eNom has joined a number of domain backordering services that now highlight high quality expiring domains.
When users of eNom’s Club Drop system login, they can now view a list of “Premium Domains” as designated by eNom. eNom uses “proprietary tools” to discover which domains have high value. This likely means they check backlinks, Alexa rank, etc. eNom is not the first backorder service to do this. GoDaddy currently has a category of “high value” expiring domains. Because these domains are all registered at GoDaddy, GoDaddy is able to count actual traffic and click-throughs on the domain. SnapNames also has a feature that highlights valuable domains.
Savvy domain investors use a variety of tools (such as SnapCheck) to find good expiring domains. If additional backordering services start identifying these good domains to the general public, you can expect the auction price for these domains to increase.
