Your customer clicks your ad. 3 seconds pass. 4 seconds. 5 seconds.
At 6 seconds, they're gone forever.
Here's what just happened: You paid $3.50 for that click, and slow loading speed handed your customer to a competitor.
The Speed-Revenue Connection
1-second delay = 7% fewer conversions
2-second delay = 19% fewer conversions
3-second delay = 40% higher bounce rate
5+ seconds = 90% abandonment rate
For a $10M brand, each second of load time equals roughly $2.5M in lost annual revenue.

The 3-Second Rule
Your entire page—images, scripts, everything—must load in under 3 seconds on mobile.
Not "mostly loaded." Not "above the fold." Completely functional.
