I believe while registering domain name one should focus on
1) If domain as Company name available then it should be first Priority . For example if someone company name is Fedix India . They should try domain name as fedixindia.com
2) Other options are domain should be short , easy to spell , easy to remembered, easy to pronounce , should reflect theme of business
Now days keywords oriented domains does not matter in search Engines so try search domain which catchy and reflects true image of your business.
