If you bought the domain name, the typical procedure is to unlock the domain name, then either push it to your account at the same registrar (such as https://www.domainsherpa.com/how-to-push-a-domain-name-at-godaddy-com/) or send you the authorization code so you can transfer the domain name to a different registrar (https://www.domainsherpa.com/how-to-transfer-a-domain-name-to-another-registrar/).
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.
Some people might want to skip that because they think that they've already been crawled, which is a possibility and you can apply a manual exclusion to any results you think are going to be returned on Google for your search query. So things like YouTube, you don't want to crawl, then you can add them in there and it will ignore them if they returned in the search results. Okay, so that's yeah! That's pretty much the search setting query settings here. So your search terms go here. You can have as many as you like just enter them in their line separated.
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"
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.
