Solutions/Ads optimization
E-commerce ads optimization for Shopee, Lazada, and TikTok Shop, on profit
E-commerce ads optimization usually means letting the platform optimize. Marketplace ad systems are tuned for GMV (hence the name GMV MAX), not your true profit. This can lead to unprofitable decisions and lost margin. DataGlass models True ROAS per campaign, flags the spend that is not paying back, and surfaces the budget moves that grow profit.
01/Problem
What sellers see
The platform dashboard shows a clean, high 4.0 ROAS and a green ACOS. However, the bank account tells a different story. E-commerce platforms make money from taking commission on revenue. Their incentive is to maximize order volume, not your profit. They do not know your COGS, your fees, or your margin. The more ads they show, the more volume there is, and the more money they make. You, on the other hand, are wasting money on ads when they are no longer profitable. The platform also shows raw ROAS — which includes canceled orders, duplicated attributions, and fees that should have been deducted. That inflates the number the seller sees, leading them to believe it is a high return.
- Platform ROAS looks healthy but profit is flat or shrinking
- Broad-match keywords spending budget that never converts on a profitable SKU
- Top-spend campaigns with hidden negative True ROAS
- Budget is fully consumed by 11am every campaign day with no margin to show for it
- Running Shopee Ads? Shopee Ads optimization: budgets and Target ROAS set from profit
- Running TikTok Shop GMV Max? TikTok Shop ads optimization on profit
- Counting on ROAS protection? It only protects profit above 1.25× break-even
02/Detection
What DataGlass detects
DataGlass reconstructs every ad-attributed order down to the SKU, deducts COGS, marketplace fees, vouchers, and fulfillment, and shows True ROAS per campaign. This is the very first layer of our decision making process: having clean data to make decisions on. Moreover, dataglass also compute the full unit profit breakdown of all skus, allowing us to work directly on profit not revenue. This is a very important distinction as your revenue can grow while profit shrinks.
- Campaigns with True ROAS below break-even after full cost
- Keywords pulling traffic but converting on low-margin SKUs only
- Ad groups where Shopee or Lazada keyword expansion has bled margin
- Daily budget pacing — over-spend before the profitable hours of the day
03/Action
Recommended actions
We take the above cleaned signal data and build a mathematical model to predict tomorrow's latent demand. By this construction, we optimize tomorrow's budget cap to maximize profit. We also account for downside risks, since the e-commerce marketplace landscape is uncertain and shifting. Risk is baked directly into the optimization to protect against losses on a bad day, giving stable long-run profit-maximizing performance.
- 01
Shift budget to profitable campaigns
Re-allocate spend from campaigns with negative contribution to those with the highest expected lift.
- 02
Adjust bids to break-even ACOS
Set bids that respect the SKU's break-even ACOS, not the platform's suggested target.
- 03
Restructure aggressive expansions
Tighten match types and negative-keyword lists where the platform's expansion is the source of the waste.

Prediction and Risk Optimization Under Uncertainty: A Cross-Domain Meta-Review of Methods in Finance, Operations, Causal Inference, and E-Commerce Decision Intelligence
A structured meta-review (213 primary works, 254 references) arguing that mature decision systems across finance, operations, insurance, energy, healthcare, causal inference, and e-commerce share four primitives — calibrated probabilistic models, coherent risk-aware objectives, explicit operational constraint sets, and principled exploration. Eleven worked cases ground the framework, with the DataGlass marketplace ad-budget system as the connecting tissue.

04/FAQ
Frequently asked
Platform dashboards show attributed revenue. DataGlass shows profit after fees, COGS, vouchers, and fulfillment — the actual number that determines whether the campaign was worth running.
Yes, for the campaigns you put in an optimization group. On Shopee and on TikTok Shop GMV Max, DataGlass sets each campaign’s budget every night from expected profit, steps budgets through the day through each platform’s official API, and proposes a margin-based Target ROAS you apply in one click. Every change is logged with its reason, and you can pause a group or switch a shop to read-only at any time.
Profit-aware bid adjustments target campaigns and keywords that are losing money, not the ones driving organic ranking. DataGlass shows the trade-off explicitly so the decision is informed.
