What you really want to do first is scroll down to where it says, referring pages for anchor phrases. All that is is the anchor text distribution to that site. As you can see here this looks like a very natural link profile. Brand name, a product that they had, no text, URL, shopping cart, wireless government. These are the keywords that were related to what that site was about. Okay?
Simple question: say I get the URL I want via auction for however umpteen hundreds of dollars, what about the renewal prices? Am I at the mercy of the auction house every year I want to renew it? Is it as simple as paying 10 or 15 bucks a year like with GoDaddy with a URL I got not through an Auction? I’m willing to pay for the desired URL up front but I don’t know what that entails down the pike.
Referring domains for anchor phrases usually reveals similar information. What you really want to look out for is whether or not the site has been picked up by a spammer in the past. A lot of times these expired domains were dropped, picked up by a website owner who then tried to rank it for keywords like Viagra, Cialis and whatever. You obviously don’t want that kind of domain.

If you buy keyword specific domains, you're really buying the type in traffic.  I use the URL builder and redirect through that URL so you can see how much traffic your getting from the keyword domain.  There seems to be no rythme or reason to what keyword domains deliver traffic and what don't.  By tracking traffic with the Google URL builder you get a feel for what names are giving you traffic and which are not. ie. the plural, the singular, two words, three words, the possessive, etc.
Ultimately, I was left with a semi-automated process of scraping sites and running an intricate series of processes to come up with a list of expired domains that I then had to evaluate by hand. This meant I had Majestic and Moz open to check the backlink anchor text and Archive.org to check for obvious spam for every single possible domain. The process was excruciatingly slow and tedious, but absolutely necessary to find domains that would be suitable for building out.
