Try with a domain name or a few keywords, not a URL.
Hover has partnered with DomainAgents.com to help you acquire domain names that are owned by others, but that might be for sale.
You can open a negotiation with the current owner of the domain for $19.95. Your offer will be presented to the current owner, guaranteed.
The DomainAgents service allows you to negotiate confidentially, so the owner won't decide how much to ask based on who you are or where you work. Throughout the process, they will provide support, reengage the owner if they stop responding, and help you reach a deal however they can.
DomainAgents is a domain name brokerage and negotiation platform, offering a secure place for domain buyers and sellers to negotiate.
