Different products, shared campaigns
SKUs with different prices, margins and sales velocity were grouped together, making meaningful budget control difficult.
TACoS from 18% to 11%. Net profit up 22%.
The budget was moving. The business couldn’t see what it was buying.

A busy ad account. A blurred picture.
More than 60 products were competing for budget inside a mixed campaign structure. The account was spending, but the client could not clearly see which products the spend supported — or at what real cost.
Our initial audit uncovered four connected problems. Together, they made account-level performance a poor guide to what was happening inside the catalog.
Popular products absorbed the budget
Low-margin bestsellers took a disproportionate share of spend while higher-margin products received too few clicks.
ROAS without the cost context
Return targets were not anchored to each product’s break-even point. An attractive revenue return could still conceal weak or negative profitability.
Advertising ahead of inventory
Low-stock products continued receiving strong advertising support, increasing the risk of stockouts and lost organic momentum.
An account average can hide 60 different realities.
Every SKU has its own cost structure, margin and stock position. To regain control, advertising decisions had to follow those differences.
One catalog. Three useful lenses.
We rebuilt the account into manageable clusters using margin, price band and stock cover. Each lens informed where budget could work harder — and where it needed restraint.
Margin
What can this product afford?
Separate products by their ability to support advertising costs, so popularity alone does not decide where the budget goes.
Prioritize
Higher-margin products
Dedicated campaigns with more room for competitive bids, within product-specific economic limits.
Constrain
Lower-margin products
Stricter cost control, with less tolerance for expensive clicks that consume the remaining margin.
Price band
Are these products comparable?
Keep inexpensive accessories and higher-priced kitchen equipment in separate campaign groups with appropriate bidding limits.
Separate
Everyday accessories
Smaller-ticket products managed in their own groups, using the economics of those products.
Differentiate
Higher-ticket equipment
A distinct bidding framework, without mixing different selling prices into the same campaign logic.
Stock cover
Can inventory support demand?
Adjust budgets to the available stock and its rate of sale. In this account, more than 60 days of cover was a criterion for scaling priority.
Scale selectively
Inventory available
Scaling comes first when stock is ample and the product’s economics support the additional spend.
Protect stock
Inventory constrained
Lower advertising limits, preserving position while replenishment catches up.
A limit for every bid. A reason for every limit.
We moved from generic bidding recommendations to limits informed by each SKU’s actual cost structure and break-even ACoS.
Real cost of sale
The costs and margin of each individual SKU.
Break-even ACoS
How much advertising the product can support before its contribution is exhausted.
Bid ceiling
A product-specific limit on keyword and targeting bids.
No bid goes beyond what the product’s economics can justify.
Don’t accelerate demand past available supply.
Stock cover became part of the advertising decision, alongside margin and price.
Products with ample inventory could receive more support. Products approaching a stockout received lower limits, helping the business protect continuity instead of pushing every SKU at the same intensity.
Time to conserveUntil supply catches up
Room to scaleWhen margin supports it
The 60-day line was drawn for this catalog, not as a rule for every account.
Lower advertising burden. Higher net profit.
TACoS fell from 18% to 11% while net profit grew by 22%, and spend across the catalog came under clear control.
TACoS
Advertising spend as a share of total sales, down 7 percentage points.
Net profit
+22%
Growth in net profit, while advertising took a smaller share of sales.
SKU-level visibility
The client could see where the advertising budget was going and understand the economics of the products it supported.
Healthier ACoS and TACoS
Spend shifted away from uneconomic clicks toward products that could make a stronger contribution to profit.
Stock-aware advertising
Advertising intensity became aligned with inventory, reducing exposure to avoidable stockouts and the disruption they create.
Start with the math. Then buy the click.
For a broad catalog, effective PPC starts with product economics. Connect bids to margin and budgets to inventory, and growth becomes a decision the business can understand.
