Why these skills are different

Most "SEO skills" you'll find are prompts that ask you to paste in keyword data, traffic exports, crawl reports, and backlink profiles. Then the prompt does a spreadsheet-style analysis of whatever you fed it.

These skills flip that. The agent does the data gathering itself.

• page-audit → you give a URL. The agent fetches the page, identifies the primary keyword, runs a Google search, reads the top 3 competitors, and produces a 7-dimension audit.
• content-brief → you give a keyword. The agent Googles it, reads the top 10 results, maps the intent, identifies the content gap, and produces a writer-ready brief.
• keyword-deep-dive → you give a keyword. The agent reads the SERP, classifies intent, reads the top 3 competitors in detail, and produces a 90-day ranking plan.
• write-content → you give a topic. The agent researches, asks you 2-3 questions about your expertise, and writes the article using the full anti-AI-slop ruleset.

No exports. No pasting data. No "gather this from GSC first." Just a URL or a keyword, and the skill does the work.

• page-audit — 7-dimension audit of any URL, with competitor research
• content-brief — writer-ready brief from a target keyword, with SERP gap analysis
• write-content — complete SEO article with the full anti-AI-slop ruleset
• improve-content — rewrite an existing page with better structure and voice
• keyword-deep-dive — single-keyword opportunity analysis with 90-day ranking plan
• semantic-gap-analysis — exact entities and subtopics missing from your page vs. the top 3
• eeat-audit — score Experience, Expertise, Authoritativeness, Trustworthiness with specific fixes
• topic-cluster-planning — hub-and-spoke architecture from a seed topic, with publishing order
• featured-snippet-optimizer — rewrite your answer block to win the snippet for a keyword you already rank for
• linkbuilding — phase-appropriate tactics (foundation, growth, authority) from domain reading
• expert-interview — extract first-party expertise through targeted questions, feeds into content writing

Per-skill bundled references (skills/<name>/references/)

Every skill ships with its own references/ folder containing the deeper material the skill pulls from on demand. No separate research library to install or paste — it's already bundled with each skill.

• Content-type templates (23 types total, distributed across write-content, improve-content, content-brief, eeat-audit, featured-snippet-optimizer): how-to, definition, comparison, listicle, pillar page, FAQ, landing page, service page, case study, thought leadership, product review, pricing page, about page, and more. Each includes the exact H1/H2 structure, schema markup, featured snippet strategy, word count targets, and E-E-A-T signals for that content type. A content-types-overview.md decision table covers all 23 in one place.

• Writing technique modules (in write-content, improve-content, expert-interview, and domain-specific skills): the anti-AI-slop defense system (tiered banned vocabulary, structural pattern detection, the Horoscope Test), voice injection, E-E-A-T signal embedding, information gain writing, search intent matching, topic cluster strategy, quality scoring, structured data for SERP features, and more.

• Skill-specific diagnostic references: POP test hierarchy and content-types audit summary in page-audit, CTR benchmarks and SERP volatility heuristics in keyword-deep-dive, EAV triple worked examples in semantic-gap-analysis, YMYL scoring and fastest-wins in eeat-audit, first-link-weight evidence in topic-cluster-planning, snippet format templates in featured-snippet-optimizer, and a question bank organized by content type in expert-interview.

9 link-building tactic playbooks (skills/linkbuilding/references/tactics/)

Entity stacking, citations and directories, competitor backlink gap, guest posting, resource pages, skyscraper technique, strategic partnerships, podcast guesting, and a new-site launch strategy. Each has step-by-step execution, common mistakes, and realistic conversion rates from the field. Plus three top-level safety references in skills/linkbuilding/references/: phase classification tree, anchor text safety guide, and link velocity red flags.

9 more link-building playbooks live in the InhouseSEO platform — the highest-conversion and most-underutilized tactics (link reclamation, existing relationships, testimonial building, broken link building, reactive and proactive digital PR, linkable assets, niche edits, ego bait). See the "What you get with InhouseSEO" section below.

Quick start

Each skill lives in its own folder at skills/<skill-name>/SKILL.md with a bundled references/ subfolder for heavy reference material the agent can load on demand. This is the canonical Claude Code skill-discovery layout, and it's what makes the skills work identically in Claude Code, Claude Desktop, the Claude.ai app, and Cursor — no separate paste step for content-type templates or tactic playbooks.

Claude Code (plugin marketplace — recommended)

One command installs all 11 skills at once via the plugin system:

/plugin marketplace add inhouseseo/superseo-skills
/plugin install superseo@superseo-skills

That's it. Every skill is now auto-discoverable (page-audit, content-brief, etc.) and each skill's references/ folder comes with it. Updates: /plugin marketplace update superseo-skills.

Claude Code (manual, if you prefer)

Clone the repo and copy each skill folder into your skills directory. Because the references/ live inside each skill folder, the copy brings the full ref
