What are Domains?
Domain names are the human-readable Internet addresses of websites. Root domains, which are identified by their domain names, have extensions such as .com, .org, .net, etc. (Ex. http://www.example.com) Subdomains are a lower-level component of a root domain and precede the domain name. (Ex. http://subdomain.domain.com)

Top Tips
- Word Separators
Avoid hyphens. Hyphens detract from credibility and can act as a spam indicator. - Top-Level Domain (TLD)
Top-level domains (like .com) are the extensions associated with domain names. For best ranking results, avoid uncommon top-level domains (TLDs). Like hyphens, TLDs such as .info, .cc, .ws, and .name are spam indicators. - Length
Avoid domain names longer than 15 characters. Short domain names are easier to remember, easier to share, and have a smaller chance of resulting in typos.
What are Domains?
Root Domains
A root domain is the top level hierarchy of a domain. Root domains are purchased from registrars. The following are examples of root domains:
- *.example.org
- *.zdemy.com
- *.blogspot.com
Subdomains
A subdomain is a “third level” domain name that is part of a larger, top-level domain. For example, “blog.example.com” and “english.example.com” are both subdomains of the “.example.com” root domain. Subdomains are free to create under any root domain that a webmaster controls.
The two most common subdomain choices are:
- http://www.example.com (www is the subdomain)
- http://example.com (has no subdomain)
