With 1-second delay reducing conversions by 7% dan 53% of mobile users abandoning sites that take longer than 3 seconds to load, mastering page speed dan UX optimization adalah essential untuk successful landing page optimization dan digital marketing performance.
Artikel ini akan mengupas tuntas page speed dan UX optimization untuk membantu sobat pembaca understand performance principles, implement optimization strategies, dan leverage technical improvements untuk superior conversion results dan user satisfaction.
Page Speed & UX Overview
Performance Impact on Conversions
Understanding Speed-Conversion Relationship: Page speed directly affects user behavior, search rankings, dan conversion rates. Faster websites provide better user experiences, reduce bounce rates, dan increase the likelihood of users completing desired actions. The relationship between speed dan conversions is exponential, dengan even small improvements yielding significant results.
Performance Statistics:
Speed Impact Data:
Conversion Impact:
- 1-second delay = 7% conversion reduction
- 2-second delay = 15% conversion reduction
- 3-second delay = 32% conversion reduction
- 5-second delay = 90% conversion reduction
- 10-second delay = 123% conversion reduction
User Behavior:
- 53% mobile users abandon slow sites
