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.
