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.
Finally, you want to head over to domaintools.com. Then put the domain into here. What this will do is it’ll show you the history of the domain, because a lot of times these domains have been dropped like four or five times and a lot of people in SEO feel this way. I’m not sure about it. If a domain has been dropped several times, then Google does actually devalue the links pointing to that domain. So, as you can see I just changed registrars a few times and it hasn’t been dropped or else it’ll say one drops or two drops.

You can’t tell us (with a straight face) that aged dictionary word .net and .org domains won’t sell easily. The .net extension is technically OLDER than .com, and holds an equally intrinsic value to that of its .com counterpart. These LLLL .com’s that are just letters slapped together may be cute to look at and easy to sell, but in the eyes of Google, ANY aged domain that makes sense (i.e. a dictionary word) is going to be much easier to rank for than some acronym or hodgepodge .com…and at the end of the day, that holds more value than whatever society sees in these nonsensical “wqij.com” names.

Similarly, for adult items which are theme based you go for similar domain names that are suitable for such businesses. Like for bridal cakes for bachelorette we need to wish them luck sop for a bachelorette cakes and other party items site the names can be like http://www.luckonluck.com. Though somewhat it could be suitable also for book making sites. But better luck is needed to a bride after all and for HEN parties ladies need luck.
So how do you develop that instinct? NameBio maintains a database of over 500,000 historical domain sales (as of writing this post). They have interesting filtering features by which you can narrow down domains by price range, date sold, keywords and more. Simply sifting through the listings on NameBio long enough will quickly develop your domain appraisal “instinct”.
