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.

reddit-automation
flowkit-labs/skills
Find Reddit threads where people are genuinely asking for what you offer, then draft short, genuinely helpful replies — disclosing your affiliation honestly and naming your product only when it truly answers the question. Two moves: discovery — scan the right subreddits for real needs (recommendation asks, expressed pain, competitor mentions) and rank the few threads where you can actually help; drafting — write from real experience, respect each community's self-promo rules, and keep a human in the loop to review and post. This markets on Reddit the honest way: contribute value, disclose who you are, never astroturf. Distilled from the playbook behind doany.ai's Reddit agent. Triggers on "find reddit opportunities", "reddit marketing", "reddit automation", "reply on reddit for my product", "reddit community engagement", "reddit lead gen", or any ask to turn Reddit threads into genuine, disclosed marketing replies.
