How can you prove your traffic stats are legitimate to a potential domain buyer? Andrew Allemann’s new DNWStats service will log into your parking stats and retrieve the data. It will then publish a certificate certifying the traffic. The service currently works with DomainSponsor, NameDrive, Parked, Sedo (but not SedoPro), and Skenzo.
DNWStats is free-of-charge. At some point the service will offer premium services, and they reserve the right to charge for the service in the future. The only down side I can see is that you enter your parking company credentials in the site. They claim not to store the information, and I certainly trust Andrew in this; but it’s always risky entering logins into other accounts.
That said, the service provided by DNWStats is an important one. This is the first cross-platform service to verify stats and provide the information (with your permission) to potential buyers. You have control over whether a certificate is private or public. Try it with a few of your domains and see how easy it is to create a certificate.
