A search-engine optimisation review guide for websites in Germany and the wider German-speaking region. Search-engine optimisation means improving a site so search services can find, understand, and show it.

It is used to review site structure, page content, loading performance, redirects, language targeting, internal links, and migrations.

It helps separate observed problems from guesses and prioritise issues that may affect crawling, indexing, visibility, or local search.

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	$0.00140	$0.02585
Opus 5.5	$0.00056	$0.01034
Sonnet 5.5	$0.00028	$0.00517
Haiku 4.5	$0.00014	$0.00259

Measured 2mo ago against content hash 9f457b69f4d5, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

seo-audit 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.

Makes network callslowCapability

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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO-Audit

Diagnostiziere Crawling, Indexierung, Rendering, Leistung, Inhalte, interne Verlinkung, Internationalisierung, lokale Suche und Migrationen mit reproduzierbarer Evidenz.

Audit-Grundsätze

Bei einer URL zuerst die aktuelle Website untersuchen.
Beobachtung, Plattformbericht und Hypothese klar trennen.
Keine Rankings, Sichtbarkeit, Trafficwerte oder Erholungsfristen versprechen.
Suchmaschinenrichtlinien und Rich-Result-Voraussetzungen vor Empfehlungen in Primärquellen prüfen.
Zeichenzahl, H1-Anzahl, Klicktiefe, Keywordplatzierung und Wortzahl als Heuristiken, nicht als universelle Rankingregeln behandeln.
Zugangsdaten, private Daten, Analytics oder Search Console nur mit ausdrücklicher Berechtigung nutzen.
Audit bleibt lesend; produktive Änderungen brauchen gesonderte Freigabe.
Keine Doorway Pages, skalierten minderwertigen Orts-/Keywordvarianten, manipulativen Links oder fingierten Bewertungen empfehlen.

Kontext und Evidenz

Erfasse Website, Land, Sprache, Geschäftsmodell, Conversionziel, Umfang, wichtige Suchanfragen/Seiten, Wettbewerber, Baseline, Änderungen und verfügbare Erstanbieterdaten. Bei Einbrüchen Zeitpunkt gegen Releases, Migration, Tracking, Saisonalität, Nachfrage, manuelle Maßnahmen, Sicherheitsereignisse und dokumentierte Suchänderungen prüfen.

Evidenzreihenfolge: Search Console; Server/CDN-Logs und reproduzierbare HTTP-/Rendering-Prüfungen; validierte Analytics; Versions-/Deploymenthistorie; Crawl-Exporte; aktuelle Suchmaschinen-Dokumentation; Drittwerkzeuge ergänzend. site:-Abfragen sind kein Indexzähler.

Audit-Ablauf

1. Umfang und Baseline

Hostname-, Protokoll-, Subdomain- und Sprachvarianten bestätigen. Vorher-/Nachher-Zeiträume definieren. Nach Suchanfrage, Land, Gerät, Seitentyp, Verzeichnis und Darstellung segmentieren. Datenintegrität prüfen und je wichtigem Template repräsentative URLs wählen.

2. Crawlbarkeit und Indexierbarkeit

HTTP-Status, Redirectketten/-schleifen, Soft-404, robots.txt, Meta Robots, X-Robots-Tag, Canonicals, XML-Sitemaps, interne Auffindbarkeit, Orphans, Pagination, Facetten, Parameter und Infinite-Scroll-Fallback prüfen. Search-Console-Gründe und URL-Prüfungen stichprobenartig heranziehen. Canonicals sind Hinweise, keine Befehle; fehlende Self-Canonicals nur bei tatsächlichem Duplikationsrisiko beanstanden.

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.
