Marketing SEO Complete

SEO Technical and Marketing - Operational Skill

This skill contains actionable, production-ready systems for traditional search engine optimization:

• Technical SEO auditing (Core Web Vitals, crawlability, structured data, mobile optimization)
• SEO marketing strategy (keyword research, content planning, competitive analysis, brand building)
• Operational workflows (cross-team collaboration, stakeholder alignment, SEO OKRs)
• Total Search Optimization (Google, YouTube, Reddit, TikTok, forums, social SEO)

Structure: Technical fundamentals first -> Marketing strategy -> Operational execution -> Total Search Optimization.

For AI search optimization (ChatGPT, Perplexity, Gemini, AI Overviews, GEO): Use marketing-ai-search-optimization instead.

SEO vs GEO (Overlap Map)

Use this to avoid duplicating work across traditional SEO and AI answer engines.

Use marketing-seo-complete when

• You need crawl/indexation fixes, internal linking, sitemaps, canonicals, CWV/performance, structured data eligibility
• You want search demand capture (keywords), SERP strategy, link building, local/international SEO
• You need predictable technical and content operations that improve discoverability across search surfaces

Use marketing-ai-search-optimization when

• You care specifically about assistant visibility, citations, and “answer extraction” behavior (ChatGPT/Perplexity/Gemini/AIO)
• You are building entity pages, comparison pages, integration pages, and proof blocks optimized for quoting/citation
• You are measuring with a query bank and "share of model" rather than rankings

Note: For engineers building AEO monitoring platforms (API pipelines, citation databases, dashboards), see project-aeo-monitoring-tools — that's an engineering skill, not an SEO practitioner skill.

Use both when

• You want compounding discoverability (SEO) and compounding citation capture (GEO) with the same pages
• You are shipping high-intent pages (pricing, security, alternatives, integrations) and need both indexation + answer-ready structure

2026 Operating Assumptions (Evergreen)

• Prioritize usefulness and intent satisfaction; technical SEO cannot compensate for weak content.
• E-E-A-T matters most when claims can impact money, health, safety, or major decisions; for all niches, show real experience and verifiable proof where possible.
• Mobile-first is the default: performance, UX, and rendering on mobile are the primary gate.
• Crawl/indexation wins come from discoverability (internal links, sitemaps) and removing low-value crawl traps.
• Core Web Vitals are a weak signal but a strong tiebreaker; fix regressions and obvious failures.
• Structured data is for eligibility and rich results, not a ranking boost; use it to improve extraction and display.
• SERPs are multi-surface (web, video, local, forums, social); measure channel-by-channel, not only rankings.

Next.js Programmatic Reality (Build vs Discoverability)

• Static build artifact count is a deployment metric, not your SEO URL inventory.
• Discoverable/indexable scope comes from canonical URLs in sitemap plus internal linking and indexability signals.
• If generateStaticParams() causes build artifact explosion or ENOSPC, reduce pre-render scope first, keep long-tail URLs discoverable via sitemap.
• Use a hybrid model for high-cardinality sites: pre-render priority URLs, serve long-tail dynamically (SSR/ISR), keep canonical/hreflang/sitemap/internal links aligned.

Primary sources live in data/sources.json. For time-sensitive changes (core updates, reporting changes), use official sources first (Google Search Central / Search Status Dashboard); if your environment supports web search, refresh against current updates before giving definitive advice.

Key Thresholds (2026)

When NOT to Use

• AI platform content optimization (ChatGPT, Perplexity, Gemini visibility, citation strategy) -> Use marketing-ai-search-optimization
• AI monitoring platform engineering (building API pipelines, citation databases, dashboards) -> Use project-aeo-monitoring-tools
• Paid search campaigns (Google Ads, Bing Ads) -> Use marketing-paid-advertising
• Social media strategy (non-SEO focused) -> Use marketing-social-media
• Content creation process (writing, editing, publishing) -> Use marketing-content-strategy
• Email marketing -> Use marketing-email-automation

Quick Reference

10-Point Audit Framework

Every technical SEO audit follows this systematic checklist:

Scoring: Rate each area 0-10, calculate weighted average for overall Technical Health Score.

