E-E-A-T (Quality Evaluation Framework)\n\nE-E-A-T is **not a direct ranking factor**.\nIt is a framework used by search engines to **evaluate content quality**, especially for sensitive or high-impact topics.\n\n| Dimension             | What It Represents                 | Common Signals                                      |\n| --------------------- | ---------------------------------- | --------------------------------------------------- |\n| **Experience**        | First-hand, real-world involvement | Original examples, lived experience, demonstrations |\n| **Expertise**         | Subject-matter competence          | Credentials, depth, accuracy                        |\n| **Authoritativeness** | Recognition by others              | Mentions, citations, links                          |\n| **Trustworthiness**   | Reliability and safety             | HTTPS, transparency, accuracy                       |\n\n> Pages competing in the same space are often differentiated by **trust and experience**, not keywords.\n\n---\n\n## 2. Core Web Vitals (Page Experience Signals)\n\nCore Web Vitals measure **how users experience a page**, not whether it deserves to rank.\n\n| Metric  | Target  | What It Reflects    |\n| ------- | ------- | ------------------- |\n| **LCP** | < 2.5s  | Loading performance |\n| **INP** | < 200ms | Interactivity       |\n| **CLS** | < 0.1   | Visual stability    |\n\n**Important context:**\n\n- CWV rarely override poor content\n- They matter most when content quality is comparable\n- Failing CWV can _hold back_ otherwise good pages\n\n---\n\n## 3. Technical SEO Principles\n\nTechnical SEO ensures pages are **accessible, understandable, and stable**.\n\n### Crawl & Index Control\n\n| Element           | Purpose                |\n| ----------------- | ---------------------- |\n| XML sitemaps      | Help discovery         |\n| robots.txt        | Control crawl access   |\n| Canonical tags    | Consolidate duplicates |\n| HTTP status codes | Communicate page state |\n| HTTPS             | Security and trust     |\n\n### Performance & Accessibility\n\n| Factor                 | Why It Matters                |\n| ---------------------- | ----------------------------- |\n| Page speed             | User satisfaction             |\n| Mobile-friendly design | Mobile-first indexing         |\n| Clean URLs             | Crawl clarity                 |\n| Semantic HTML          | Accessibility & understanding |\n\n---\n\n## 4. Content SEO Principles\n\n### Page-Level Elements\n\n| Element          | Principle                    |\n| ---------------- | ---------------------------- |\n| Title tag        | Clear topic + intent         |\n| Meta description | Click relevance, not ranking |\n| H1               | Page’s primary subject       |\n| Headings         | Logical structure            |\n| Alt text         | Accessibility and context    |\n\n### Content Quality Signals\n\n| Dimension   | What Search Engines Look For |\n| ----------- | ---------------------------- |\n| Depth       | Fully answers the query      |\n| Originality | Adds unique value            |\n| Accuracy    | Factually correct            |\n| Clarity     | Easy to understand           |\n| Usefulness  | Satisfies intent             |\n\n---\n\n## 5. Structured Data (Schema)\n\nStructured data helps search engines **understand meaning**, not boost rankings directly.\n\n| Type           | Purpose                |\n| -------------- | ---------------------- |\n| Article        | Content classification |\n| Organization   | Entity identity        |\n| Person         | Author information     |\n| FAQPage        | Q&A clarity            |\n| Product        | Commerce details       |\n| Review         | Ratings context        |\n| BreadcrumbList | Site structure         |\n\n> Schema enables eligibility for rich results but does not guarantee them.\n\n---\n\n## 6. AI-Assisted Content Principles\n\nSearch engines evaluate **output quality**, not authorship method.\n\n### Effective Use\n\n- AI as a drafting or research assistant\n- Human review for accuracy and clarity\n- Original insights and synthesis\n- Clear accountability\n\n### Risky Use\n\n- Publishing unedited AI output\n- Factual errors or hallucinations\n- Thin or duplicated content\n- Keyword-driven text with no value\n\n---\n\n## 7. Relative Importance of SEO Factors\n\nThere is **no fixed ranking factor order**.\nHowever, when competing pages are similar, importance tends to follow this pattern:\n\n| Relative Weight | Factor                      |\n| --------------- | --------------------------- |\n| Highest         | Content relevance & quality |\n| High            | Authority & trust signals   |\n| Medium          | Page experience (CWV, UX)   |\n| Medium          | Mobile optimization         |\n| Baseline        | Technical accessibility     |\n\n> Technical SEO enables ranking; content quality earns it.\n\n---\n\n## 8. Measurement & Evaluation\n\nSEO fundamentals should be validated using **multiple signals**, not single metrics.\n\n| Area        | What to Observe            |\n| ----------- | -------------------------- |\n| Visibility  | Indexed pages, impressions |\n| Engagement  | Click-through, dwell time  |\n| Performance | CWV field data             |\n| Coverage    | Indexing status            |\n| Authority   | Mentions and links         |\n\n---\n\n> **Key Principle:**\n> Sustainable SEO is built on _useful content_, _technical clarity_, and _trust over time_.\n> There are no permanent shortcuts.\n\n## When to Use\nThis skill is applicable to execute the workflow or actions described in the overview.\n\n## Limitations\n- Use this skill only when the task clearly matches the scope described above.\n- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.\n- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.","tags":["seo","fundamentals","antigravity","awesome","skills","sickn33"],"capabilities":["skill","source-sickn33","category-antigravity-awesome-skills"],"categories":["antigravity-awesome-skills"],"synonyms":[],"warnings":[],"endpointUrl":"https://skills.sh/sickn33/antigravity-awesome-skills/seo-fundamentals","protocol":"skill","transport":"skills-sh","auth":{"type":"none","details":{"install_from":"skills.sh"}},"qualityScore":"0.300","qualityRationale":"deterministic
