312% Sales Growth & 5.8x ROAS with Amazon PPC

One of the major issues Amazon sellers face is scaling ads without ROAS falling apart. Expenses rise, sales decline, and ROAS becomes unpredictable. This is exactly what we had to manage for an Amazon seller. His budget was leaking out, campaigns were mismanaged, and the PPC setup wasn't organised to scale.

With more competition and rising costs, it can be an alarming situation for any seller. To fix this, we needed to rebuild the account with a full-funnel PPC structure, narrow down the audience, refine keyword selection, and shift budget towards what was performing. Eventually, this resulted in 312% sales growth with 5.8x ROAS.

If you also feel like your PPC performance is stuck, 10X Commerce can audit your account. Our in-house niche-specific experts provide customised solutions for brands whose sales have plateaued, which in turn boost sales, improve visibility, and drive steady growth.

 

Why Most Amazon PPC Campaigns Fail to Scale Beyond 2x ROAS

Sellers begin to gain recognition with Amazon PPC campaigns; however, 2x ROAS, the transition from profitability to growth alters the dynamics. After spending a significant amount on PPC, expecting an appreciable ROAS is normal. Only focusing on ROAS while neglecting the internal metrics pushes you back in the competition.

Here are a few common mistakes sellers usually make:

• One of the biggest Amazon PPC failure reasons is mixing the well-performing and weaker products in the same campaign. The strong keywords take all the budget, and the weak ones remain hidden.


• Another common PPC campaign mistake on Amazon is adding multiple SKUs to a single ad group, which reduces impressions per SKU. The data stays thin, and Amazon struggles to promote the right ads.


• One frequent Amazon advertising error is mixing branded and non-branded traffic. Branded ads perform well because of customer trust, while non-branded ads waste spend.


• Copying SKAGs without any clear goal. You end up with a low-performing and difficult-to-manage account.


• Running uncoordinated ads causes an overlap, which means your ads end up competing against each other. CPC rises, and you pay more for the same traffic.


• Weak negative keyword control also makes Amazon ads underperform. Irrelevant searches consume your budget and drop conversion, eventually stalling ROAS.


• A common cause of low ROAS in Amazon ads is spreading the budget across too many campaigns so that even good campaigns can't gather enough conversions to stabilise and improve.

 

The Brand Audit: Understanding the Baseline Before We Spent a Dollar

• PPC experts performed an Amazon PPC account audit, which includes a deeper analysis of the ad campaigns, keywords, bids, ACoS, ROAS, and budgets to find and fill gaps.
• Performed sponsored ads performance audit to identify "leaks" in campaigns, high ACoS, weak keywords, and missed revenue opportunities.
• To evaluate targeting, sales, and trends, an audit of Amazon ad account for the last 30-60 days.
• A baseline PPC analysis was conducted to refine essential performance standards, facilitating evaluation of future optimisation.
• A pre-campaign Amazon audit of account readiness and listing quality. This helps build a strong foundation before ad spend scaling.

 

Full-Funnel PPC Architecture: How We Structured Sponsored Products, Brands & Display

Scaling PPC to 5.8x ROAS was about building a system where every campaign has a defined role in the buyer's journey. Instead of running isolated campaigns, we designed an Amazon full funnel PPC architecture that moved shoppers from:

Discovery to consideration, conversion, and retention

 

Keyword Strategy That Unlocked Profitable Traffic at Scale

A strong strategic Amazon keyword research approach ppc was used to find high-intent Amazon keywords while focusing on "buying queries". Many sellers use Amazon listing optimization services to align their PPC campaigns for better performance and higher conversions

• Start by using Search Query performance and Brand Analytics reports to see which keywords are performing.
• Using third-party tools like Helium 10 Magnet and Helium 10 Cerebo to expand the keyword list and do a competition analysis.
• Adding seed keywords to Amazon search bar, where Amazon Autocomplete gives suggestions of long tail ppc keywords Amazon and shows real-time buyer interest.
• Use the Amazon search term report strategy to regularly identify keywords with high sales and low ACoS.
• Run automated keyword harvesting Amazon ads. This lets you identify high-converting words and finally increase ROI.

 

Bid Management & Budget Allocation Framework We Used

• Amazon PPC bid management and budget allocation were decided at the funneling stage, i.e, focused budget on proven terms.
• Weekly bid audits.
• Tight negative keywords discipline to avoid wasteful spending.
• Used automated bidding Amazon to improve efficiency.
• Dayparting Amazon ads was used to reduce spend during low-converting hours.

 

Month-by-Month Breakdown: From 2.1x to 5.8x ROAS in 90 Days

Here is a monthly breakdown of the Amazon ROAS improvement timeline:

Month	Strategies	Results
First	1. Audit 2. Restructured PPC campaign 3. Separate hero and low-performing products	Result: Stabilized ROAS.
Second	1. Shift the budget to the winners and promote them	Result: ROAS started improving.
Third	1. Expanding high-intent and long-tail keywords 2. Retargeting customers 3. Tighter Placement (waste control)	Result: ROAS scaled at 5.8x.

 

Lessons Learned: What Scaled, What Failed & What We Would Do Differently

What scaled: Consistent keyword harvesting, focusing the budget towards well-performing keywords, and separating branded and non-branded products earlier.

What failed: Expanding ad spend without tight negatives.

What we would do differently: Test sponsored brands' creatives and landing destinations sooner, and tighten negatives early.

 

Our Experience with Clients

Our Amazon PPC management experts managed $4M+ in Amazon ad spend across 60+ brands over 8 years. We personally restructured accounts that had stalled at 2x ROAS and elevated them to 5x+ within a single quarter. Surprisingly, most of them were making the same mistakes as mentioned above. Most of the clients would relax because of the early boost in sales, but it gets stagnant as more campaigns pile up.

Challenges faced
A poorly structured campaign setup was the main issue, which was split across 200+ ad groups with no negative keyword discipline, bleeding spend on irrelevant terms. Keywords were driven largely by guesswork, which increased spend with no effect on conversions.

Solutions to those challenges
The solution for that was consolidated into a 3-tier campaign architecture. We applied the best Amazon PPC strategies for 2026, ran a 14-day search-term harvest, and then implemented weekly bid audits. ROAS jumped from 2.1x to 5.8x in 12 weeks. The second step involved creating a negative keyword strategy that reduced revenue loss by 20-45%, ultimately increasing ROAS.
