The 200 Ranking Factors Myth
SEO industry obsessed over “200+ ranking factors,” but in reality:
- Quality, relevant content
- Backlinks from authoritative sites
- Technical site health
- User experience signals

…mattered far more than minor factors.
Content is King (But Distribution is Queen)
Brian Dean’s Skyscraper Technique (2015) popularized:

But creating great content without promotion still failed.
