When the user wants to choose an SEO-friendly domain for a new site—brand vs keyword domain, TLD selection, or domain best practices. Also use when the user mentions "domain choice," "pick domain," "SEO-friendly domain," "brand domain," "EMD," "PMD," "exact match domain," "partial match domain," "TLD," ".ai domain," ".com vs .io," "domain length," "domain history," or "defensive domain registration." For migration, use rebranding-strategy.

AI-generated overview

Guides choosing an SEO-friendly domain: brand vs keyword type, TLD, length, history and defensive registration.

What it does
This skill provides guidance for picking a domain for a new site. It compares branded, partial-match and exact-match domains, recommends TLDs such as .com, .ai and .io, and lists best practices covering length, readability, history checks and defensive registration. It produces a domain-type recommendation, a TLD recommendation, a checklist and suggested next steps.
When to use it
Use it when a user is choosing a domain for a new site, weighing brand versus keyword domains, or deciding on a TLD. It also applies to questions about domain length, domain history or defensive registration. For changing an existing domain, the skill points to a separate rebranding skill.
Requirements
No scripts or special tooling; it is instructions only. It optionally reads a root contextus.md project file when present and otherwise relies on user-provided project facts.

Strategy: Domain Selection

Guides initial domain choice for a single site: Brand vs Partial Match vs Exact Match domains, TLD selection (.ai, .com, .io), length, readability, history check, and defensive registration. A good domain affects SEO, brand perception, and UX. See domain-architecture when planning for multiple products; rebranding-strategy when changing domain.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.

Identify:

  1. Product type: Tool, content, e-commerce, AI product, etc.
  2. Brand stage: New brand vs established; solo vs team
  3. Goals: Quick SEO traffic vs long-term brand building

Domain Type: Brand vs PMD vs EMD

TypeDescriptionSEOBrandBest For
Branded DomainDomain = brand; no functional keywords (Notion, Canva, Perplexity)Long-term; Google favors brandsHighTeams; long-term brand building
Partial Match (PMD)Part of domain relates to function (FlowGPT, Dify, Reportify)Balance; signals topicMediumAI tools; balance SEO + brand
Exact Match (EMD)Domain = search query (png2jpg.com, aiartgenerator.cc)Fast early traffic; ceiling lowerLowSolo devs; tool sites; site networks

Google stance: 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

TLDUse CaseNotes
.comDefault choice; highest trustMost preferred; often expensive
.aiAI productsccTLD (Anguilla); auto-hyperlinks in Excel/Sheets/Feishu → natural backlinks; signals AI
.ioTech, SaaSPopular; geopolitical risk (Chagos Islands)
.co, .app, .proAlternativesIf .com taken
.newInstant-create toolsFor 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

RulePurpose
Short & memorableEasier to type, share, recall
Avoid hyphensLooks unprofessional; can signal low quality
Check historyUse Archive.org; avoid previously penalized domains
Defensive registrationRegister .net, .org, variants; redirect to main; do not deploy on multiple domains
Impersonation variantsFor AI products: register brand+ai, brand+app, brand+official; see brand-protection for impersonation response
Accurate WHOIS; renew on timeAvoid 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.

Output Format

  • Domain type recommendation (Brand / PMD / EMD) with rationale
  • TLD recommendation
  • Checklist (length, readability, history, defensive registration)
  • Related next steps (website-structure, rebranding-strategy)
