A search-engine optimization toolkit for checking websites and improving how search engines and AI search systems understand them, using fetched data only.

Auditing sites and pages, checking structured data, images, sitemaps, international and local SEO, content quality, search intent, indexing, brand visibility, and AI search readiness.

It replaces guesswork with checks of the actual site, and reports when required data cannot be fetched.

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	$0.00044	$0.08204
Opus 5.5	$0.00018	$0.03282
Sonnet 5.5	$0.00009	$0.01641
Haiku 4.5	$0.00004	$0.00820

Security

Grade A, and why

seo scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 870 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Analyzer v4.0 — Real Data Only

BEFORE YOU START — Ask if unclear

If the user runs /seo without a URL or command, ask:

What would you like to analyze?
  1.  Full audit       — /seo audit [url]
  2.  Single page      — /seo page [url]
  3.  LLM readiness    — /seo llm [url]
  4.  Schema fix       — /seo schema [url]
  5.  Content/E-E-A-T  — /seo content [url]
  6.  Action plan      — /seo plan [url]
  7.  Brand AI check   — /seo brand [brand-name] [url]
  8.  Search intent    — /seo intent [url]
  9.  IndexNow check   — /seo indexnow [url]
  10. Content rewrite  — /seo rewrite [url]
  11. AI Overviews     — /seo aio [keyword] [url]

Which command and URL?

Never simulate, hallucinate, or estimate data you haven't fetched. If a fetch fails — say so. If you can't check something — say so.

STEP 1 — Real Data Collection (mandatory before any analysis)

When given a URL, run ALL of these in order. Never skip.

1a — Fetch live pages

WebFetch: [url]                   → parse HTML: title, meta, H1-H6, canonical,
                                    og tags, JSON-LD blocks, viewport, lang attr
WebFetch: [url]/robots.txt        → crawl rules, AI crawler allowances
WebFetch: [url]/sitemap.xml       → if 404, check robots.txt for Sitemap: line
WebFetch: [url]/llms.txt          → LLM accessibility file (note if missing)

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.
