I am aware of these sites:
sedo
afternic
ebay
pool
The big problem I am finding out is that domains go for $500, and have 0PR and N/A alexa. Similarly, domains going for $3000 or even $100,000 have 0PR and N/A alexa. This is disturbing. How can anyone sell a domain for that much money if it isn't even alexa ranked? I know alexa ranking isn't 100 percent accurate, but it DOES give an idea of what kind of traffic a site gets. I just dont understand how to go about buying a domain the right way I guess.
If I want to buy a domain for traffic and pagerank, where do I go? So far sedo and afternic has shown rip offs, unless I am searching their sites wrong.
and as far as alexa goes, why do you care?
Well I want backlinks and pagerank because that would be the whole purpose of spending the money to buy a domain/website. Although alexa ranking can be manipulated, an alexa ranking of "N/A" tells me the site doesn't get much traffic.
Also, why spend $500 to $1000 on a pagerank 0 site with no traffic when you can just pay $10/year for a brand new domain?
