How the maths works
Why 30%?
Walmart, Amazon, and dozens of independent studies show the same thing: every extra second of mobile load time drops conversions by 7-30%. Slow + ugly = compounding loss.
What's a "slow" site?
Anything over 3 seconds on mobile, anything that doesn't render properly first try, anything where the buttons are too small to tap. Run a real audit to see if yours qualifies.
What if my conversion isn't 2%?
Adjust the slider. If you don't track conversions, 2% is the safe-bet UK SMB average. Most local-services businesses are 1-3%.
