</div>


Systematically scan, audit, and optimize documentation files for SEO. Targets README.md files and docs/ pages — fixes issues in place, preserves rankings on high-performing pages, and generates a final report.

## Usage

```bash
/seo-auditor                    # Audit all docs/ and root README.md
/seo-auditor docs/skills/       # Audit a specific docs subdirectory
/seo-auditor --report-only      # Scan without making changes
```

## What It Does

Execute all 7 phases sequentially. Auto-fix non-destructive issues. Preserve existing high-ranking content. Report everything at the end.

---

## Phase 1: Discovery & Baseline

### 1a. Identify target files

Scan for documentation files that need SEO audit:

```bash
# Find all markdown files in docs/ and root README files
find docs/ -name '*.md' -type f | sort
find . -maxdepth 2 -name 'README.md' -not -path './.codex/*' -not -path './.gemini/*' | sort
```

Classify each file:
- **New/recently modified** — files changed in the last 2 commits (check via `git log`)
- **Index pages** — `index.md` files (high authority, handle with care)
- **Skill pages** — `docs/skills/**/*.md` (generated by `generate-docs.py`)
- **Static pages** — `docs/index.md`, `docs/getting-started.md`, `docs/integrations.md`, etc.
- **README files** — root and domain-level README.md

### 1b. Capture baseline

For each target file, extract current SEO state:
- `title:` frontmatter field → becomes `<title>` tag
- `description:` frontmatter field → becomes `<meta name="description">`
- First `# H1` heading
- All `## H2` and `### H3` subheadings
- Word count
- Internal link count
- External link count

Store baseline in memory for the report.

---

## Phase 2: Meta Tag Audit

For every file with YAML frontmatter, check and fix:

### Title Tag (`title:`)

**Rules:**
- Must exist and be non-empty
- Length: 50-60 characters ideal (Google truncates at ~60)
- Must contain a primary keyword
- Must NOT duplicate another page's title
- For skill pages: should follow the pattern `{Skill Name} — {Differentiator} - {site_name}`
- site_name from `mkdocs.yml` is appended automatically — don't duplicate it in the title

**Auto-fix:** If title is generic (e.g., just the skill name), enrich it with domain context using the DOMAIN_SEO_SUFFIX pattern from `scripts/generate-docs.py`.

### Meta Description (`description:`)

**Rules:**
- Must exist and be non-empty
- Length: 120-160 characters (Google truncates at ~160)
- Must contain the primary keyword naturally
- Must be unique across all pages — no two pages share the same description
- Should include a call-to-action or value proposition
- Must NOT start with "This page..." or "This document..."

**Auto-fix:** If description is missing or generic, generate one from the SKILL.md frontmatter description (if available) or from the first paragraph of content. Use the `extract_description_from_frontmatter()` function from `generate-docs.py` as reference.

### Validation Script

Run on each file that has HTML output in `site/`:

```bash
python3 marketing-skill/seo-audit/scripts/seo_checker.py --file site/{path}/index.html
```

Parse the score. Flag any page scoring below 60.

---

## Phase 3: Content Quality & Readability

For each target file, analyze and improve:

### Heading Structure

**Rules:**
- Exactly one `# H1` per page
- H2s follow H1, H3s follow H2 — no skipping levels
- Headings should contain keywords naturally (not stuffed)
- No duplicate headings on the same page

**Auto-fix:** If heading levels skip (H1 → H3), adjust to proper hierarchy.

### Readability

Run the content scorer on each file:

```bash
python3 marketing-skill/content-production/scripts/content_scorer.py {file_path}
```

Check scores for:
- **Readability** — aim for score ≥ 70
- **Structure** — aim for score ≥ 60
- **Engagement** — aim for score ≥ 50

### Content Quality Rules

- **Paragraphs:** No single paragraph longer than 5 sentences
- **Sentences:** Average sentence length 15-20 words
- **Passive voice:** Less than 15% of sentences
- **Transition words:** At least 30% of sentences use transitions
- **Bullet lists:** Use lists for 3+ items instead of comma-separated inline lists

### AI Content Detection

Run the humanizer scorer on non-generated content (README.md files, static pages):

```bash
python3 marketing-skill/content-humanizer/scripts/humanizer_scorer.py {file_path}
```

Flag pages scoring below 50 (too AI-sounding). For these pages, apply voice techniques from `marketing-skill/content-humanizer/references/voice-techniques.md`:
- Replace AI clichés ("delve into", "leverage", "it's important to note")
- Vary sentence length
- Add specific examples instead of generic statements
- Use active voice

**Important:** Only modify content that was recently created or updated. Do NOT rewrite pages that are ranking well — preserve their content.

