What it does

SEO is an agent skill from sickn33/agentic-awesome-skills. Run a broad SEO audit across technical SEO, on-page SEO, schema, sitemaps, content quality, AI search readiness, and GEO. Use as the umbrella skill when the user asks for a full SEO analysis or strategy.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/cwv-thresholds.md`, `references/eeat-framework.md` and `references/quality-gates.md`).

It sits in Marketing & SEO, covering SEO audit, Technical SEO and On-page SEO. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • Asks for a full SEO analysis
  • Tasks that involve SEO audit
  • Tasks that involve Technical SEO

Example prompts

  • “/seo”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  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)

What it can do on your machine

Read from SKILL.md and the folder at commit ec02547. 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

    No URLs in SKILL.md.

    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

SEO loads about 1.8k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 801 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.8k

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.

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

CommandWhat it does
/seo audit <url>Full website audit with parallel subagent delegation
/seo page <url>Deep single-page analysis
/seo sitemap <url or generate>Analyze or generate XML sitemaps
/seo schema <url>Detect, validate, and generate Schema.org markup
/seo images <url>Image optimization analysis
/seo technical <url>Technical SEO audit (9 categories)
/seo content <url>E-E-A-T and content quality analysis
/seo geo <url>AI Overviews / Generative Engine Optimization
/seo plan <business-type>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] <description>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
