Always make it a point to register your own domain name. Make sure you are the owner of it and all contact details are yours. Choose a domain name, which will give a good idea about our business or its core values. If you are selling herbal products a name like www.herbaldrugs.com will instantly prompt a prospective buyer who is looking for some herbal solutions.
Another good idea is to register all variants of your domain name and point them to your main domain.
For example : goooogle..com and gooogle.com both point to google.com, so if the user accidentally types in either domain name, he will be taken to the main site.
