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"
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.

I have some pot related ones I've purchased recently that deal with the manufacturing of hemp like hempmfr.com, hempmoulding.com, hemp-textiles.com, hempecofuel.com etc.  Some of the older domains I've been sitting on are ones like internetpot.com, califunk.com, cafunk.com, caedibles.com, 1tokewonder.com, govherb.com, grasspeddlers.com, pot-megastore.com, usgov420.com etc.  Another interesting recent on I've purchased is Dogparkdates.com and dogpark-dating.com. Do any of these seem valuable in your eyes?
In today's SEO (2015) the answer would be a big no! With changes to the google algorithm and the constant updates panda, penguin, what's next...., much of the "keyword url" power is now gone. While there was a day when it made sense to buy a good named .com and expect instant indexing, not so anymore unless the site is very strong coming in ,which in that case you'll drop a minimum $50k. If you are willing to drop that kind of money and the site has a high domain authority, it might make sense as long as it matches whatever product or service that you're trying to sell. Just my opinion...
Thanks for this post. I do good with Adsense and wanted to branch out so I bought 5 domains from Namejet after reading this thread. After the 5 auctions ended I spent $500 total. I contacted 30 people about these domains and after a few bites I was able to sell one of them for $500 so I got my money back and now what I sell the other four for is all profit. The best part about this is that it is not very time consuming. I spent maybe an hour on Namejet. I spent maybe two hours sending out emails. Thanks again!
Be careful! When searching for domains, it might be tempting to, for instance, buy mcdonalds.net (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.
Aside from places where you buy and sell domain names, there are some companies around that support the business of domain flipping. GoDaddy is one of the bigger names out there that does. There, you can not only trade domain names but also park those you’ve bought. The buying, parking and selling is relatively painless and all you must give up is a small percentage of your selling price.
Hey, the possibilities are endless when it comes to domain flipping so do not think that all profitable domain names are already taken. At this time, almost 90 million .COM domains have been registered, so people tend to think that there are not many good domains left. That is not true since you still have the opportunity to incorporate two or three word target keywords.
Most domains traders, or resellers, buy hundreds of domain names. This way, the chances of hitting the jackpot are higher. But, this takes some up front money. You can start with a handful of names and work your way up. This is the best way to begin. You may also decide to purchase a name from another seller if you think that a name will be big enough.

Surely if you purchase a domain (domain1.com) and redirect it to your existing domain (domain2.com) you expect to loose all ranking for domain1.com. If 301's are used then the objective is simply to pass on authority, not dominate the search results with 2 domains. If you want to keep domain2.com in the index then you would take Rebecca's option 2 or 3.
Let’s play this out with a real example. Say you’re familiar with the real estate market in Tempe, Ariz., and you have the opportunity to purchase tempeapartments.com for $200. This might be a good deal. Tempe has a lot of rental property; it’s  a competitive market; and there’s ample turnover in the apartment space because the city is home to a major university. Ask yourself:
Thousands of domain names expire every day. The reasons are different. Some owners forgot to renew the domains, some just don't want them anymore or they moved on to other projects. For most people these so called Expired Domains don't have any value. They just see a bunch of Domain Names someone else deleted and move on, but for the people who know about SEO or the value of good Backlinks, Expired Domain Names are money just waiting to get picked up from the street. The only problem is to separate the good ones from the bad ones. That is where ExpiredDomains.net comes into play.

Hey , Nice Article . Just have one query . I read your article and the issue is I want to buy one expired domain which is too good but how can I fill the reconsideration request as the domain is banned . I have not purchased the domain yet because I want to purchase it when the domain gets unbanned . So if you check Google.com/webmasters/tools/reconsideration – Requesting reconsideration of: which is only showing the websites I have in the account .. So how can I add the domain name there . OR first of all I have to buy the domain add in GWT and then send reconsideration request . If that is so then I guess you should have mentioned in the article I suppose ? Let me know thanks
Acquiring what you believe may be a valuable domain name is the easiest part of the equation.  Finding the right  buyer is much more difficult. Using auction sites and forums is perhaps the best way to find qualified buyers that are interested in your domain, and using auctions will take some of the stress away from establishing the value of a domain name yourself.
Do you want to learn how to make money buying and flipping domain names? If so, this guide will provide you with the basic knowledge and direction required to get started! Unlike domain name investing, where a "buy and hold" strategy is the standard technique, domain name flipping is all about finding valuable domains and quickly selling them for a profit.

You can find the new fields in the Column Manager and the Majestic Filter Tab. Majestic Crawled URLs, Information about the Outbound Links of the Domain and Information about the types of Incoming Links (follow, homepage, ...). Also you can now see the detected language for the website (or previous website) on the domain and the language of the anchor text links referring to the domain. The filter for the website language only includes values with at least 20% and the filter for anchor texts only with at least 10%. When you hover over the column, you still see all values (even lower percentages), but lower values are not used for the filter. If you only want to see domains matching the majority language, use the "majority language" filter. Unfortunately that filter doesn't work in the domain name search
Dictionary Word/Pronounceable/Memorable/Brandable: A dictionary word domain name is very valuable. Of course, the more popular and widely used the word is, the better. For example, “marketing.com”, “cars.com” and “hotels.com” are 7-8 figure domain names. Even if a domain name isn’t a dictionary word, being pronounceable and/or memorable and/or brandable are all big pluses that add to its value.
