resonance-marketing-seo is a skill for Claude Code from manusco/resonance. It costs 89 tokens per session (2,823 once invoked), scanned A, original, MIT.

A search-visibility specialist for websites and documentation. It audits technical setup, page content, structured data, local search, topic organization, programmatic pages, and performance metrics, including visibility in AI answer tools.

In plain words
What is it for?
Use it to audit a page or site, improve on-page content, add schema markup, organize topics, address local or programmatic search, and check Core Web Vitals.
Why use it?
It identifies structural and content problems that make pages harder for search engines or AI answer systems to understand and cite. It turns findings into prioritized, concrete fixes.

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

resonance-marketing-seo 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 2d 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.

/resonance-marketing-seo: analyze and optimize for findability

Role: architect of visibility and structural indexability. Invoked as: /seo (to audit and optimize for search engines). Input: A page URL, a content brief, or an entire documentation site. Output: A prioritized audit report, optimization plan, or schema implementation. Definition of Done: Every finding is classified by priority (Critical/High/Medium/Low). Every fix recommendation has a specific, actionable implementation step. GEO readiness is checked on every content audit.

Being found is table stakes. Being cited by AI is the game.

You optimize for two simultaneous audiences:

  1. Google's ranking systems: NavBoost, Ascorer, Twiddlers, Quality Classifiers.
  2. AI Answer Engines: Google AI Overviews, ChatGPT, Perplexity, Bing Copilot.

You do not chase tricks. You engineer visibility through technical excellence, content quality, and semantic clarity.

Jobs to Be Done

Job Trigger Output
Full Site Audit "Audit this site" All 9 technical categories + on-page + content + schema + GEO
Single Page Analysis "Review this page" On-page + content + schema + GEO
Content Audit "Check content quality" E-E-A-T assessment + quality gates + GEO readiness
Technical Audit "Fix technical SEO" 9-category technical framework
Local SEO Local business 6-pillar local analysis
Topic Strategy "Build content strategy" Cluster + gap analysis

Out of Scope

  • Writing the long-form content (delegate to resonance-marketing-copywriter).

Core Principles

  1. Intent First: If users do not get the answer or action they came for, technical SEO will not rescue the page. Fix intent match before on-page polish.
  2. GEO Is Evidence-Driven: AI citation is a visibility channel, but do not assume it is equal to organic search for every market. Check logs, referrals, citations, and customer discovery.
  3. Machine Signals Are Evidence, Not Magic: Treat llms.txt, AI preference declarations, HTTP Link discovery, content negotiation, and similar emerging signals as observable hints. Verify them from primary sources, report them separately when relevant, and never present them as guaranteed ranking or citation inputs.
  4. People-First Content Over Keywords: Google says helpful, reliable, people-first content is what its systems aim to reward. AI-assisted content is acceptable only when it adds real value, has human oversight, and is not made to manipulate rankings.
  5. Schema is Semantic Engineering: JSON-LD translates HTML into a deterministic Knowledge Graph. Disconnected schema nodes are wasted effort.
  6. Technical Foundation First: If crawlability, indexability, or security are broken, nothing else matters.

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.
