Domain names are the human-readable Internet addresses of your websites. Root domains, which are identified by their domain names and have extensions such as .com, .org, .net, etc. (Ex. http://www.example.com). Subdomains are a lower-level component of a root domain and precedes the domain name. (Ex. http://subdomain.domain.com).
Word Separators – Avoid hyphens while choosing your Domain Names. Hyphens minimizes your credibility and can act as a spam indicator.
Top-Level Domain (TLD) – Top – level domains (like .com) are the extensions associated with the domain names. For best ranking results of your domain, avoid uncommon top-level domains. Like hyphens, TLDs such as .info, .cc, .ws, and .name are spam indicators.
Length – Avoid domain names that are longer than 15 characters. Domain names less than 15 characters or that are short in length are easier to remember, easier to share and have a smaller chance of resulting in typos.
A root domain is the top level hierarchy of a domain. Root domains are purchased from registrars. The following are examples of root domains:
A subdomain is a “third level” domain name that is part of a larger, top-level domain. For example, “blog.blogspot.com” and “subdomain.example.com” are both subdomains of the “.example.com” and “.blogspot.com” root domain. Subdomains are free to create under any root domain that a webmaster controls.
The most common subdomain choices are:
- http://www.example.com (www is the subdomain)
