When one bestseller takes most of the ad budget.

This example considers how to support the wider range when one product and branded searches dominate campaign results.

Illustrative scenario. No client identity or performance result is implied.

Amazon PPC portfolio context

Imagine a brand whose bestseller accounts for most ad-attributed sales. Other products receive less visibility, while branded searches drive much of the reported ROAS.

The team wants to grow the wider range, but budgets keep returning to the historical winner.

Branded demand and product concentration

We would separate branded and nonbrand results, then review spend, conversion, margin, and stock for each product.

We would assess relevant keyword tests and whether eligible Sponsored Brands or display campaigns could support other products using the available assets.

A broader campaign and product allocation plan

Keep a defined budget for established demand and separate tests for other products. Match each test to relevant searches, audiences, and landing pages.

Increase a product's budget only when its relevance, conversion, and margin support the change. Review the impact across the account.
