seo-audit-full

seo-audit-full is a skill for Claude Code, Codex from JeffLi1993/seo-audit-skill. It costs 39 tokens per session (4,535 once invoked), scanned A, original, MIT.

A full SEO audit workflow for reviewing a web page’s search visibility and technical setup. SEO, or search engine optimisation, covers changes that help search engines understand and rank a page.

In plain words
What is it for?
Use it to audit a page URL, assess content against a target keyword, run PageSpeed checks when an API key is supplied, and review social metadata, crawl data, analytics, or competitor information when available.
Why use it?
It brings page content, speed, social metadata, and other available signals into one review. It also records which optional data sources were unavailable instead of treating missing data as a completed check.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is │ Phase 1: Run core scripts (./scripts/) │.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-full 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 12d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/check-page.py, scripts/check-pagespeed.py, scripts/check-schema.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.

How it starts

The opening of the file, as written. The whole thing — 415 lines — stays where its author put it; the contents beside it link to each section on GitHub.

seo-audit-full — Advanced Full SEO Audit

This skill runs a full single-page SEO audit from the seo-audit-full directory. It does not route to seo-audit when only a URL is provided.


When to Use This Skill

Use seo-audit-full when the user asks for:

  • "seo-audit-full"
  • "full SEO audit"
  • "advanced SEO audit"
  • "technical SEO audit"
  • "deep audit"
  • "comprehensive SEO review"
  • "audit everything"

URL-only requests are valid. When external datasets are not supplied, run the full public-signal workflow and clearly note missing data sources in the report.


Input Expected

Input Required Notes
Page URL Yes The primary page to audit
Primary keyword Recommended Improves content relevance scoring
PageSpeed API key Yes Required for full audit PageSpeed checks. Ask at the start and do not run PageSpeed without it.
Raw HTML or page content Optional Enables more accurate content checks when supplied
GSC / crawl / analytics data Optional Include when supplied, otherwise mark unavailable
Competitor benchmark data Optional Include when supplied

At the start of a full audit, ask the user for a PageSpeed Insights API key:

For PageSpeed checks, please provide a Google PageSpeed Insights API key.
Get one here: https://developers.google.com/speed/docs/insights/v5/get-started
Open "Acquiring and using an API key" → "Get a Key".
If you do not provide one, I will stop before running the full audit because
PageSpeed is a required full-audit module.

Do not run seo-audit-full PageSpeed checks without a PageSpeed API key supplied by --api-key, PAGESPEED_API_KEY, or GOOGLE_PAGESPEED_API_KEY. If the key is missing, stop and ask the user to configure it instead of rendering a full report with missing PageSpeed data.

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.
