content-quality-audit

content-quality-audit is a skill for Claude Code, Codex from JakeLabate/Claude-SEO-Skills. It costs 115 tokens per session (1,237 once invoked), scanned A, original, MIT.

A website content review that checks how much useful text pages contain, whether pages repeat each other, and whether important headings are missing. SEO means improving a site so search engines can understand and rank it.

In plain words
What is it for?
Use it to crawl a site, measure visible word count and text-to-HTML ratio, find duplicate or near-duplicate pages, and identify pages without an H1 heading.
Why use it?
It finds pages that may offer little unique information, rely heavily on repeated templates, or contain too little text compared with their markup. These issues can make a site less useful to visitors and less likely to rank well.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

content-quality-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/audit_content.py, scripts/extract_content.py, scripts/fetch_pages.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Content Quality Audit

Audit a website's content for thinness and duplication, and produce an actionable report. These checks surface pages unlikely to rank or add value; they are signals for human review, calibrated to the site.

When to use this skill

Use this skill when the user asks to:

  • Audit or fix thin / low-value content
  • Find duplicate or near-duplicate pages (templated/boilerplate content)
  • Check content depth or text-to-HTML ratio
  • Identify doorway-style pages

Inputs to collect

  1. Site URL or URL list — a live site root to crawl (auto-seeds from /sitemap.xml), or a text file with --url-list.
  2. Scope — pages to crawl (default 500, --max-pages).
  3. Thresholds--thin-words (default 300) and --similarity (default 0.85). Calibrate to the content type before running.

Workflow

Step 1: Crawl and measure content

Use scripts/extract_content.py:

python3 scripts/extract_content.py https://example.com --max-pages 500 --output content_inventory.json
# already crawled once (e.g. in a full SEO audit)? skip the crawl and reuse the shared cache:
# python3 scripts/fetch_pages.py https://example.com --output page_cache.json
# python3 scripts/extract_content.py --from-cache page_cache.json --output content_inventory.json

For each page it records visible word count, text-to-HTML ratio, title, H1, noindex, an exact content hash, and a 32-value MinHash signature for fast near-duplicate detection.

Step 2: Run the audit checks

python3 scripts/audit_content.py content_inventory.json --thin-words 300 --similarity 0.85 --output audit_report.json

Step 3: Evaluate the audit checks

Evaluate each check in references/audit-checks.md. Core checks:

Check Severity
Thin content (below word threshold) High
Duplicate content (identical body) High
Near-duplicate content (high MinHash similarity) Medium
Low text-to-HTML ratio Medium
Missing H1 Low

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
