Keyword relevancy is not the only thing that matters when it comes to SEO. However, domain names that were previously used by other businesses usually have a lot of backlinks and a decent ranking on PageRank. Even though such domain names are usually about to expire, they are still worth a lot of money if they have a good number of backlinks and a ranking of five or more.

@ib2 @T-3D I've been a domain investor for over 10 years and have been very successful at it. There's a lot more that goes into it then just registering a domain name and hoping it will sell. You can list your domains on Godaddy auction listings or on premium listings, I've had a lot of success with those. Some good resources are,, and others.

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.

Park the domain with a domain parking service. Since you may not have content to put on the site, a parking service puts up a dummy page with ads. When people visit and click on the ads, that's money for you. This method works best with popular keyword domains that get lots of traffic. In most cases, you will not have control over what ads appear on your domains.[5]
GoDaddy offers a variety of benefits when you choose to buy or sell your domain with us. We have a unique Auction bidder verification process that protects both buyers and sellers from any kind of fraudulent activity. We also offer a handy Investor mobile app that allows you to watch auctions in real time and view their history (including number of bidders and how much they bid), all from the convenience of your smartphone.
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.
There are currently two main types of domain speculators: those that buy domains, build sites around them, and then flip the domain and accompanying website, and then there are those that buy and sell domain names without web sites attached. While both can be very lucrative businesses, the second type is much easier for novices to learn, and as such, shall be the topic of discussion for this article. 

Adding domains to our Premium Listings on our website before you sell will give them more exposure to the community. We’ll offer an appraisal for your domain to give you an estimated selling price, and you can adjust that price at any time. We also offer a comprehensive breakdown of our commission rates for all premium listings, so you can easily understand the process.

I remember the glory days of the Internet where people did make a ton of money buying domain names. Until I came across this post I actually didn't even realize that people actually still thought they could.make.a.lot of money by doing this. I have some domains that people would be interested in buying and I get contacted about them but mostly it is for people wanting to purchase them for like $1200. And for that price I would rather just hang on to the domain name. I also get contacted by a lot of people offering to sell me complimentary domain names at what I would call ridiculous premiums. The knew google is all about branding. I would consider paying for a domain name that has a great brand attached to it but I could care less about most keyword rich domain names. Of course there are always exceptions.

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.
