Domain backorder is a service offered by ICANN-authorized service providers and it's the most effective way to acquire a good domain name which was owned by some third party and was left to expire. When the registration period of a domain has expired, the aforementioned becomes inactive, but is not erased right away. Instead, the owner has 2 months to renew it. Provided this doesn't happen, the domain name enters a deletion period which lasts about five days and following that it is deleted, so everyone could register it. The backorder service allows you to place an order for such a domain name with a registrar company and they'll try to register it instantly once it's on the market. Thus, you will be able to get a brief and appealing domain name for your site and although these domains are registered on a first -come, first-serve basis and there is no guarantee that you'll get the wanted domain name, using an automated system will give you a significantly better chance than if you keep checking whether the domain is erased and try to obtain it yourself.
