Domain backorder is a service made available by ICANN-authorized companies and it's the most efficient 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 website has ended, the latter becomes inactive, however it is not erased right away. Instead, its owner has a couple of months to renew it. If this does not happen, the domain enters a deletion period that continues about 5 days and then it gets deleted, so anybody will be able to register it. The backorder service will enable you to place an order for such a domain name with a registrar company and they'll attempt to register it immediately right after it is on the market. This way, you can easily get a short and appealing domain for your website and although these domains are registered on a first -come, first-serve basis and there isn't any warranty that you'll get the desired domain name, using a computerized system will provide you with a better chance than if you keep checking if the domain is erased and try to get it yourself.
