Domain forums are excellent resources to learn about the domain market and keep up to date with the latest domain name news. They are also an option if you want to liquidize your domain portfolio quickly. The main drawback of selling your domains on forums such as NamePros or DNForum is that you will likely only receive a fraction of the price that you could reasonably expect an end user to pay. The reason for this is simple, domain forums are populated by domain resellers, and thus they buy with the intention to resell and make a profit.
Typically, it is new domainers who sell exclusively via domain forums. This is understandable at first glance, as it’s quick, easy and initially fun. There comes a point in a domainer’s learning curve that he or she realizes they are leaving a big amount of money on the table using this method. First hand experience of this occured when I purchased a domain for $120 and sold it within 2 weeks for $700, only to find a more experienced domainer sell it on to an end user for $2,500 a week later.
The underlying message is this – if you plan to sell, research potential end users and sell on domain forums as the last option.
