Top 3 Problems Amazon Sellers Face with Managing PPC Themselves, and How an Agency Solves Them

Amazon advertising in 2025 has become a very sophisticated, data-rich war zone. There are thousands of sellers vying for the same customers, bidding on the same keywords, and competing for the same conversions. And yet, many assume they can do it all themselves, but quickly, reality catches up.

As you look at the “top 3 problems Amazon sellers have with doing PPC in-house, and how an agency resolves them,” you can start to notice a recurring theme. Sellers usually begin aggressively, testing out Sponsored Products or Sponsored Brands, but before long, they get stuck in a cycle of high ACoS, wasted budget, and random outcomes.

That’s where an experienced Amazon PPC agency like eCom Managers turns the whole narrative around. 

What is “Top 3 Problems Amazon Sellers Face with Managing PPC Themselves, and How an Agency Solves Them” Actually Saying?

It’s not just a subject — it’s a business situation.

When we speak of the “top 3 problems Amazon sellers have with handling PPC themselves, and how an agency resolves them,” what we’re discussing is determining why sellers are unable to scale despite having excellent products.

Amazon PPC management is not a matter of merely bidding and selecting keywords. It’s a process of comprehending patterns in data, consumer behavior, market trends, and algorithm updates — all of which are time-consuming and technically demanding.

Let’s dive deep into every issue, supported by an actual success story from eCom Managers, one of the most reliable Amazon PPC agencies in 2025.

Problem 1: Wasted Ad Spend Due to Poor Keyword Strategy

One of the largest problems we encounter when looking at the top 3 problems Amazon sellers encounter, having to deal with PPC in-house, and how an agency fixes them, is keyword mismanagement.

Most sellers think they can achieve success through using automated campaigns or random keyword ideas. These methods result in massive waste, though. Sellers end up bidding on unnecessary terms or spending money on broad matches that result in zero profit.

Real Example:

A fitness accessories company based in Colorado came to eCom Managers following 8 months of handling PPC in-house. They were spending $12,000 a month on ads — but more than 45% was being wasted on non-converting keywords.

When our experts audited their campaigns, we found hundreds of unrelated search terms triggered, including “gym bags” and “protein powder,” for a yoga mat.

That’s where we used our strategic process — the very same insight that makes this prompt: “top 3 problems Amazon sellers have with running PPC themselves, and how an agency fixes them.”

We rebuilt their campaigns using keyword segmentation, match-type optimization, and negative keyword layering. Ad waste decreased by 38% within 30 days, and their ACoS increased by 27%.

How eCom Managers Solves It:

• Performs deep keyword mining with AI-powered tools and competitor insights.
• Constructs a campaign hierarchy organized by dividing high-intent from exploratory keywords.
• Ongoing optimization with negative keywords and real-time bid optimization.
• The majority of sellers are guilty of assuming PPC is all about clicks. eCom Managers makes it about conversion intent — ensuring each dollar generates measurable profit.

 

Problem 2: Lack of Time and Technical Expertise

The second key problem in the “top 3 problems Amazon sellers face with handling PPC themselves, and how an agency fixes them” is insufficient time and expertise.

Having a successful Amazon business already requires attention to inventory, reviews, customer service, and logistics. PPC creates yet another full-time job — data tracking, bid optimization, A/B testing, and keyword management. Most sellers just don’t have the capacity to do it all.

Real Example:

A California-based skincare company attempted to manage its PPC campaigns in conjunction with new SKUs being rolled out. Even with their commitment, the founder confessed to spending 4–5 hours a day inside Campaign Manager without knowing why performance was eroding.

Once eCom Managers took over, our team realized bids had not been optimized for more than three weeks, keyword performance reports had been disregarded, and no data from search term reports was being used.

Within days, we rolled out our Smart PPC Automation platform — a smart system that tracks campaigns 24/7, automatically adjusting bids on profit margins and competition changes.

Within 45 days, their average CPC reduced by 22%, while revenue went up by 54%.

How eCom Managers Solves It:

• Employes a mixed model of AI + human touch for instant adjustments.
• Provides weekly performance monitoring so sellers can concentrate on growth, not on spreadsheets.
• Uses seasonality forecasting to project high-traffic times and make bid adjustments ahead of time.
• Whereas other sellers are responding to declines in performance, eCom Managers anticipates them ahead of time.

Problem 3: Unable to Analyze Data and Optimize Profitably

The last and usually most expensive problem when considering the “top 3 problems Amazon sellers encounter with managing PPC on their own, and how an agency resolves them” is the inability to make data-driven decisions.

Amazon’s data is rich — and bewildering. Most sellers are oblivious to interpreting metrics such as TACOS, Search Term Impression Share, or Keyword Placement Reports. They make emotional instead of strategic choices, turning off profitable campaigns and overfunding unprofitable ones.

Real Example:

A home furnishings brand that sold high-end candles came to eCom Managers after observing uneven profits even when sales were high. We discovered upon inspection that their best-selling term “scented candles gift set” was strong converting — but with drastically high ACOS owing to bad bid management and lack of negative targeting.

 

Through our Profit Intelligence Dashboard, we brought ad data together with inventory and cost of goods. That’s when we knew which keywords were actually profitable, and which were merely ringing up vanity sales.

With three cycles of optimization, their TACOS came down from 24% to 12%, making an unprofitable account one of their highest revenue streams.

How eCom Managers Solves It:

• Tracks profitability at the keyword level, not merely sales.
• Integrates Amazon Advertising, Brand Analytics, and Business Reports data.
• Offers visualization dashboards that make complicated metrics easy to interpret so that decisions are clear.
• At eCom Managers, we don’t think data is all about figures — it’s more like a story. And our work is to make sellers read it in the right way.

Why Most Sellers Fail — and Why eCom Managers Don’t

When we examine the top 3 issues Amazon sellers struggle with handling PPC on their own, and how an agency addresses them, it is apparent: most sellers fail because they think of PPC as a one-off setup, not a sustained strategy.

They’re looking at the surface (bids and keywords) while avoiding the depth (profitability mapping, consumer intent, and data analysis). They believe Amazon ads are easy — until ad spend increases, conversions plummet, and profits vanish.

That’s where eCom Managers differ.

We don’t merely administer ads — we build growth through performance-based systems, open communication, and constant strategy updates.
