Find What's Really Eating Your Profit — Before a Quick Fix Costs You More

Your profit dropped last week. Before you touch your ads — check what else changed.

Very often the cause isn't advertising at all: it's a price change, a warehouse fee, or a spike in refunds. Change your ads based on a wrong diagnosis — and you risk breaking a working campaign and losing your organic ranking

Example 1:

A seller saw profit per unit drop to −$51 — the product usually earned $13. He told his ad specialist to rework the campaigns — bids were lowered, two campaigns paused.

But ACOS was 19%, right at its 18% median. The ads were fine.

The real cause: Amazon charged a $457 warehouse fee that week (every other week: $0), and refunds spiked to $890 (average: $210).

By the time the seller realized, a competitor had taken his top keyword — $2,500–$5,700 in lost sales over two weeks, plus weeks to rebuild organic ranking.

Example 2:

A seller saw ACOS jump from 18% to 38% and profit drop by half. He told his ad specialist to fix the campaigns — bids were lowered, keywords rewritten.

But the real cause was a price change: someone on his team had raised it from $130 to $164, conversion dropped, and ACOS doubled. The ads had been fine all along.

By the time the seller realized, a competitor had taken his keyword — $3,000+ in lost sales, weeks to recover.

Stop Funding Products
That Drain Your Profit Every Month

If a product brings high profit per unit, it makes sense to invest in it — buy more inventory, create more variations, scale it.

Where to find the capital? Reallocate it from products that earn close to nothing per unit — several times less than your top sellers

Example:

A seller looked at his quarterly numbers and saw one product earning $2, $3, $1, −$2 per unit — quarter after quarter. Median: $1.50, barely above zero.

The product next to it: $18, $17, $19, $16. He'd been spending the same effort on both — same ad budget, same inventory tied up.

That was 4 quarters of $15,000+ in frozen capital, ad spend, and management time on a product that earned almost nothing — while his best seller could have used that capital to grow.

What to track:

Switch to Quarterly or Yearly view to see long-term patterns.

Expand PnL (profit) per piece — check which products have consistently low or negative values.

Compare Median across products — a low or negative median means it's a pattern, not a one-time dip.
