i had a backorder for a domian that was registered at godaddy. The backorder of the domain says the domain expires feb 23, 2015. However, when i check the whois on different websites, it now says the domain is registered through feb 2016. However, GODADDY back ordering still has the domain with the expiration date of feb 23, 2015. Why would they be showing 2 different dates? The domain is not even in an auction, so the 2016 seems like the new correct date?

GoDaddy Auctions is a marketplace where GoDaddy lists domains that have expired and are in the renewal grace period. Apart from these GoDaddy also lists other domains, but the expiring auctions at GoDaddy are the most popular. Based on the percieved value of the domain, domainers and SEOs bid on these auctions. If the original owner does not renew the domain, the top bid wins the auction and gets the domain name.
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.
