Best practises for selecting a Domain Name.
Domain Names should possibly be short and easy to remember.
Domain Names should reflect your whole idea of going internet. That is its hould be a close match for the product / services / company / organisation / idea for which you are chosing the internet/web market.
TLDs should also be apt for your domain names.
ccTLDs are helpful if you wish to target geo-located audience.
Do not forget to renew your domain names before expiry to avoid loss of domain and to avoid late fee charges.
