Mirai Clinical’s Journey

Short Introduction:

Mirai Clinical came to AMZOS with a common problem: strong products, but ad spend that wasn’t translating into visibility or sales on Amazon. Within six months of a restructured Amazon PPC campaign, daily revenue grew from $539 to $5,344, a tenfold increase, while keeping Advertising Cost of Sales (ACoS) at a lean 13%. This Amazon PPC case study breaks down exactly how that happened.

Client Background:

Mirai Clinical is a health and wellness brand specializing in products that address nonenal, a body odor associated with aging. Their skincare and hygiene line targets a specific, underserved need in personal care.

The Challenge:

Before working with AMZOS, Mirai Clinical struggled to reach the right audience on Amazon. Their ad spend wasn’t being allocated efficiently, and their product messaging wasn’t translating into the kind of brand visibility that drives consistent sales. Like many niche brands, they needed Amazon PPC management built around a very specific buyer, not a broad category.

Our Strategy:

The core problem wasn’t ad spend, it was precision. Nonenal is a niche, specific search term, and generic skincare keywords aren’t reaching the shoppers actually searching for a solution to that exact problem. The strategy centered on three things:

• Refining keyword targeting around nonenal-specific search terms, rather than broader skincare categories
• Rewriting ad creative to address the specific problem Mirai Clinical’s products solve directly
• Making ongoing bid adjustments based on real performance data, rather than setting bids once and leaving them

A conservative starting budget was deliberate. It gave the Amazon PPC campaign room to collect real performance data before scaling spend, so growth was driven by what was actually working, not by guesswork.

Services Provided:

• Amazon PPC campaign strategy and setup
• Keyword research and targeting refinement
• Ad creative development
• Ongoing bid management and campaign optimization

Results & Business Impact:

A 10x increase in daily revenue is a strong result on its own. Maintaining a 13% total ACoS while scaling that aggressively is the more telling number. It shows the growth came from better targeting and campaign efficiency, not from simply increasing ad spend to chase sales, exactly the kind of Amazon PPC management results a niche brand needs to grow sustainably.

Key Takeaways:

• Niche, specific products often need niche, specific keyword targeting, not broad category terms
• A conservative launch budget can accelerate results by generating the data needed to scale intelligently
• Revenue growth means little without efficiency. A low ACoS during rapid growth is a sign the strategy is working, not just the budget
