After domain name finalize company register the domain in DNS without WWW and some people include the www to open but they fail then website show blank not open. So make sure you work on one side used www also and into .htaccess on apache server set www or without so visitor work on one type of domain not on two like www or not used www. http://websitename.com and http://www.websitename.com is two type of domain which open the same website .
