Domain backorder is a service offered by ICANN-authorized companies and it is the best way to get a good domain name which was owned by some third party and was left to expire. When the registration period of a domain has ended, the latter becomes inactive, but is not erased immediately. Instead, its owner has two months to renew it. In case this does not happen, the domain name enters a deletion period which continues about 5 days and next it is deleted, so anybody will be able to register it. The backorder service allows you to make an order for such a domain name with a registrar company and they'll try to register it instantly the second it's offered. This way, you will be able to get a brief and appealing domain for your website and although these domains are registered on a first -come, first-serve basis and there is no warranty that you'll acquire the wanted domain, using an automated system gives you a significantly better chance than if you keep checking whether the domain is deleted and attempt to get it personally.
