I am trying to find the auction house partnered with “Registration Technologies, Inc.” (http://registrationtek.com/). They appear ancient, but still active. I have attempted to contact them and received no response to my queries. How would I go about finding the auction house they are partnered with? Are you certain that all auctioning partnerships are exclusive?
You can easily find domains using the best metrics available from Ahrefs, Moz, Majestic, SEMRush, Similar Web, SEMrush, Domain Scope and Social Networks. We buy only the best, the latest, and, the most comprehensive industry wide metrics so you have the maximum amount of information to make a decision. No other tool gives you access to 90+ metrics.
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"
Expired domains with page rank, Alexa, TF, CF, Backlinks, DA, PA, RD, etc. are of much importance. It is because search engine values those expired domains because of their pre-built matrices. It can take you months to build that trust and then it will be of the value that you want. So, what if you can find expired domains with authority links like expired domains with CNN links, expired domains with Wikipedia links, expired domains with Huffington post links, etc. This kind of expired domains will provide you some great juice for your money website.
Thousands of domain names expire every day. The reasons are different. Some owners forgot to renew the domains, some just don't want them anymore or they moved on to other projects. For most people these so called Expired Domains don't have any value. They just see a bunch of Domain Names someone else deleted and move on, but for the people who know about SEO or the value of good Backlinks, Expired Domain Names are money just waiting to get picked up from the street. The only problem is to separate the good ones from the bad ones. That is where ExpiredDomains.net comes into play.
