A good research is required for selecting your domain name. First of all see your needs. If you are building a website for your business, then a domain name related to your company name or products may be better for you. Customers can easily understand and relate your services with your domain name.
If you are making a website for your professional career, then a domain name related to your name or career field may be better. Now when you are done with your wish list, you should check the availability of the domain name. Unfortunately, some registrars are in the habit of automatically registering a quality available domain when someone searches for it through their “Who is” (Whois is the record of the registration of a domain name). Therefore, it is recommended that you use one of the free who is look up services located at Whois.sc or Whois.net
If your domain is available, by all means, go ahead and register it. Many registrars will try to sell you additional services at the time of checkout. Choose these services very carefully as many happen to be redundant. One add-on service you can benefit from is Whois protection/privacy. This service basically hides your name, address, and phone number on any domain that you own, thereby ensuring your privacy. Once you’ve selected your services, simply pay using a credit/debit card or PayPal and wait for the domain to appear in your control panel. From there, you can configure its name servers, contact details, registrant, etc.
