Stopping CPC blowups that wipe out efficient months

Challenge

In efficient months, the car speaker account ran at up to ~8.5× ROAS and another strong month near ~7.0×, with average CPC around ₹2.7–₹3.4. Blended across those efficient windows, ROAS sat near ~7.5×—proof the catalog can convert when spend stays disciplined.

Then waste months hit. In one period, average CPC jumped to roughly ₹36—about 13× the efficient level—while ROAS fell to ~0.4×. Other weak months stayed under 0.5–0.9×. Weekly keyword exports could not catch the bleed fast enough; winners and waste averaged into the same campaign totals.

Approach

With Sapyon, every keyword is scored continuously. Ranked recommendations surface pause-worthy waste, weak CPCs to lower, and converting terms to raise—so the team acts on the gap between ~₹3 efficient CPC and ~₹36 waste CPC before the month is lost.

Trusted rules automate repeat patterns (pause / bid down on chronic waste; protect winners), while managers keep approval on aggressive changes until the playbook is proven.

Results

The benchmark is the account’s own efficient state: up to 8.5× ROAS and ~7× months at ~₹3 CPC. The risk to eliminate is waste months under 0.5× ROAS when CPC inflates without continuous scoring.

If you run car audio on Amazon, you already know both sides of this chart. Sapyon is how you stay on the efficient side—without hiring someone to live in search-term reports.
