No cheers, no fluff - just the harsh truth: every dollar you spend without tracking its return is wasted. I realized this after dropping thousands on ads that “seemed right” but generated zero return. Once I started tracking data from https://flowium.com/blog/ecommerce-metrics/, I saw where there were leaks in my funnel and fixed them. Data isn`t just numbers on a screen; it`s your map to sustainable growth. Ignore it, and you`ll get lost before you even begin the journey.
