This guide reveals how the 4 UX pillars (navigation clarity, page speed, mobile-first, accessibility) directly impact your Google ranking and conversions.

Critical Core Web Vitals:

Signals measured:

• Bounce rate (rises drastically >3s)
• Average session duration
• Pages per session

Impact:

Fast (<1s): 35% bounce rate

Medium (1-3s): 54% bounce rate

Slow (>3s): 75% bounce rate

Difference: -40 bounce points = Quality signal boost

Pillar 3: Mobile-First UX

Mechanics: 60%+ of traffic comes from mobile

Optimizations:
