/seo-auditor

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

/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:

# 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/
:

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:

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):

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 TypePrimary KeywordsSecondary Keywords
Homepage (docs/index.md)"Claude Code Skills", "agent plugins""Codex skills", "Gemini CLI", "OpenClaw"
Skill pagesSkill name + "Claude Code""agent skill", "Codex plugin", domain terms
Agent pagesAgent name + "AI coding agent""Claude Code", "orchestrator"
Command pagesCommand name + "slash command""Claude Code", "AI coding"
Getting started"install Claude Code skills"platform names
Domain indexDomain + "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:

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.

# 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

mkdocs build

This regenerates

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

6b. Verify sitemap

Check the generated sitemap:

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"
