The following is the list of resources as recommended in my domain investing course.
Afternic.com – Domain selling platform I’m currently experimenting with. Owned by Godaddy, all names listed there show up in Godaddy’s search results as premium.
Godaddy.com – Home of Godaddy Auctions with the closeout section which is ripe for finding diamonds in the rough available to buy now. Also, the #1 place people search for domain names at which means massive exposure for sellers. Additionally, there auction house is a good place to list for sale, just know that anything listed in Auctions will trump Afternic prices as far as Godaddy’s search results.
NamePros.com – Best domain name forum in the world. Bad place to sell. Great place to buy.
Whois.com – Quickly look up the registrant of any domain by going to whois.com/whois/domainname.
DomainTools.com – Check if a domain has been registered before by doing to domaintools.com/domainname.
DomainIQ.com – Research prospective buyers for your inventory.
JustDropped.com – Find expired and recently dropped names quickly and you can register them for registration fee.
MergeWords.com – A great tool for combining words and/or prefixes and suffixes to come up and searching word combinations quickly.
NameBright.com – Not only one of the cheaper domain registrars but a place where you can bulk check up to 5,000 .coms at once. There isn’t a larger free bulk check available on the web.
These are all sites I have first hand experience with.
If you would like to find out how I leverage these sites to make money buying and selling domain names, my domain investor video course is $9.99 and will teach you exactly what I do.
