or Amazon affiliate commissions. Every month, they chose low-earners and sold these ready-made sites on their marketplace.
Since 2013, more than 183 million domain names have been registered but none of these is used. A large chunk of these domain names is hoarded by domain flippers who will then resell these domain names to new buyers. Now if you are a newbie in this particular field, the best way to go about flipping domains is to start with a small budget until you gain relevant experience in the field.
Parking: While your domain is just sitting there waiting for its new owner, you might as well take advantage of it. Parking sets up automated advertising on your domain so that you earn money every time someone views/clicks on an ad. This could be especially useful if your domain is an expired one that’s already receiving traffic. Services that offer parking include Sedo, GoDaddy, 1and1 among many others.

Domain names have been on sale ever since the Internet revolution began during the 90s. Just because some entrepreneurs had the foresight to buy profitable domains before the rest of the world caught up with the trend, doesn’t make them domain hoarders. Domain names are just like the real estate sold in the off-line world. Anyone is free to buy/sell as many properties as one likes if his/her means permit.

If you buy a dropped domain from Snap or Namejet, the backlinks seem to be worthless for SEO.  They are valuable for traffic if it's targeted to your site.  Go ahead and 301 redirect into your site because it's the traffic from the back links that is worth something.  I use the Google URL builder to redirect these names so you can see the domain the traffic is coming from.
Here’s what you DON’T want to do: Target prospective buyers based on their perceived economic status, without any insight into the industry you’re targeting. “Lawyers seem to do well,” you think, “maybe I should start selling names to them.” So you rush out and buy a bunch of domain names you think would appeal to the law firms you’ve identified as potential buyers. Without knowledge of the space, you may not know that the American Bar Association and other industry-specific organizations set rules that govern some aspects of legal advertising. You’re not going to strike gold selling names your target buyers can’t use.
Your system is broken, You took my lising money on an open domain http://www.australianfintech.com.au and then stuffed me around something cronic and no response from your supoport team either. I have spoken to Tony who is one of the main people there at a function and I will move heaven and earth to find his number and give him a piece of my mind!! I have 60+ domains to sell but it seems you do not want the business! BAD MOVE not accomodating clients!
Buying domains or registering domains–what’s the difference? There are many ways to acquire a domain. While available domains can be registered with any domain provider, rights of use from already-registered domains have to be purchased from their current owners. You can find different market places and auction platforms online that are tailored to these purposes. This kind of domain trade is...
Expired domains are domains that have been registered by individuals, businesses, or organizations, but aren’t renewed after the contract ends, or are deliberately terminated. That means that they available for re-registration. There are many reasons why someone would choose to abandon a domain; one reason could be that the web project failed, or that a domain portfolio went into liquidization. Domains can also end up becoming free due to the owner receiving warnings for possible trademark infringement. Re-registering can also result in legal consequences.
Multiply that number by the hundreds of potential variations we got from the Google Keyword Tool and NameBio, and you’ll brain will be buzzing with ideas in not time. Of course, not all the 1,300 currencies will boom, but if you bet on the right ones and take early action, you can get your hands on some very solid domain names. You can repeat all of this for almost every industry imaginable. Use a seed keyword on Google Trends and the Google Keyword Planner then just let the data guide your journey from there like we just did.