---

## Phase 4: Keyword Optimization

### 4a. Identify target keywords per page

Based on the page's purpose and domain:

| Page Type | Primary Keywords | Secondary Keywords |
|-----------|-----------------|-------------------|
| Homepage (docs/index.md) | "Claude Code Skills", "agent plugins" | "Codex skills", "Gemini CLI", "OpenClaw" |
| Skill pages | Skill name + "Claude Code" | "agent skill", "Codex plugin", domain terms |
| Agent pages | Agent name + "AI coding agent" | "Claude Code", "orchestrator" |
| Command pages | Command name + "slash command" | "Claude Code", "AI coding" |
| Getting started | "install Claude Code skills" | platform names |
| Domain index | Domain + "skills" + "plugins" | "Claude Code", platform names |

### 4b. Keyword placement checks

For each page, verify the primary keyword appears in:
- [ ] Title tag (frontmatter `title:`)
- [ ] Meta description (frontmatter `description:`)
- [ ] H1 heading
- [ ] First paragraph (within first 100 words)
- [ ] At least one H2 subheading
- [ ] Image alt text (if images present)
- [ ] URL slug (for new pages only — never change existing URLs)

### 4c. Keyword density

- Primary keyword: 1-2% of total word count
- Secondary keywords: 0.5-1% each
- No keyword stuffing — if density exceeds 3%, reduce it

**Important:** Never change URLs of existing pages. URL changes break incoming links and destroy rankings. Only optimize content and meta tags.

---

## Phase 5: Link Audit

### 5a. Internal links

For each target file, check all markdown links `[text](url)`:

- Verify the target exists (file path resolves)
- Check for broken relative links (`../`, `./`)
- Verify anchor links (`#section-name`) point to existing headings

**Auto-fix:** Use the `rewrite_skill_internal_links()` and `rewrite_relative_links()` functions from `generate-docs.py` as reference. Rewrite broken skill-internal links to GitHub source URLs.

### 5b. Duplicate content detection

Compare meta descriptions across all pages:

```bash
grep -rh '^description:' docs/**/*.md | sort | uniq -d
```

If duplicates found, make each description unique by adding page-specific context.

Compare H1 headings across all pages — no two pages should have the same H1.

### 5c. Orphan page detection

Check if every page in `docs/` is referenced in `mkdocs.yml` nav. Pages not in nav are orphans — they won't appear in navigation and may not be indexed.

```bash
# Find doc pages not in mkdocs nav
find docs -name '*.md' -not -name 'index.md' | while read f; do
  slug=$(echo "$f" | sed 's|docs/||')
  grep -q "$slug" mkdocs.yml || echo "ORPHAN: $f"
done
```

**Auto-fix:** Add orphan pages to the correct nav section in `mkdocs.yml`.

---

## Phase 6: Sitemap & Build

### 6a. Rebuild the site

```bash
mkdocs build
```

This regenerates `site/sitemap.xml` automatically (MkDocs Material generates it during build).

### 6b. Verify sitemap

Check the generated sitemap:

```bash
python3 marketing-skill/site-architecture/scripts/sitemap_analyzer.py site/sitemap.xml
```

Verify:
- All documentation pages appear in the sitemap
- No broken/404 URLs
- URL count matches expected page count
- Depth distribution is reasonable (no pages deeper than 4 levels)

### 6c. Check for sitemap issues

- **Missing pages:** Pages in `mkdocs.yml` nav that don't appear in sitemap
- **Extra pages:** Pages in sitemap that aren't in nav (orphans)
- **Duplicate URLs:** Same page accessible via multiple URLs

## Phase 7: Report

Generate a concise report for the user:

### Pages to preserve (do NOT modify)

These pages rank well for their target keywords. Only fix critical issues (broken links, missing meta). Do NOT rewrite content:

- `docs/index.md` — homepage, ranks for "Claude Code Skills"
- `docs/getting-started.md` — installation guide
- `docs/integrations.md` — multi-tool support
- Any page the user explicitly marks as "preserve"
