Amazon PPC case study · US marketplace

A great product.
A broken ad account.

Kubo Tea converted exceptionally well. The problem was how the ads reached shoppers—broad targeting, wasted spend, and the wrong audience.

The challenge

The listing was working.
The advertising was not.

Kubo Tea's strongest products converted at roughly 40%. Yet the audit found 51% ACoS, expensive clicks, irrelevant traffic, and only 7% new-to-brand orders.

90-day advertising auditOct 2024–Jan 2025
18% conversion rateshould not coexist with 51% ACoS. The gap was structural.

Broad targeting reached the wrong shoppers.

Spend leaked into low-intent searches and unrelated product formats.

A $15 product was paying too much per click.

vCPM bidding produced effective click costs above $10 on some display targets.

Most ad spend reached existing customers.

Only 7% of ad-attributed orders were new-to-brand, limiting genuine acquisition.

What we changed

Control the traffic.
Then scale what converts.

We rebuilt the account around precision, relevance, and a clear weekly optimisation rhythm.

01

Built precise negative targeting

Removed irrelevant searches and protected budget for real purchase intent.

02

Moved Sponsored Display from vCPM to CPC

Optimised for actions rather than paying for low-value impressions.

03

Isolated top keywords into exact match

Captured high-intent demand and gained direct bid control.

04

Introduced weekly optimisation

Reviewed bids, budgets, search terms, and underperforming targets every week.

The results

Lower ACoS.
Higher sales. Better scale.

Spend increased by 5.2%, while purchases grew 11.4% and ad-attributed sales rose 11.9%. The account became more efficient as it scaled.

More revenue from proportionally less spend.

The rebuild did not rely on cutting visibility. Impressions, clicks, purchases, and sales all increased while ACoS continued to fall.

Spend increased by 5.2%. Purchases grew by 11.4%. Ad sales grew by 11.9%. ACoS fell.

The takeaway

The product had always been there. The advertising just needed to find the right people.

A 0.02% CTR was a targeting problem. A $10 click on a $15 product was a bidding problem. Once the structure was corrected, profitable growth followed.
