But in general, the best and easy way to sell a domain is to go with a marketplace. There is many popular marketplace dedicated to selling domains including Flippa and SellDom to sell your domain (full disclosure, I’m working on SellDom). The advantage is to leverage the popularity of that kinds of services in hope that someone will find your domain and buy/make an offer.
Official marketplaces offer a third possibility for domain traders to peddle their product. Domain marketplaces, such as Sedo, GoDaddy.com, or BuyDomains.com, connect potential buyers with domain holders hoping to sell their valuable virtual property. These platforms function as a kind of domain real estate agency and are known to sometimes demand high prices for their services.
If your domain name is related to a particular niche, then you may find success by advertising in forums that are related to that niche. Simply placing a link in the signature of your posts can tremendously speed up the selling process. While it may be possible to find prospective webmasters on niche-specific forums, it is generally better to advertise on webmaster forums, where there is a high volume of potential customers.
