Technical SEO

Technical SEO

Script location. If your host does not set ${CLAUDE_PLUGIN_ROOT}, the scripts are in this plugin's scripts/ folder, next to skills/. Run them with Python 3.10 or newer: python, or python3 where python is not found (macOS, many Linux systems).

When to Use This Skill

Activate this module when the user's request involves any of the following:

• Core Web Vitals: Optimizing LCP, INP, or CLS scores; diagnosing page speed issues; interpreting CrUX data or PageSpeed Insights reports
• Crawlability: Robots.txt configuration, XML sitemap creation or auditing, crawl budget management, or Googlebot access issues
• Site Architecture: URL structure planning, information architecture, internal linking strategy, site depth optimization, or content siloing
• Indexation: Canonical tag implementation, noindex/nofollow directives, index bloat, duplicate content resolution, or Google Search Console index coverage issues
• Redirects: Redirect chain auditing, 301/302 strategy, redirect maps for site migrations, or HTTP-to-HTTPS migration
• JavaScript SEO: Client-side rendering issues, SSR vs CSR vs SSG evaluation, dynamic rendering, or JavaScript crawlability problems
• Mobile-First Indexing: Mobile rendering issues, mobile parity checks, responsive design auditing, or mobile usability errors
• Structured Data: Schema markup implementation (JSON-LD), rich result eligibility, schema validation, or structured data strategy
• Log File Analysis: Server log interpretation, crawl frequency analysis, crawl waste identification, or bot behavior auditing
• International SEO: Hreflang implementation, ccTLD vs subdomain vs subdirectory decisions, geotargeting, or multilingual site architecture
• Security: HTTPS migration, mixed content resolution, HSTS implementation, or security header configuration
• HTTP Status Codes: Diagnosing 4xx/5xx errors, soft 404 detection, server error patterns, or status code strategy
• Page Speed: Server response time (TTFB), render-blocking resources, image optimization, code splitting, or CDN configuration
• Site Migrations: Domain changes, platform migrations, HTTPS transitions, URL restructuring, or merger/acquisition site consolidation

Context efficiency

Heavy skill. Grep before Read any referenced file, then Read only matched ranges with offset + limit. List ${CLAUDE_PLUGIN_DATA}/<brand>/ before opening files. On re-invocation mid-session, skip files already in context.

Brand Context (Auto-Applied)

Before producing any marketing output from this module:

1. Check session context — The active brand summary was output at session start. Use the brand name, industry, voice settings, channels, goals, compliance, and competitors shown there.
2. If you need the full profile, read: ~/.claude-marketing/brands/{slug}/profile.json
3. Apply brand voice — Formality, energy, humor, authority levels must shape all content tone and word choices
4. Check compliance — Auto-apply rules for brand's target_markets and industry using skills/context-engine/compliance-rules.md
5. Reference industry benchmarks — Consult skills/context-engine/industry-profiles.md for the brand's industry
6. Use platform specs — Reference skills/context-engine/platform-specs.md for character limits and format requirements
7. Check campaign history — Run python "${CLAUDE_PLUGIN_ROOT}/scripts/campaign-tracker.py" --brand {slug} --action list-campaigns before planning new work
