Paid media basics

Spend on paid ads only what your margin per order can absorb while you learn your real acquisition cost.
This Launch Direct guide, published by Cydney Mar, explains how to size a first ad budget, how to read acquisition cost against margin, and why the product and pricing come before media spend. Paid media amplifies whatever you launch, including a margin that does not work.
Start with a small, fixed test budget and treat it as the cost of learning your acquisition cost, not as a launch campaign.
The right number depends on your contribution per order. Run your figures through the margin calculator with acquisition cost at 0 to see what each order earns before marketing; that figure is roughly the most you can pay to win a first order without losing money on it. Spend above that only if repeat purchases are proven.
The numbers
Published figures show buying customers has become more expensive, while community and repeat buyers lower the blended cost.
Procedure
Calculate contribution per order before marketing. That is your break-even acquisition cost.
Run a modest, fixed budget across one or two messages to one audience. Change one thing at a time.
Divide spend by new orders. Watch returns too: a refunded order did not really get acquired.
Increase spend only on what lands below your ceiling, and recheck as costs and returns move.
