Whether you are a a start-up, small business or an established company, it is important to stick to these guidelines when registering your domain name.
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. https://www.example.com) Subdomains are a lower-level component of a root domain and precede the domain name.
(Ex. https://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.
