It’s easier to rank higher with expired domains: Depending upon your domain age, page authority, trust flow, expired domains tend to rank really well when compared to new domains. Most new domains don’t have any DA, page authority or trust flow so it’s really harder to rank well in Google. This won’t happen with the expired domains as they are already established well and might be getting decent amount of traffic from search engines.
A domain name that reaches expired status and is not renewed by the owner will be listed at an auction service (see FAQ for exception to this rule). The domain name does not immediately go into auction, but is immediately listed on the partnered auction service with an auction scheduled for the near future. Such a domain name will be exclusive to that specific auction service.
I want to purchase a domain name that is to expire very soon. After looking it up on Whois, the owner is revealed to be 1 and 1, which doesn’t have a designated auction house based on your chart above. How should I go about trying to buy this? Because I don’t know if it will go to auction, and if it does, which auction house I should look at. It is set to expire soon: 2015-09-21
