Their words “All metrics shown are medians (not averages) to avoid skew from outliers.”
3 · What we leave out
The page has more figures than the ones we use.
The page defines none of its metrics. We read its CAC and its conversion rate as the same division as ours.
The page also gives medians by industry and by price. A brand in the Forum has no industry yet, so we use the bands of GMV.
It also gives average order value, new-customer ROAS, add-to-cart rate and cart-to-purchase rate. We don’t compare with them.
