Backorders don’t take place if a domain name expires at a registrar that has an auction partner, unless no bids are placed at that auction partner prior to the expiration date. Backorders (when domains are “caught”) only happen when a domain name goes through the full lifecycle and expires, is removed from the registry’s database, and becomes available for new registration.
We do not only have Expired Domains, but you can also find lists of Deleted Domains for a lot of TLDs. Deleted Domains or Dropped Domains are available for registration and can be picked up for just the normal regfee at your preferred domain registrar! All Domains have the typical SEO relevant data, like Number of Backlinks, Archive.org Birth Date and a lot more.
