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 `{project}.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

| Type | Description | SEO | Brand | Best For | |------|-------------|-----|-------|----------| | **Branded Domain** | Domain = brand; no functional keywords (Notion, Canva, Perplexity) | Long-term; Google favors brands | High | Teams; long-term brand building | | **Partial Match (PMD)** | Part of domain relates to function (FlowGPT, Dify, Reportify) | Balance; signals topic | Medium | AI tools; balance SEO + brand | | **Exact Match (EMD)** | Domain = search query (png2jpg.com, aiartgenerator.cc) | Fast early traffic; ceiling lower | Low | Solo 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

| TLD | Use Case | Notes | |-----|----------|-------| | **.com** | Default choice; highest trust | 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.
