An ACoS of 89% means an Amazon seller is spending $89 in advertising for every $100 generated through those ads. That level of spend can erase margins quickly, but the advertising account is not always the real cause. An Ecommerce Growth Service should first examine the listing, search terms, conversion rate, product margins, inventory position, and campaign structure before simply lowering bids.
Our team has seen sellers react to high ACoS by cutting budgets immediately. That can reduce spend, but it can also remove profitable traffic and slow sales. A better assessment starts with the complete customer journey. If shoppers click an advertisement and leave without buying, reducing bids does not fix the conversion problem. The seller needs to understand why those shoppers are not converting in the first place.
Product relevance is another important factor. A campaign can generate plenty of clicks while still producing weak results if the advertised product does not closely match the shopper’s search intent. Search-term reports can help identify whether the traffic is coming from relevant queries or from terms that attract clicks without meaningful purchase activity.
A home and kitchen seller we reviewed had an 89% ACoS across several campaigns. The account contained broad targeting, duplicated search terms, weak secondary images, and products with very different profit margins grouped under similar campaign structures. The advertising manager was treating every SKU in the same way.
That approach made it difficult to determine which products deserved additional investment and which products needed a different strategy. Some SKUs were generating sales but had limited margins, while others had better margins but were not receiving enough relevant traffic. Looking only at ACoS did not provide enough information to make those distinctions.
We separated products by commercial role, reviewed search-term performance, and connected advertising decisions with listing performance. The team also reviewed customer feedback because repeated questions often showed where the product page lacked useful information. When customers repeatedly ask about dimensions, materials, compatibility, or product use, those questions can indicate areas where the listing needs clearer content.
The product detail page was also reviewed from the shopper’s perspective. Images, titles, bullet points, descriptions, pricing, reviews, and the overall presentation all influence what happens after an advertisement receives a click. Advertising can bring visitors to the listing, but the listing still has to give those visitors enough confidence to purchase.
Another part of the review involved campaign structure. Different products may require different budgets, targeting methods, and performance expectations. Separating branded, non-branded, category, competitor, and discovery-focused campaigns can make it easier to understand where advertising money is going and what each campaign is expected to accomplish.
Sellers also need to consider inventory before increasing advertising spend. A product with limited stock may not need aggressive promotion, while a well-stocked product with strong conversion potential may be able to support additional traffic. Advertising decisions should therefore be connected to inventory planning rather than managed independently.
Sellers needing this type of account-wide work can consider a full service ecommerce agency. The value comes from looking at the different parts of the Amazon operation together instead of treating PPC as an isolated activity. Advertising performance, listing quality, organic visibility, inventory, pricing, and customer behavior can all affect the final result.
After the changes, spending became more controlled because campaigns had clearer purposes. The team could identify which search terms were worth pursuing, which products required listing improvements, and where advertising spend was not producing enough commercial value. This created a more structured way to manage the account instead of reacting to ACoS changes from week to week.
The lesson was simple: high ACoS can be a symptom of several connected problems rather than a bidding problem alone. Sellers should look beyond one advertising metric and evaluate how paid traffic interacts with the rest of the customer journey.

Strong organic performance can complement advertising by helping products reach shoppers through unpaid search results while paid campaigns focus on specific commercial opportunities.
For Amazon sellers, the goal should not simply be to achieve a lower ACoS at any cost. A lower advertising percentage is only useful when it supports profitable sales and sustainable account growth. The right analysis considers revenue, profit margins, conversion rates, traffic quality, customer demand, and the role each campaign plays in the wider business.
