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.
