Many non-savvy internet users may not even be aware of the existence of other extensions. That said, because there are many new extensions popping up every now and then, you can often find amazing one word and 3-letter domain names with these new extensions that are otherwise almost impossible to find unregistered in the .com world. Additionally, these new extensions are becoming more and more familiar to users every day, hence it's almost certain that their value will continue to increase as time passes and wider adoption manifests.
If you are feeling ambitious, you can link each of your domain names to its matching “buy it now” purchase page at one of the marketplaces. Another more sophisticated option would be to “park” your domain with one of the leading domain parking companies, such as DomainSponsor or SmartName and enable their built-in “for sale” message and contact mechanisms.
Unfortunately, you probably won't like my tips. You need to look for quality domains at a good price and be willing to hold on to them to get your money back or know when you've invested wrong and get rid of them. Quality is in the eye of the holder, and believe me, I've looked at plenty of domain portfolios that the owner just knew were million dollar domains but in my opinion, they'd be hard pressed to get anyone to take them off their hands for just the registration costs. You have to figure that most of the best .com domains were registered in the 90's, and those are the ones you typically see the 6-7+ figure sale prices on. I'm not saying there isn't money to be made because there is. But it does take time, research and money, and maybe in some cases a little bit of luck. If you're thinking of getting into the industry, I recommend digging into the resources provided by Michael Cyger on http://domainsherpa.com and from there, moving to some of the other big blogs such as TheDomains.com or
The "Domain Lists" and the "TLDs" filter are now static and not created dynamic based on the current search. Turns out creating these 2 filters dynamically was slowing down the search tremendously. It even made certain requests impossible. For example now you can do a dot search that affects all .com domains and get a result with over 150mio domains in reasonable time. I'm also working on a new search cluster that will make searching even faster (not released yet).
Think of ways that the domains you buy would be a valuable asset to the buyer. Picture someone who would benefit from buying the domain in a space you are very familiar with. If this was you and someone was trying to sell you this name, would it be beneficial for you to own? Be honest. If so, why? If not, why? Use those answers to refine your search for names.
Buying and selling domain names is an exciting adventure that for some seems to conjure up images of finding hidden pirate treasure or guessing the winning combination on the next Powerball. Stories abound of domains that were purchased for $8 dollars 15 years ago being sold today for millions. Of course, that leads the more adventurous of us to wonder, “How can I do that?”
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.
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"
Length: This is pretty self-explanatory. Generally the shorter the domain name, the more valuable it is. This difference in value decreases exponentially as the name gets longer, though. For instance, the difference in price between 3 and 4 letter domains are significant, while the price difference between a 7 and 8 letter domain would usually be much less significant.
