It depends how popular the domain name is and the number of links it has. Also the type of extension matters. Just tell the owner how much you are willing to part.
Maybe read some books or articles about marketing and trade negotiations.
Personally I would ask him about the price first and then if he said something to high I would tell him half of the price I’m willing to give for it and then maybe increased it a bit (but not to the top)… and give him some time to think about it if he really wants to sell the name and the offer is good enough he will be back.
Yes, see how much uniques it gets then you can divide the number of uniques by anywhere from 5 to 20 and then multiply by the price of an unique click (you can get some idea about the keyword price if you have an adwords account)
$20 is reg fee and I don’t think someone would sell anything for that price …but if the domain has no traffic at all and it’s close to the renewing time the seller may actually want to sell it for anything if there is no more buyers… but then again $20 is basically nothing I would rather let it experience and wouldn’t bother with selling it for $20.
dole.doug, unfortunately this is what people do… buy up lots of domain names and then put them up for auction to try and cash in profits from the higher price selling. You can’t do anything about it and unless your willing to pay him what he wants for it, you’ll have to get another domain instead.
Start low, see how he reacts, and take it from there
I wouldn’t know how, but seeing as the person doesn’t use the domain I’d personally assume $0. That doesn’t mean the domain has no value to him! He might have an idea for it he just didn’t have time implement yet, but already registered the domain to be sure he has it when the time comes to implement the idea. Also, he might be using it for e-mail.
That is quite low, yes, but you could try and see how he reacts. I think you won’t be able to get it for $20, but who knows.
If you don’t try you’ll never know
