Marketplace ads management that decides per product, against margin

ACoS vs TACoS: which number should run your account

ACoS divides ad spend by the sales those ads produced; it tells you whether a campaign pays for itself in isolation. TACoS divides ad spend by total sales, organic included, so it shows how much of the whole business is being bought.

Neither number knows your margin. Amazon's own ACOS guide also works out a good ACOS from profit margin and break-even. That is why we read ad share of revenue next to per-product profit.

• A falling TACoS while ad sales hold steady usually means organic sales are growing alongside the ads.
• A rising TACoS with flat total sales means you are paying for orders you might have had anyway.
• The highest cost per click a product can carry is its margin per sale times its conversion rate; above that, ad sales lose money.

What marketplace ads management covers

Work starts with product selection and moves to ad decisions: lower bids or pause where ad share is high and margin is thin, add budget where margin holds.

• The margin impact of a price change is calculated before you change it.
• If you need ad images for many products at once, the catalog ads screen produces them; each image uses credits.
• The product catalog scores each product on readiness and price position.

Marketplace ads management in five steps

Product sets are recalculated each time you open them. When order data is missing, the set says so instead of showing zero products, because a missing connection and a weak catalog need different fixes.

Review cadence follows your tier: weekly at Starter, every two days at Growth, daily at Scale. The monthly report is built on our reporting engine.

Product ads, store ads and your listing

Marketplace ads come in two broad forms: ads that push a single product and ads that promote a brand or store. They are measured differently.

Amazon describes Sponsored Products as cost-per-click ads that promote individual product listings, with bids and budgets set by the advertiser. We do not connect to Amazon Ads, so Amazon campaigns are not managed in this service today; the definitions are here because ACoS comes from Amazon's own vocabulary.

An ad buys the click; the listing decides the sale. Weak images, a vague title or a price above the category range lower conversion, and every lost conversion makes each click more expensive. If no category median is recorded, price competition is left out of the score rather than estimated.

Where the profit figures come from

Profit is calculated from five items. On Trendyol, where the fee-level breakdown runs today, each one has a clear source:

Why a strong return on ad spend can still hide a loss is covered in high ROAS, no profit.

Which marketplaces work today, by region

We tell you before you buy which marketplace works in which region and what the panel reads there. This is where things stand:

Selling in Germany, Belgium, the Netherlands, the UK or the US? The setup that works today is your own Shopify store, with search and Shopping campaigns under Google Ads management and Facebook and Instagram campaigns under Meta ads management. European marketplaces stay outside this service until a connection exists.

Your catalog can come from the accounts above or from a Shopify or WooCommerce store; store management explains how connected channels are run together. On Trendyol, the buybox tracker shows your position, the winning price and whether other sellers are on the listing.

Marketplace ads management pricing by tier

The management fee follows your monthly ad spend tier. Ad spend is paid to the marketplace from your own seller account and is not part of these figures.

• Included: per-product ad decisions, buybox tracking (Trendyol), ad share and margin reading, catalog checks, price position tracking, monthly report.
• Not included: ad spend paid to the marketplace, credits used to produce catalog images, store operations.

Software, in-house or agency: an honest comparison

Bid software is cheap and fast at repetitive changes, but it optimizes the target you give it. An in-house specialist knows your catalog deeply and costs a salary whatever your spend. A marketplace advertising agency brings people across many accounts; ask who actually works on yours. If most of your sales are on Amazon, a specialist Amazon agency fits better today, because we do not connect to Amazon Ads.

We sit between software and an agency: rules and screens do the repetitive reading, a person makes the per-product decision, and the fee is published. If your costs are not recorded yet, recording them helps more than any of the three. To send traffic from outside the marketplace, combine it with Meta ads management.
