FAQ

Does a small per-unit fee increase matter in practice?

Yes. For lower-ticket products, small fixed fee increases can materially reduce contribution margin.

Which SKUs should be reviewed first?

Start with high GMV + low margin SKUs, then move to high ad dependency products.

Should I pause ads immediately?

Pause only SKUs below minimum margin threshold after recalculation; keep profitable campaigns running.
