# 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](../marketing-ai-search-optimization/SKILL.md) 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](../project-aeo-monitoring-tools/SKILL.md) — 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)

| Metric | Target | Impact |
|--------|--------|--------|
| LCP | < 2.5s | Mobile-first indexing threshold |
| INP | < 200ms | Replaced FID; user engagement signal |
| CLS | < 0.1 | Layout stability; ranking factor |
| TTFB | < 600ms | Crawl rate: slow servers often reduce pages crawled/day |
| Mobile score | > 90 | Required for competitive rankings |

---

## When NOT to Use

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

## Decision Trees

```text
### 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?"

### Required Searches

1. Search: `site:developers.google.com search updates`
2. Search: `Google Search Status Dashboard`
3. Search: `Core Web Vitals thresholds INP`
4. Search: `Search Console new features`

### What to Report

After searching, provide:

- **Current landscape**: What SEO factors matter most NOW (not 6 months ago)
- **Emerging trends**: New ranking signals or Google features
- **Deprecated/declining**: Techniques that no longer work or hurt rankings
- **Recommendation**: Based on fresh data and recent algorithm updates

### Example Topics (verify with fresh search)

- Core Web Vitals updates (INP replacing FID, thresholds)
- Google algorithm updates (helpful content, spam updates)
- Structured data new types and requirements
- Mobile-first indexing changes
- AI Overviews impact on traditional search
- New Search Console features
