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"

For example, placing your backorder at NameJet will reveal your interest to other potential buyers so if no other backorders are present you should wait until the last possible moment before the deadline to place your backorder — because if you’re the only backorder, you’ll get it for the minimum $39 bid on expiring names and it won’t go to auction.
Once you get to this point you know there have been DMAS listed. They have a number of domains linking to them and according to the way back machine which is WBY, you can see their site age. So, if you want to go with an older site you can see right here whether or not this is a site that you might be interested in, but before pulling the trigger you do want to check two things.
Most popular auctions with expiring domains are at godaddy, namejet, snapnames. Search for expired domains name its very easy if you have domains list. With a bit luck, you can drop good one with PR5 cheaper like $200, just need to know which domain have not fake pr. List of domains are not free, but updated dailly with aprox. 50.000 new expiring domain names.
Now the numbers of errors, for we give up crawling a web site in case you know, they've got some kind of anti scraping technology or the web sites just completely knackered or something thirty is generally fine. Limit number of pages crawled per website most the time you want that ticked. I have it about a hundred thousand less you are going to be crawling some particularly big websites. I like that there, because, if you have an endless, crawl and there's some kind of weird URL structure on a website like an old-school date picker or something you don't want to be endlessly stuck on that website. Show your URLs being crawled. Now, if you just want to see what it's doing, you can have it on for debugging sometimes, but I generally leave it off because it makes it slightly faster and writes results into a text file so as it goes along and it finds expired domains as well as showing you and the GUI here, you can write them into a text file just in case there's a crash or your PC shuts down or something like that.
Since high quality expired domains are in low supply, the huge numbers of marketers competing for those drop domains tend to drive prices up. Also, if you use an exchange, you’re basically lucky to get whatever you can afford. In other words, niche specificity isn't guaranteed. This is going to be a problem because as Google continues to evolve, it is cracking down on domain niche relevance. In other words, its software is fast evolving to the point that it can tell what the niche of a particular domain is. If your private blog network is a patchwork of expired domains that involve many different and dissimilar niches, then you might be in trouble. You are at great risk of being penalized by Google.
1) pending delete auctions.  These are domains that were not renewed and are going through a pretty complicated drop process.  You can backorder these names at the auction venues and then each attempts to "catch" the dropping domain.  If one is successful you win the domain at $59 if you're the only one to backorder the name.  If more than one person backordered the domain a 3 day private auction is held.  Once the domain goes through the drop process, the back links have pretty much zero SEO benifit to the new domain owner.
What DomCop does for you, is show you a list of all these domains along with important metrics for every domain. These metrics, along with our powerful filtering and sorting capabilities, will help reduce the size of the daily list from 200,000+ to just a handful of the very best domains. What would take you hours, will now literally take you seconds to do.
