Keywords in domain no longer directly affect ranking; domain still matters for UX and brand. EMDs work when paired with quality content; branded domains with entity recognition matter more long-term.
Recommendation
:
Brand building
→ Branded or PMD; plan for months
Quick SEO traffic
→ EMD or PMD; good for tool sites, converters, generators
AI products
→ PMD (xxxGPT, xxxify) or Branded; avoid generic names that cause search confusion (e.g., multiple "Speak AI" products)
TLD Selection
TLD
Use Case
Notes
.com

Most preferred; often expensive
.ai
AI products
ccTLD (Anguilla); auto-hyperlinks in Excel/Sheets/Feishu → natural backlinks; signals AI
.io
Tech, SaaS
Popular; geopolitical risk (Chagos Islands)
.co, .app, .pro
Alternatives
If .com taken
.new
Instant-create tools
For bolt.new, claude.new style; see Alignify .new guide
AI products
Prefer
.ai
,
.com
, or
.io
. Avoid niche TLDs (.im, .xyz, .inc, .art, .dev)—higher risk of resolution issues (e.g., Notion .so outage).
Domain Best Practices
Rule
Purpose
Short & memorable
Easier to type, share, recall
Avoid hyphens
Looks unprofessional; can signal low quality
Check history
Use Archive.org; avoid previously penalized domains
Defensive registration
Register .net, .org, variants; redirect to main; do not deploy on multiple domains
Impersonation variants
For AI products: register brand+ai, brand+app, brand+official; see
brand-protection
for impersonation response
Accurate WHOIS; renew on time
Avoid loss or hijacking
.ai Domain Natural Backlinks
When brand name includes
.ai
(e.g., Character.ai, Leonardo.Ai), the full string auto-hyperlinks in Excel, Google Sheets, Feishu, and some IM apps. Each mention = potential backlink. Useful for AI products where the generic name alone (e.g., "Character") is a common noun.
