Use as the umbrella skill when the user asks for a full SEO analysis or strategy." risk: unknown source: "https://github.com/AgriciDaniel/claude-seo" date_added: "2026-03-21" user-invokable: true argument-hint: "[command] [url]" --- # SEO: Universal SEO Analysis Skill Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 12 specialized sub-skills and 7 subagents (+ optional extension sub-skills like seo-dataforseo). ## When to Use - Use when the user asks for a full SEO audit or broad SEO strategy. - Use as the umbrella entry point when multiple SEO dimensions are in scope. - Use when the task spans technical SEO, content, schema, sitemaps, and AI search readiness together. ## Quick Reference | Command | What it does | |---------|-------------| | `/seo audit ` | Full website audit with parallel subagent delegation | | `/seo page ` | Deep single-page analysis | | `/seo sitemap ` | Analyze or generate XML sitemaps | | `/seo schema ` | Detect, validate, and generate Schema.org markup | | `/seo images ` | Image optimization analysis | | `/seo technical ` | Technical SEO audit (9 categories) | | `/seo content ` | E-E-A-T and content quality analysis | | `/seo geo ` | AI Overviews / Generative Engine Optimization | | `/seo plan ` | Strategic SEO planning | | `/seo programmatic [url\|plan]` | Programmatic SEO analysis and planning | | `/seo competitor-pages [url\|generate]` | Competitor comparison page generation | | `/seo hreflang [url]` | Hreflang/i18n SEO audit and generation | | `/seo dataforseo [command]` | Live SEO data via DataForSEO (extension) | | `/seo image-gen [use-case] ` | AI image generation for SEO assets (extension) | ## Orchestration Logic When the user invokes `/seo audit`, delegate to subagents in parallel: 1. Detect business type (SaaS, local, ecommerce, publisher, agency, other) 2. Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo 3. Collect results and generate unified report with SEO Health Score (0-100) 4. Create prioritized action plan (Critical -> High -> Medium -> Low) For individual commands, load the relevant sub-skill directly. ## Industry Detection Detect business type from homepage signals: - **SaaS**: pricing page, /features, /integrations, /docs, "free trial", "sign up" - **Local Service**: phone number, address, service area, "serving [city]", Google Maps embed - **E-commerce**: /products, /collections, /cart, "add to cart", product schema - **Publisher**: /blog, /articles, /topics, article schema, author pages, publication dates - **Agency**: /case-studies, /portfolio, /industries, "our work", client logos ## Quality Gates Read `references/quality-gates.md` for thin content thresholds per page type. Hard rules: - WARNING at 30+ location pages (enforce 60%+ unique content) - HARD STOP at 50+ location pages (require user justification) - Never recommend HowTo schema (deprecated Sept 2023) - FAQ schema for Google rich results: only government and healthcare sites (Aug 2023 restriction); existing FAQPage on commercial sites -> flag Info priority (not Critical), noting AI/LLM citation benefit; adding new FAQPage -> not recommended for Google benefit - All Core Web Vitals references use INP, never FID ## Reference Files Load these on-demand as needed (do NOT load all at startup): - `references/cwv-thresholds.md`: Current Core Web Vitals thresholds and measurement details - `references/schema-types.md`: All supported schema types with deprecation status - `references/eeat-framework.md`: E-E-A-T evaluation criteria (Sept 2025 QRG update) - `references/quality-gates.md`: Content length minimums, uniqueness thresholds ## Scoring Methodology ### SEO Health Score (0-100) Weighted aggregate of all categories: | Category | Weight | |----------|--------| | Technical SEO | 22% | | Content Quality | 23% | | On-Page SEO | 20% | | Schema / Structured Data | 10% | | Performance (CWV) | 10% | | AI Search Readiness | 10% | | Images | 5% | ### Priority Levels - **Critical**: Blocks indexing or causes penalties (immediate fix required) - **High**: Significantly impacts rankings (fix within 1 week) - **Medium**: Optimization opportunity (fix within 1 month) - **Low**: Nice to have (backlog) ## Sub-Skills This skill orchestrates 12 specialized sub-skills (+ 2 extensions): 1. **seo-audit** -- Full website audit with parallel delegation 2. **seo-page** -- Deep single-page analysis 3. **seo-technical** -- Technical SEO (9 categories) 4. **seo-content** -- E-E-A-T and content quality 5. **seo-schema** -- Schema markup detection and generation 6. **seo-images** -- Image optimization 7. **seo-sitemap** -- Sitemap analysis and generation 8. **seo-geo** -- AI Overviews / GEO optimization 9. **seo-plan** -- Strategic planning with templates 10. **seo-programmatic** -- Programmatic SEO analysis and planning 11. **seo-competitor-pages** -- Competitor comparison page generation 12. **seo-hreflang** -- Hreflang/i18n SEO audit and generation 13. **seo-dataforseo** -- Live SEO data via DataForSEO MCP (extension) 14. **seo-image-gen** -- AI image generation for SEO assets via Gemini (extension) ## Subagents For parallel analysis during audits: - `seo-technical` -- Crawlability, indexability, security, CWV - `seo-content` -- E-E-A-T, readability, thin content - `seo-schema` -- Detection, validation, generation - `seo-sitemap` -- Structure, coverage, quality gates - `seo-performance` -- Core Web Vitals measurement - `seo-visual` -- Screenshots, mobile testing, above-fold - `seo-geo` -- AI crawler access, llms.txt, citability, brand mention signals - `seo-dataforseo` -- Live SERP, keyword, backlink, local SEO data (extension, optional) - `seo-image-gen` -- SEO image audit and generation plan (extension, optional) ## Error Handling | Scenario | Action | |----------|--------| | Unrecognized command | List available commands from the Quick Reference table. Suggest the closest matching command. | | URL unreachable | Report the error and suggest the user verify the URL. Do not attempt to guess site content. | | Sub-skill fails during audit | Report partial results from successful sub-skills. Clearly note which sub-skill failed and why. Suggest re-running the failed sub-skill individually. | | Ambiguous business type detection | Present the top two detected types with supporting signals. Ask the user to confirm before proceeding with industry-specific recommendations. | ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing. --- Source attribution: Sansar35 Original project: https://github.com/Sansar35/claude-agent/blob/d046d088ce5a79a083f0abc0fe1b7ded73bc5b1f/claude-config/skills/antigravity/seo/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2026 Claude Agent Team contributors Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
