A set of instructions for checking a website's search-engine readiness, including whether pages can be found, work correctly, and contain useful optimized content. SEO means improving a site so search engines can understand and rank it.

Reviewing crawlability, indexing, speed, page metadata, content quality, links, search priorities, and known ranking problems.

It gives an audit a defined order and scope, helping separate technical problems from content and authority issues.

seo-audit — Skill for Claude Code by seite-sh

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add seite-sh/seite --skill seo-audit

git clone --depth 1 https://github.com/seite-sh/seite

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.02075
Opus 5	$0.00044	$0.01038
Sonnet 5	$0.00017	$0.00415
Haiku 4.5	$0.00009	$0.00208

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 9d 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

100% identical to seo-audit — 0 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:

Site Context
- What type of site? (SaaS, e-commerce, blog, etc.)
- What's the primary business goal for SEO?
- What keywords/topics are priorities?
Current State
- Any known issues or concerns?
- Current organic traffic level?
- Recent changes or migrations?
Scope
- Full site audit or specific pages?
- Technical + on-page, or one focus area?
- Access to Search Console / analytics?

Audit Framework

Priority Order

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

Technical SEO Audit

Crawlability

Robots.txt

Check for unintentional blocks

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 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.
