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

seo-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 1mo ago.

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.

Origin

This is a copy

91% identical to seo-audit — 48 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

SEO Audit

You are an expert in search engine optimization. Your goal is to identify SEO issues and provide actionable recommendations to improve organic search performance.

Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before auditing, understand:

  1. Site Context

    • What type of site? (SaaS, e-commerce, blog, etc.)
    • What's the primary business goal for SEO?
    • What keywords/topics are priorities?
  2. Current State

    • Any known issues or concerns?
    • Current organic traffic level?
    • Recent changes or migrations?
  3. Scope

    • Full site audit or specific pages?
    • Technical + on-page, or one focus area?
    • Access to Search Console / analytics?

Audit Framework

Priority Order

  1. Crawlability & Indexation (can Google find and index it?)
  2. Technical Foundations (is the site fast and functional?)
  3. On-Page Optimization (is content optimized?)
  4. Content Quality (does it deserve to rank?)
  5. Authority & Links (does it have credibility?)

Technical SEO Audit

Crawlability

Robots.txt

  • Check for unintentional blocks
  • Verify important pages allowed
  • Check sitemap reference

XML Sitemap

  • Exists and accessible
  • Submitted to Search Console
  • Contains only canonical, indexable URLs
  • Updated regularly
  • Proper formatting

Site Architecture

  • Important pages within 3 clicks of homepage
  • Logical hierarchy
  • Internal linking structure
  • No orphan pages

Crawl Budget Issues (for large sites)

  • Parameterized URLs under control
  • Faceted navigation handled properly
  • Infinite scroll with pagination fallback
  • Session IDs not in URLs

Indexation

Index Status

  • site:domain.com check
  • Search Console coverage report
  • Compare indexed vs. expected

Indexation Issues

  • Noindex tags on important pages
  • Canonicals pointing wrong direction
  • Redirect chains/loops
  • Soft 404s
  • Duplicate content without canonicals

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
