Domain backorder is a service provided by ICANN-certified companies and it's the most effective way to obtain a good domain name that was owned by some third party and was left to expire. When the registration period of a site is over, the latter becomes inactive, but isn't removed instantly. Instead, its owner has a few months to renew it. Provided this does not happen, the domain enters a deletion period that continues about 5 days and next it is deleted, so anybody could 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 automatically as soon as it's offered. This way, you'll be able to get an easy to remember and eye-catching domain for your site and although these domains are registered on a first -come, first-serve basis and there's no warranty that you will get the wanted domain, using an automated system provides you with a lot better chance than if you keep checking whether the domain is erased and try to get it manually.
