The results can be different on a daily basis because more and more domain names expire on a regular basis, and some of them are worth real money. All that they have to do is to key in particular keywords that clients regularly search for in their niche and appear on the first page of most search engine results. You can get more that a dozen of expired domain names daily using this fantastic tool.
2) prerelease auctions.  These are domains where the auction venue has contracted with the registrar, like Fabulous or Moniker, to auction off non-renewed domains.  Just before a domain enters the pending delete process, it goes to a private auction to any person who has backordered the name.  Some people feel that back links on these type of auctions still provide a SEO benifit. My testing indicates that there is zero SEO benifit when these domains are redirected into another site.  So if you get a domain with "pink squirels" in a lot of achor text to a domain and then point it at your domain, you don't rank for "pink squirels"
This is not the case at GoDaddy Auctions, however. There, GoDaddy starts the auction before the domain names has fully expired and the registrant does have the ability to pay a one-time restoration fee to restore ownership. This is particularly frustrating to those bidding in the auction, as you may be the winning bidder and pay your winning bid price only to find out a few days later that it was restored. You then have to wait for a refund from GoDaddy.
Page authority ranking criteria are similar to domain authority. It’s ranked on a scale of 1 to 100. Page Authority measures the predictive ranking of a web page. The page authority of a website can change depending on various metrics. Search engines examine the relevance and authority of a page based on its contents and external links. If a webpage has links to higher authority sites and has keywords in it, its authority ranking will increase.
The way this list is implemented means I can't update prices, nor removed sold domains automatically and sedo doesn't provide me with the tools I need to implement it properly. Unfortunately some users keep contacting me to update their domain prices or remove their domains and I can't keep doing that manually. So I've decided to disable the list for now.
