What it does
Domain Selection is an agent skill from kostja94/marketing-skills. 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.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.
When your agent uses it
- Wants to choose an SEO-friendly domain for a new site—brand vs keyword domain
- Domain best practices
- The user mentions domain choice
- SEO-friendly domain
Example prompts
- “domain choice,”
- “pick domain,”
- “SEO-friendly domain,”
- “/domain-selection”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Product type: Tool, content, e-commerce, AI product, etc.
- Brand stage: New brand vs established; solo vs team
- Goals: Quick SEO traffic vs long-term brand building
What it can do on your machine
Read from SKILL.md and the folder at commit 8dd89c5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
alignify.co
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Domain Selection loads about 1.3k tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 583 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
Reference: Alignify: Domain SEO – How to Choose SEO-Friendly Domains — detailed guide, AI brand naming, TLD recommendations, rebrand cases.
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:
- Product type: Tool, content, e-commerce, AI product, etc.
- Brand stage: New brand vs established; solo vs team
- 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.
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)
