How it is calculated
Sales before = traffic × current conversion ÷ 100, sales after = traffic × new conversion ÷ 100. Sales uplift = sales after − sales before. Uplift in percent = (new conversion − current conversion) ÷ current conversion × 100% — that's the relative growth of conversion itself, not an absolute difference in percentage points.
The key assumption is that traffic stays constant: the whole effect is attributed to the conversion improvement alone, not to a change in traffic volume or quality. This is handy for isolating the effect of a specific site change (e.g. a checkout page redesign) from marketing factors.
In practice even a small rise in conversion in percentage points can mean a sizeable relative sales increase if the baseline conversion is low — for example, going from 2% to 2.5% looks modest in points but is a 25% jump in sales count.
