An automated review of a website's search-engine setup, content, and page code. It can also apply and check fixes such as metadata, structured data, sitemaps, social-sharing tags, and language settings.

It is for auditing and improving SEO on business, SaaS, e-commerce, and agency websites, including sites with multiple languages and regional versions.

It finds common problems that can make pages harder for search engines to understand or display. It also helps avoid checking every page and language version by hand.

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	$0.00083	$0.01480
Opus 5.5	$0.00033	$0.00592
Sonnet 5.5	$0.00017	$0.00296
Haiku 4.5	$0.00008	$0.00148

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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview

Full SEO audit pipeline: discover, audit, score, fix, validate. Detects business type from site content and tailors structured data accordingly. Handles multi-language sites with per-locale metadata and hreflang.

Required References

Before starting, read these files for lookup tables, scoring rules, code templates, and validation checklists:

references/frontend/seo-reference.md — structured data schemas, JSON-LD templates, OG locale codes, Next.js metadata patterns
references/frontend/seo-checklist.md — scoring deductions, validation checklist (40+ items), auto-fix code templates, business type mapping

Step 1: Discovery

Framework detection: Check for next.config.*, package.json (Next.js, Astro, Remix, plain React, HTML). Detect App Router vs Pages Router if Next.js.
i18n detection: Check next.config.* for i18n config or next-intl/next-i18next/@formatjs. Check for [locale] segment, messages//locales//translations/ dirs. List all detected locales.
Page inventory: Glob for page files by framework convention. For i18n sites, map each route x locale.
Existing SEO infrastructure: Grep for metadata|generateMetadata|Head|next-seo|next/head. Check for sitemap, robots.txt, manifest, existing JSON-LD, OG image generation routes.
Business type detection: Scan headings, hero text, about pages. Refer to references/frontend/seo-checklist.md for the keyword-to-business-type mapping table.

Output: Page inventory (with locale matrix if i18n), framework info, existing SEO setup, detected business type.

Step 2: Technical SEO Audit

Audit every page. For i18n sites, audit every page x locale combination.

2a: Meta Tags (per page, per locale)

<title> exists (50-60 chars), includes primary keyword, translated per locale
<meta name="description"> exists (150-160 chars), includes CTA, translated per locale
<meta name="viewport"> set correctly
<link rel="canonical"> set, points to correct locale URL
No duplicate titles/descriptions across pages within same locale
Title template uses site name suffix

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.
