Domains that are indexed on Google and highly ranked are particularly attractive to traders. Other SEO aspects, such as backlink profiles or the search volume of the keywords in domain names, also play a significant role in calculating thevalue. Design can also positively affect the price of a domain. Short and succinct names that are easy to remember are especially advantageous. Endings are further factors that should be taken into account. Top-level domains (TLDs) such as .com or .org are by far the most sought-after endings.
You can’t tell us (with a straight face) that aged dictionary word .net and .org domains won’t sell easily. The .net extension is technically OLDER than .com, and holds an equally intrinsic value to that of its .com counterpart. These LLLL .com’s that are just letters slapped together may be cute to look at and easy to sell, but in the eyes of Google, ANY aged domain that makes sense (i.e. a dictionary word) is going to be much easier to rank for than some acronym or hodgepodge .com…and at the end of the day, that holds more value than whatever society sees in these nonsensical “” names.
In order to maintain ownership of a domain, you must renew it yearly. If you don’t, it “expires”. An expired domain goes through several stages before being released again for general registration. The process differs slightly from one registrar to another but it’s more or less the same. GoDaddy explains what happens to domains that expire with them here.

The truth is that you require at least one year’s time to get around only the basics of the domain flipping business, leave alone making huge money from it. During this time, you’ll make several mistakes, buy useless domain names, lose out prospective deals and much more. Domain flipping is far from any get rich quick method. If overnight results are what you’re after, domain investing may not be your piece of cake. This business involves a real and steep learning curve which many people find difficult to climb.

Just because someone spent five or six figure amount on a domain name doesn’t automatically imply that he/she’ll spend the same or at least a few thousand dollars on a similar name too. Basing your domain flipping strategy entirely on what others have just bought may not be as useful as you may think. Every domain name has a story behind it and its purchase/sale is usually as unique as that story.
Yes, buying existing domain names can be profitable too. Existing domains with a potential for profit can be found using Sedo. Make sure you pick domain names that have good traffic, backlinks and Google PageRank under 17 characters. Also, steer clear of existing domain names containing special characters or numbers because they are not likely to be sold.
Granted, it is not bad information, however, if EVERYONE rushes to namejet and signs up, the only people that really benefit are namejet 😉 The increase in competition means there are more bidders in the pool which will likely increase bid amounts (because the newcomers will not be able to ascertain a “true value” as much as a “pro” flipper would). The result is a lower profit margin as the method becomes saturated.
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.
Another point of concern is that many people feel that squatting or registering domains is unethical. This is because many web developers have a hard time finding relevant domain names for their projects since most of them have already been registered. Many corporate giants also frown upon the domain flipping industry because many domain names relevant to them are already registered.
Also,, makes millions a week selling domains,even in the past week[3]! If you want to sell here, I would probably use a paid category or featured listings, one of my category listings, got 44 views in just 1 week but still waiting for a sale this month, hopefully. I would not really on this as a business, unless you add web development to it, and also, be sure to check that you are making a good profit, say within 6 months!
The easiest and least time consuming option is to 301 redirect the old domain to your existing site. This tactic obviously works best if both sites are in the same sector and are targeting the same keywords; otherwise, if you have a pet supply site and you buy an old Texas Hold 'Em poker site, a redirect probably might raise some eyebrows among the search engines. If, however, your site is and you buy and 301 redirect the domain over, you're inheriting a lot of topical and appropriate links.

I have an interesting twist on how I have done it in the past. I will buy a domain and use it as a development domain for blog posts and things of that nature. Then over time it will gain DA and PR. Then I will sell it off and buy another development domain and start the process over. Not quite the process you mentioned, but it works. People will link to the development site to show things off as well  sometimes, so that helps.
Most popular auctions with expiring domains are at godaddy, namejet, snapnames. Search for expired domains name its very easy if you have domains list. With a bit luck, you can drop good one with PR5 cheaper like $200, just need to know which domain have not fake pr. List of domains are not free, but updated dailly with aprox. 50.000 new expiring domain names.
Your domain name registrar may provide you with a free one-page Website tool, which you can use to create a “this domain is for sale” landing page. Alternatively, you can create a single page (perhaps a hidden page hanging off one of your existing websites) that indicates that your domain names are for sale. You can then forward all of your domain names that are for sale to that one page.
I've fixed some speed related problems and the new search cluster is now live. The combination of both speeds up every search noticeably. Also some unfinished expired lists are no longer in the domain name search. Some users noticed that you could already find TLDs in the domain name search that were not released yet. This is not possible anymore, however if you are one of those users, contact me. Let me know what TLD you are interested in and I will prioritize it.
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.
To sell a domain name, one should learn to price it. Many sellers fail to sell names in the marketplace, simply because they overpriced the domain, and thereby lost the chance to sell it. A lack of knowledge leads to erratic pricing. Experienced buyers will not try to bargain, unless you have a very rare name. A seller should therefore, understand how good the domain name is. What price will he get from a buyer? What suffix does it carry? For instance, .com names are likely to sell fast and will bring greater profits than, say .info names. Similarly, .net, .org and .in domain names are the best to make decent profit.

Don’t get me wrong, I’m not saying marketing your domain is not important. But, if you’ve bought a bad domain and you do (and overdo) everything laid out in this section and more, it’s still very unlikely that it would sell. It’s like spending car flipping and spending a huge amount of money, time and effort perfecting a car’s paint job, except that this car’s engine is completely fried. You’ll never be able to drive it anyway, no matter how awesome the paint job is, it’s irrelevant.

Good point. Is the amount of work that went into getting a successful sale worth a $400 profit? Keep in mind, this is providing speculative numbers for the sake of debate. The real world hours invested in gaining position or page rank, and time a agency would sit on a domain before a sale would be much higher. We interviewed a few agencies that practiced this, not only those that supported our theory.
Be careful! When searching for domains, it might be tempting to, for instance, buy (if it were available) and then try to sell it to McDonald's. The logic here would be that they own the .com and wouldn’t want anyone to own the .net and use their name, right? Also, it’s a big name so there’s gotta be a biiiiiiig payday comin’, RIGHT? Wrong, and wrong.
