Domain names comprising of a keyword have long since been regarded as a strong pointer when it comes to search engine ranking. This connection has been proven true over time. Nevertheless, keyword domains are still popular in the domain market. One reason for this is that keyword domains are seen by potential visitors as more relevant and are therefore taken more seriously. Catchy URLs containing strong search-volume keywords are therefore often monitored by potential customers over the years. It only makes sense to purchase an expired domain when the domain name coincides with the content, products, or services that you plan to offer with that address in the future.
Use escrow services for direct sales. When you are dealing directly with the buyer, make sure that any money that is transferred goes through an escrow service. This will ensure that all checks clear and that you aren't left with a bounced check and no domain. Escrow services may add a few days to a sale and cost you a percentage, but they can save you a lot of heartache.
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.
In the past, expired domains were used as part of black hat SEO in order to generate backlink sources quickly and easily, and this practice is still used somewhat today. Getting links in this way is not a recommendable practice. All relevant search engines work nowadays with highly complex ranking algorithms, which can no longer be outsmarted by these link networks.
Contact Potential Buying Companies: With my domain IHateCold(.com) I will email the marketing teams of some of the large winter clothing companies and let them know of the available domain to buy and a few potential slogans they could use with the domain name. This is a very “I’m here to help you” scenario that I’m curious to see how it plays out. They’ll have to learn about the domain name for sale somehow, right?
Using the keyword search feature you’d also be able to familiarize yourself with how much domains typically cost on average in a certain industry or niche. Even better, they have an addictive little app called “The Domain Game” available for iOS and Android. They basically give you a domain and you try to guess whether it sold for three, four, five or six figures. You get points for each correct answer and lose points for incorrect ones. You do this for a while and you start to see patterns. Your brain starts connecting the dots and you get better it. Now you’re ready to go out there and scout some domains!
