---name: seo-fundamentalsdescription: Core principles of SEO including E-E-A-T, Core Web Vitals, technical foundations, content quality, and how modern search engines evaluate pages.risk: safesource: communitydate_added: '2026-02-27'--- --- # SEO Fundamentals > **Foundational principles for sustainable search visibility.**> This skill explains _how search engines evaluate quality_, not tactical shortcuts. --- ## 1. E-E-A-T (Quality Evaluation Framework) E-E-A-T is **not a direct ranking factor**.It is a framework used by search engines to **evaluate content quality**, especially for sensitive or high-impact topics. | Dimension             | What It Represents                 | Common Signals                                      || --------------------- | ---------------------------------- | --------------------------------------------------- || **Experience**        | First-hand, real-world involvement | Original examples, lived experience, demonstrations || **Expertise**         | Subject-matter competence          | Credentials, depth, accuracy                        || **Authoritativeness** | Recognition by others              | Mentions, citations, links                          || **Trustworthiness**   | Reliability and safety             | HTTPS, transparency, accuracy                       | > Pages competing in the same space are often differentiated by **trust and experience**, not keywords. --- ## 2. Core Web Vitals (Page Experience Signals) Core Web Vitals measure **how users experience a page**, not whether it deserves to rank. | Metric  | Target  | What It Reflects    || ------- | ------- | ------------------- || **LCP** | < 2.5s  | Loading performance || **INP** | < 200ms | Interactivity       || **CLS** | < 0.1   | Visual stability    | **Important context:** - CWV rarely override poor content- They matter most when content quality is comparable- Failing CWV can _hold back_ otherwise good pages --- ## 3. Technical SEO Principles Technical SEO ensures pages are **accessible, understandable, and stable**. ### Crawl & Index Control | Element           | Purpose                || ----------------- | ---------------------- || XML sitemaps      | Help discovery         || robots.txt        | Control crawl access   || Canonical tags    | Consolidate duplicates || HTTP status codes | Communicate page state || HTTPS             | Security and trust     | ### Performance & Accessibility | Factor                 | Why It Matters                || ---------------------- | ----------------------------- || Page speed             | User satisfaction             || Mobile-friendly design | Mobile-first indexing         || Clean URLs             | Crawl clarity                 || Semantic HTML          | Accessibility & understanding | --- ## 4. Content SEO Principles ### Page-Level Elements | Element          | Principle                    || ---------------- | ---------------------------- || Title tag        | Clear topic + intent         || Meta description | Click relevance, not ranking || H1               | Page’s primary subject       || Headings         | Logical structure            || Alt text         | Accessibility and context    | ### Content Quality Signals | Dimension   | What Search Engines Look For || ----------- | ---------------------------- || Depth       | Fully answers the query      || Originality | Adds unique value            || Accuracy    | Factually correct            || Clarity     | Easy to understand           || Usefulness  | Satisfies intent             | --- ## 5. Structured Data (Schema) Structured data helps search engines **understand meaning**, not boost rankings directly. | Type           | Purpose                || -------------- | ---------------------- || Article        | Content classification || Organization   | Entity identity        || Person         | Author information     || FAQPage        | Q&A clarity            || Product        | Commerce details       || Review         | Ratings context        || BreadcrumbList | Site structure         | > Schema enables eligibility for rich results but does not guarantee them. --- ## 6. AI-Assisted Content Principles Search engines evaluate **output quality**, not authorship method. ### Effective Use - AI as a drafting or research assistant- Human review for accuracy and clarity- Original insights and synthesis- Clear accountability ### Risky Use - Publishing unedited AI output- Factual errors or hallucinations- Thin or duplicated content- Keyword-driven text with no value --- ## 7. Relative Importance of SEO Factors There is **no fixed ranking factor order**.However, when competing pages are similar, importance tends to follow this pattern: | Relative Weight | Factor                      || --------------- | --------------------------- || Highest         | Content relevance & quality || High            | Authority & trust signals   || Medium          | Page experience (CWV, UX)   || Medium          | Mobile optimization         || Baseline        | Technical accessibility     | > Technical SEO enables ranking; content quality earns it. --- ## 8. Measurement & Evaluation SEO fundamentals should be validated using **multiple signals**, not single metrics. | Area        | What to Observe            || ----------- | -------------------------- || Visibility  | Indexed pages, impressions || Engagement  | Click-through, dwell time  || Performance | CWV field data             || Coverage    | Indexing status            || Authority   | Mentions and links         | --- > **Key Principle:**> Sustainable SEO is built on _useful content_, _technical clarity_, and _trust over time_.> There are no permanent shortcuts. ## When to UseThis skill is applicable to execute the workflow or actions described in the overview. ## Limitations- Use this skill only when the task clearly matches the scope described above.- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