Decision Trees

### Audit Type Selection
Full site audit needed
  -> Use assets/audits/full-technical-audit.md
Quick issue check
  -> Use assets/audits/quick-audit-checklist.md
CWV-only deep dive
  -> Use assets/cwv/core-web-vitals-report.md
Schema validation only
  -> Use assets/schema/schema-validation-report.md

### Core Web Vitals Failing
LCP >2.5s
  -> Preload LCP element, optimize images, add CDN
  -> See references/core-web-vitals-guide.md
INP >200ms
  -> Reduce JavaScript, optimize event handlers
  -> See references/core-web-vitals-guide.md
CLS >0.1
  -> Add dimensions to images/ads, avoid layout shifts
  -> See references/core-web-vitals-guide.md

### Indexation Issues
Pages not indexed
  -> Check robots.txt blocking
  -> Verify sitemap inclusion
  -> Check canonical tags
  -> See references/crawlability-indexing.md
Crawl budget problems
  -> Remove low-value pages from crawl
  -> Fix redirect chains
  -> Optimize pagination
  -> See references/crawlability-indexing.md
New/large site needs fast indexation
  -> Internal linking (#1 accelerator)
  -> Manual GSC submission (10-20 priority pages)
  -> Real content updates (not fake lastmod)
  -> Brand mentions > backlinks (early stage)
  -> See references/crawlability-indexing.md#indexation-acceleration

Build fails from route explosion (ENOSPC / artifact limits)
  -> Reduce `generateStaticParams` scope to priority URLs
  -> Keep long-tail canonical URLs in sitemap
  -> Strengthen internal linking to top dynamic pages
  -> Validate indexation in GSC Coverage + URL Inspection

### Mobile Issues
Mobile-unfriendly
  -> Check viewport meta tag
  -> Verify responsive CSS
  -> Test touch target sizes
  -> See references/mobile-seo-guide.md

### Link Building Issues
Need more backlinks
  -> Create linkable assets (research, tools)
  -> Set up HARO/Featured.com
  -> Broken link building outreach
  -> See references/link-building-strategy.md
Low domain authority
  -> Focus on DA 50+ targets
  -> Digital PR campaigns
  -> Competitor backlink analysis
  -> See references/link-building-strategy.md

### Local SEO Issues
Not showing in local pack
  -> Optimize Google Business Profile
  -> Build local citations (NAP consistency)
  -> Generate more reviews
  -> See references/local-seo-guide.md
GBP not verified
  -> Complete verification process
  -> Ensure NAP matches website
  -> See references/local-seo-guide.md

### Security Issues
Mixed content warnings
  -> Update all HTTP resources to HTTPS
  -> See references/security-https-guide.md
SSL/TLS issues
  -> Run SSL Labs test
  -> See references/security-https-guide.md

GSC Issue Triage (Strict Output)

Use this format when diagnosing Google Search Console indexation and canonicalization statuses.

If missing context blocks a safe recommendation, ask only the minimum clarifying questions (example: "Should these URLs be indexed?").

For each issue:

• Issue:
• Severity: Critical / Moderate / Informational
• What Google Is Detecting:
• Why This Happens:
• Is This Against Google Rules? (Yes/No + Explanation):
• Safe Fix (Step-by-Step):
• Expected SEO Benefit:
• What NOT to Do (Important):

Trend Awareness Protocol

IMPORTANT: When users ask recommendation questions about SEO, refresh against current updates before giving definitive guidance. If your environment supports web search, use it. If not, rely on official sources in data/sources.json and ask the minimum clarifying question about timeframe/market (example: "Is this for the US market, and do you care about changes in the last 30/90 days?").

Trigger Conditions

• "What's the best approach for [Core Web Vitals/site speed/crawlability]?"
• "What should I focus on for SEO in 2026?"
• "What's the latest Google algorithm update?"
• "Current best practices for [structured data/mobile SEO/indexation]?"
• "Is [SEO technique] still relevant in 2026?"
• "How has Google Search changed recently?"
• "What Core Web Vitals thresholds should I target?"

Anti-Patterns

International Markets

This skill uses Google-centric defaults. For international SEO:

If you're using a router-based setup, mention country/region/search engine explicitly so the router can bring in marketing-geo-localization when needed.
