Based on Google Search Central, Moz, and GEO research (2025-2026). ## Sub-Commands | Command | Description | |---------|-------------| | `audit-seo` | Run full SEO audit (titles, meta, schema, speed, mobile) | | `audit-geo` | Run GEO audit (llms.txt, entity clarity, AI answer format) | | `schema` | Generate JSON-LD structured data for any page type | | `optimize` | Implement priority fixes ranked by impact | | `llms` | Generate/update llms.txt for AI crawler discovery | ## Workflow ### Step 1: Run SEO audit Check: title tags ( One-line description. ## Core pages - https://example.com/: Home - https://example.com/about: About ## Docs - https://docs.example.com/api: API reference ## Blog - https://example.com/blog/post: Title ``` Place at `/.well-known/llms.txt`. This is how AI crawlers (GPTBot, Claude, Gemini) discover your site. ### Step 6: GEO optimization | Factor | Implementation | |--------|---------------| | Citability | Publish original research, unique data. AI cites sources. | | Entity clarity | Clear about pages. Define who/what/for whom. | | Answer format | Direct answer in first 2 paragraphs before expanding. | | Conversational tone | Write naturally. AI penalizes keyword stuffing. | | Source authority | Link to .edu, .gov, peer-reviewed. Build topical authority. | | Brand mentions | Get mentioned on authoritative sites. | ## Production Checklist - [ ] Technical SEO > 90% - [ ] GEO audit passes (llms.txt, schema, entity clarity) - [ ] Core Web Vitals pass (LCP 4.0s | | INP (Interaction to Next Paint) | 500ms | | CLS (Cumulative Layout Shift) | 0.25 | Measure with: Lighthouse, PageSpeed Insights, Web Vitals extension, CrUX dashboard. ### Crawl Budget Optimization ```robots.txt User-agent: * Allow: / Disallow: /api/ Disallow: /*?* Disallow: /search Sitemap: https://example.com/sitemap.xml ``` Rules: - Block faceted navigation URLs with `?` parameters - Block internal search pages (no SEO value, consumes budget) - Keep sitemap under 50,000 URLs or split into sitemap index - Set `lastmod` accurately (Google prioritizes recently-changed URLs) - Use `` sparingly (Google largely ignores it) ### Hreflang for Multilingual Sites ```html ``` Rules: - Every language must link to every other language (bidirectional) - `x-default` for language selector page or auto-redirect - Use ISO 639-1 codes (en, es, fr, de, ja, zh) - Verify with Google Search Console International Targeting report ### Schema.org Nesting Patterns ```json { "@context": "https://schema.org", "@type": "Article", "headline": "Title", "author": { "@type": "Person", "name": "Author" }, "publisher": { "@type": "Organization", "name": "Site", "logo": { "@type": "ImageObject", "url": "logo.png" } }, "mainEntityOfPage": { "@type": "WebPage", "@id": "https://example.com/article" } } ``` Nest entities, don't flatten. Google prefers deeply-nested schema over flat arrays. ### GEO Optimization (Generative Engine) For AI search engines (ChatGPT, Gemini, Perplexity, Google AI Overviews): 1. `llms.txt` at `/.well-known/llms.txt` with structured content 2. Entity clarity: every page must answer "who, what, where, when" in first 100 words 3. Citability: include statistics with source links (AI Overviews prefer cited content) 4. Direct answers: format answers as Q&A pairs (AI extracts these verbatim) 5. Long-form depth: AI favors pages > 1,500 words with clear section headers 6. Markdown structure: AI parses `##` headers better than `` tags ## Sources - Google Search Central - Google E-E-A-T guidelines - schema.org documentation - Moz Beginner's Guide to SEO - GEO research papers (2025-2026) - Perplexity Publisher Guidelines - OpenAI GPT crawler docs ## Error Handling | Cause | Fix | |-------|-----| | Google Search Console reports crawl errors on critical pages | Check robots.txt for accidental `Disallow: /` rules. Verify server returns 200 (not 5xx or 3xx loops). Submit individual URL inspection in GSC to trigger re-crawl. | | Structured data (JSON-LD) fails Google Rich Results Test | JSON-LD must be a valid `@type` from schema.org (not a made-up type). Check required properties for the type. Use `application/ld+json` MIME type, not `text/javascript`. Escape HTML entities inside JSON strings. | | llms.txt returns 404 when accessed at `/.well-known/llms.txt` | The `.well-known` directory requires explicit server routing. For static sites, place at root: `/llms.txt` and add a redirect from `/.well-known/llms.txt`. For Next.js, add to `public/` directory. | | Core Web Vitals LCP > 4s despite image optimization | LCP element may not be an image — it could be a text block, video poster, or background image loaded via CSS. Identify the actual LCP element in PageSpeed Insights report. Preload critical resources with ``. | | AI search engines (ChatGPT, Perplexity) ignore llms.txt | llms.txt is an emerging standard (2025-2026), not universally adopted. Complement with `ai-plugin.json`, comprehensive sitemap.xml, and clear entity pages. Submit to Perplexity Publisher Program separately. | | Canonical URL points to wrong domain after migration | Stale canonicals cause duplicate content penalties. Audit all pages with a crawler (Screaming Frog, Sitebulb). Update in bulk with server-side redirects. Verify each canonical returns 200, not a redirect chain. | | Hreflang tags return 404 or self-referencing loops | Each language variant must return a valid page. Use `x-default` for the language selector page. Validate with the hreflang tag tester in GSC International Targeting report. Remove broken variant links rather than leaving dead hreflang. | | Site dropped in rankings after major redesign | URLs may have changed without 301 redirects. Audit before/after URL maps. Implement redirects for all high-traffic pages first (prioritize by organic traffic in GSC). Submit old sitemap + new sitemap to GSC simultaneously for faster re-indexing. | ## Checklist - [ ] Skill loads without errors in the AI agent - [ ] YAML frontmatter is valid (description, compatibility, audience) - [ ] Workflow section provides clear step-by-step instructions - [ ] Error handling section covers common failure modes - [ ] All referenced files (references/, scripts/, assets/) exist - [ ] Skill triggers correctly for intended use cases - [ ] No broken links or missing resources ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [EliasOulkadi](https://github.com/EliasOulkadi) - **Source:** [EliasOulkadi/shokunin](https://github.com/EliasOulkadi/shokunin) - **License:** MIT - **Homepage:** https://eliasoulkadi.github.io/shokunin/ Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-eliasoulkadi-shokunin-seo-geo - Seller: https://agentstack.voostack.com/s/eliasoulkadi - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
