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.

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

There is no fixed ranking factor order.
However, when competing pages are similar, importance tends to follow this pattern:

Medium

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.
