I want to share a relatively easy tip with you when it comes to buying domain name. This advice goes for both aftermarket acquisitions and hand registrations, and I think it can help you get an idea of the ease (or difficulty) you may have in selling a particular domain name.
Before buying a name, do a Whois search for similar domain names, and do a search of the same keywords in different extensions. If you see that others are unregistered or owned solely by domain investors, it might be challenging to sell it to an end user buyer for whatever reason. If other similar names are owned by end user companies, you will probably have a much easier time finding a buyer.
Let me give you an example.
Let’s say you have the opportunity to purchase a large city Plumber.com domain name (let’s say LosAngelesPlumber.com) either at auction or hand registration. Do some research to see if plumbers own other large city Plumber.com domain names. In addition, see if any smaller town Plumber.com domain names are registered to local plumbers in that area. You should also check out other extensions, and do a Google search of the keyword to see what domain names local plumbers are using for their websites.
If you see the vast majority of similar domain names owned by other domain investors or unregistered, you may want to rethink buying the name. Yes, there could be some commercial value (obviously there is in my simple example), but if no plumber has bought one of the names from a domain investor, you should realize you will probably end up in the same situation.
Keep in mind this tip is one that I use when I am buying domain names to re-sell. If you plan to build out a domain name or monetize it due to known type-in traffic, this tip probably matters much less.
