Short answer: Choose a domain that's short, memorable, easy to spell, and represents your brand. Aim for .com if possible, avoid hyphens and numbers, and make sure it's not trademarked.
Imagine explaining your domain on the radio. If someone hears it once, can they spell it correctly and find your site? If not, simplify.
Before registering, search the USPTO trademark database. Using a trademarked name can lead to legal battles and forced domain transfers. Not worth the risk.
Good: acmecoffee.com, quickbooks.com, stripe.com
Avoid: best-cheap-coffee-shop-2026.com, kwik-bks4u.com
