76% Ad-Attributed Revenue Growth and 21% ACOS Reduction for a Supplements Brand on Amazon

July 22, 2026

Executive Summary

Digisorus partnered with a growing Health & Personal Care brand to optimize its Amazon PPC campaigns. We took over the brand in mid-Q4 and began working on it in late November 2025. Throughout December, we implemented comprehensive optimizations, and the full effect of these changes was realized in January 2026. The result was a significant drop in ACOS alongside increased sales—a particularly challenging feat in the competitive Health & Personal Care niche where keeping profits moving in the right direction is a constant battle.

Over a 60-day period (December 1, 2025 – January 31, 2026), we restructured underperforming campaigns, cut inefficiencies, and implemented a scalable, profitable strategy.

Right Budget Allocation Strategy:

We identified keywords ranking in positions 10–20 with significant search volume and strategically pushed them into the top 5 positions. This was achieved with a minimal increase in spend relative to the efficiency gains. Simultaneously, we cut budgets from non-performing targets and reallocated those funds to the right targets, maximizing efficiency while keeping TACOS and overall spend under control to maximize profitability.

Note: All figures below represent ad-attributed revenue only.

Key Ad Revenue Outcomes

  1. Ad-attributed revenue: $18,433.49
  2. Revenue growth vs. prior period: +76%
  3. ACOS reduction: 20% (from 51% to 31.64%)
  4. ROAS improvement: +87% (from 1.69 to 3.16)
  5. Total purchases (via ads): 1,913
  6. CPC reduction: 31% (from $1.85 to $1.27)

    • Note: CPC was reduced through strategic bid optimization and achieving the right converting placements (TOS and ROS). This directly contributed to lower ACOS and better overall performance.

This result reflects a strategically structured and efficient advertising setup that positioned the brand for scalable PPC growth in a competitive supplements market.

The Challenge (Before Digisorus)

The brand’s Amazon PPC account had steady spend but low efficiency. Campaigns were unstructured, relied heavily on broad targeting, and lacked a negative keyword strategy, resulting in high ACOS and wasted ad spend.

 

Ad-Attributed Performance Before Engagement

Ad revenue: $10,500

Ad spend: $6,200

ACOS: 51%

ROAS: 1.69

Total purchases (via ads): 1,050

Average CPC: $1.85

Traffic quality: High impressions, low conversion efficiency

 

Core Issues Identified

  • Over-reliance on broad and auto campaigns
  • Poor keyword isolation and structure
  • No negative keyword strategy
  • Budget diluted across low-performing targets
  • Rising CPCs with declining efficiency

     

The brand was spending aggressively but failing to generate proportional ad-attributed revenue, limiting reinvestment potential.

Digisorus Strategy

Our approach focused on efficiency first, then controlled scaling, building a high-performing PPC structure.

  1. Campaign Restructuring

    Strategy:We performed a deep-dive analysis of search term impression share combined with key performance indicators (KPIs) to identify core gaps within our targeting. Based on this, we segmented campaigns by match type (Exact, Phrase, Broad), isolated high-converting search terms into new Exact campaigns, and separated branded vs. non-branded traffic. Budgets were then allocated based on clear performance tiers.

  1. Negative Keyword Refinement

    Strategy: Through deep analysis of search term reports, we systematically removed wasted spend from irrelevant queries. This immediate action reduced budget leakage from day one, ensuring every dollar was working toward profitable returns.
  1. Bid & Budget Optimization

    Strategy: We implemented dynamic bidding adjustments to maximize ROI, reducing bids on high-ACOS targets while increasing spend on profitable keywords. Daily budgets were scaled only after efficiency metrics had stabilized and proven consistent.
  1. CPC Control Strategy

    Strategy: By improving keyword quality alignment and strategically adjusting placement multipliers (TOS/ROS), we reduced competitive overbidding. This disciplined approach lowered our average CPC while maintaining—and often improving—ad placement visibility.

This “clean and scale” methodology stabilized performance and set the stage for profitable growth.

This demonstrates that the PPC investment was not only efficient in its own right but also a healthy driver of the brand’s overall revenue.

Key Takeaways

  • Efficiency first, scaling second:
    We improved ACOS and ROAS before increasing spend, ensuring a profitable foundation.
  • Structured PPC architecture:
     Campaign segmentation and negative keyword management drove measurable performance improvements.
  • Scalable growth achieved:
    Ad-attributed revenue increased significantly while maintaining TACOS discipline.
  • Profit-focused optimization:
    Lower CPC and higher conversion efficiency directly improved margins.

Conclusion

  • This case study highlights Digisorus’ expertise in transforming underperforming Amazon advertising accounts into efficient, scalable growth engines. Through strategic restructuring and disciplined execution, we delivered:

    1. Strong ad-attributed revenue growth
    2. Substantial ACOS reduction
    3. Sustainable ROAS improvement
    4. Higher purchase volume at a lower cost per click

    We do not simply increase ad spend—we optimize, structure, and scale campaigns strategically, delivering measurable and profitable results. For brands experiencing stagnant ad performance or high ACOS, the solution lies in smart strategy, not more spend.
