For many brands, the first instinct when Amazon sales begin to plateau is to increase advertising. Launch more Sponsored Products campaigns. Expand Amazon DSP. Increase bids on high-volume keywords. Invest more in Amazon PPC management. While advertising certainly plays a critical role in Amazon growth, it isn’t always the right place to start.
In fact, one of the most common reasons Amazon advertising underperforms has nothing to do with campaign strategy. It has everything to do with the condition of the Amazon channel itself. Duplicate listings, unauthorized resellers, inconsistent pricing, fragmented catalogs, poor listing content, and weak brand control can all limit advertising performance before a single ad is ever served. This is why experienced Amazon agencies often recommend completing an Amazon channel cleanup before investing heavily in advertising. A clean, well-managed channel provides the foundation that allows every advertising dollar to work harder.
What Is Amazon Channel Cleanup?
Amazon channel cleanup is the process of organizing, optimizing, and gaining control over a brand’s Amazon presence before focusing on growth initiatives. Rather than immediately launching advertising campaigns, brands first address the issues that create friction throughout the customer journey. Channel cleanup often includes:
- Merging duplicate ASINs
- Removing redundant or underperforming listings
- Establishing Brand Registry ownership
- Optimizing product listings
- Creating A+ Content
- Building an Amazon Brand Store
- Managing unauthorized resellers
- Improving Buy Box ownership
- Standardizing pricing strategies
- Organizing product variations
- Simplifying catalog structure
The goal isn’t simply to create a cleaner catalog; it’s to build an Amazon storefront that converts traffic efficiently once advertising begins driving customers to it.
Why Advertising Can’t Fix Structural Problems
Many brands assume that weak sales are caused by a lack of traffic.
Sometimes that’s true. But in many cases, traffic isn’t the issue. The shopping experience is.
If customers arrive on duplicate listings with inconsistent content, unclear product information, poor images, or unstable pricing, additional advertising simply sends more shoppers into the same inefficient buying experience.
Advertising increases visibility. It doesn’t solve operational problems.
That’s why brands often see rising advertising costs without proportional revenue growth when foundational issues remain unresolved.
Common Channel Issues That Reduce Advertising Performance
Several Amazon channel problems directly impact advertising efficiency.
Duplicate ASINs
Duplicate listings divide reviews, sales history, and organic ranking signals across multiple products. Instead of building authority behind one strong listing, brands unintentionally weaken all of them.
Unauthorized Resellers
When unauthorized sellers frequently win the Buy Box, brands can end up paying to advertise products they don’t fully control. That creates inconsistent customer experiences while reducing the return on advertising investment.
Poor Listing Optimization
Even highly targeted advertising campaigns struggle when product listings fail to convert shoppers. Weak product titles, incomplete bullet points, missing A+ Content, and low-quality imagery all reduce conversion rates.
Catalog Fragmentation
Multiple similar SKUs competing for the same search terms often increase advertising costs while reducing overall efficiency. Instead of reinforcing one another, products begin competing internally.
Why Brand Control Matters Before Growth
Before scaling Amazon advertising, brands should understand who controls their presence within the marketplace. Questions worth asking include:
- Are we consistently winning the Buy Box?
- Are unauthorized resellers affecting pricing?
- Do all listings accurately represent the brand?
- Is Brand Registry fully implemented?
- Are duplicate listings creating confusion?
- Is our Brand Store optimized?
Without control, advertising often becomes an expensive attempt to compensate for problems elsewhere in the channel.
Better Data Leads to Better Advertising Decisions
Channel cleanup isn’t only about fixing problems. It’s also about creating better visibility into performance. Once listings, pricing, catalog structure, and ownership are organized, brands can begin making smarter decisions based on accurate data. That includes:
- Keyword performance
- Buy Box trends
- Product profitability
- Customer purchasing behavior
- Market basket analysis
- Advertising attribution
These insights allow brands to prioritize products that generate the strongest long-term business impact rather than simply increasing advertising spend across the entire catalog.
How Ricola Built a Stronger Amazon Channel Before Scaling Advertising
A strong example of this approach comes from WBX’s Commerce’s’s work with Ricola. Although Ricola has been a trusted household name for nearly a century, much of its business had historically been built through traditional retail. As the company expanded into Amazon, it needed more than advertising; it needed a channel designed for ecommerce success.
Cleaning Up the Amazon Channel
Rather than immediately increasing advertising spend, WBX first focused on creating a stronger operational foundation.
The team executed a comprehensive Amazon channel cleanup by merging duplicate ASINs, narrowing the catalog to emphasize the most profitable SKUs, optimizing product listings, establishing brand ownership, and creating enhanced A+ Content and an Amazon Brand Store. These improvements gave Ricola greater control over its Amazon presence while creating a more consistent customer experience.
Regaining Buy Box Control
Using WBX Insights, WBX identified products that were consistently losing the Buy Box to resellers. By monitoring pricing trends and marketplace activity, the team implemented strategies that improved Buy Box ownership and strengthened Ricola’s control over its products before investing heavily in advertising. This ensured advertising budgets would support Ricola’s own growth rather than unintentionally benefiting competing sellers.
Using Customer Data to Drive Smarter Growth
Once the foundation was established, WBX leveraged proprietary data to guide future optimization. Trending keyword reports helped identify opportunities to improve visibility. Market basket analysis revealed which products customers naturally purchased together, helping inform future multipack strategies.
Halo reporting identified which products generated additional purchases across the catalog, allowing advertising budgets to be concentrated where they produced the greatest overall business impact.
Virtual bundles were also tested before permanent multipacks were introduced, allowing the team to validate customer demand while minimizing operational costs.
Stronger Foundations Produced Stronger Results
Because Ricola’s Amazon channel had been cleaned up before advertising became the primary focus, every optimization built upon a stronger foundation. Instead of trying to overcome duplicate listings, reseller challenges, and catalog inefficiencies with larger advertising budgets, WBX first resolved the structural issues limiting growth. The result was a more efficient Amazon business that achieved a 57% year-over-year increase in Amazon sales, demonstrating that sustainable growth begins with channel control, not simply higher advertising spend.
Advertising Performs Better When the Foundation Is Strong
Once an Amazon channel has been properly optimized, advertising becomes significantly more effective.
Brands often experience:
- Higher conversion rates
- Better return on ad spend (ROAS)
- Lower customer acquisition costs
- Improved organic rankings
- Stronger Buy Box ownership
- More efficient budget allocation
- Greater long-term profitability
Rather than compensating for operational issues, advertising reinforces an already optimized customer experience.
What This Means for Your Amazon Strategy
If your Amazon advertising isn’t delivering the results you expect, the solution may not be increasing your budget.
It may be improving your foundation.
Before scaling Amazon PPC or Amazon DSP campaigns, consider asking:
- Do we fully control our Amazon channel?
- Are duplicate listings reducing performance?
- Are unauthorized resellers affecting pricing?
- Are our listings optimized for conversion?
- Is our catalog structured around customer buying behavior?
- Are we directing advertising budgets toward our highest-value products?
For many brands, answering these questions unlocks greater growth than simply spending more on ads.
Conclusion: Growth Starts with a Strong Foundation
Successful Amazon advertising begins long before campaigns are launched. It starts with building a channel that is organized, optimized, and under the brand’s control.
As the Ricola case study demonstrates, cleaning up an Amazon channel creates the foundation for stronger advertising performance, better customer experiences, improved marketplace control, and sustainable long-term growth. By resolving structural issues before scaling advertising, brands position themselves to generate more value from every marketing dollar they invest.
Before increasing your Amazon advertising budget, make sure your channel is ready to support it.
