What makes a great domain name?
Relevant
Choose a domain that clearly connects to your business, brand, or purpose. Visitors should understand what you do from the domain name alone.
Memorable
Pick something easy to remember and spell. Avoid hyphens, numbers, and unusual spellings that make it hard to share verbally.
Short
Shorter domains are easier to type, share, and fit on business cards. Aim for 6-14 characters in the second-level domain.
On-brand
Your domain is part of your brand identity. It should feel natural alongside your business name, logo, and overall aesthetic.
