While almost half of all consumers browse via their phones, only 1 in 5 complete transactions on mobile (page 5). • Optimal load times for peak conversions ranged from 1.8 to 2.7 seconds across device types (page 6). • Just a 100-millisecond delay in load time hurt conversion rates by up to 7% (page 7). • Bounce rates were highest among mobile shoppers and lowest among those using tablets (page 9). • Optimal load times for lowest bounce rates ranged from 700ms to 1.2s across all device types (page 10). • A two-second delay in load time hurt bounce rates by up to 103% (page 10). • Pages with the lowest bounce rates had start render times ranging from 0.9 to 1.5 seconds (page 12). • A two-second delay correlated with up to a 51% decrease in session length (page 14).
