Q: What constitutes a Fail result?
A: Traffic to example.net is either blocked or redirected to a different domain. The purpose of no-www is to advocate the use of domains with optional or no www subdomain.
Q: What is Class A?
A: This is the most common no-www compliance level. With class A domains, example.net and www.example.net are both valid methods of reaching this website. Many servers default to this.
Q: What is Class B?
A: Class B is currently the optimal no-www compliance level. This classification helps remind users that, while the www subdomain is accepted, it is not necessary. In Class B, www.example.net is a valid address, but it redirects all traffic to example.net.
Q: What is Class C?
A: Class C is the most stringent compliance level. According to no-www, www.example.net is an invalid subdomain. All traffic must go to example.net in order to view the site. Very few sites currently hold this classification, partially because many internet users are not yet savvy enough to drop the www every time. For that reason, this classification is not recommended for sites that serve the general public.
Q: Why are some domains N/A?
A: The no-www standard does not apply to certain domains. In these instances, traffic to example.net may be directed to a different server or contain different content than the www. version.
Q: How can I become Class B?
A: It's a fairly simple process, actually.
Create a file called .htaccess and paste the following lines, changing the domain name to match that of your site:
