It counts the transaction. You bank the take rate.

At a 13% take rate, a campaign reporting 6× earns 0.8× on the revenue you keep. The pixel can't tell the difference.

Your AI employee keeps the business rule: Adgent remembers take rate as confirmed context and carries it into later analyses, reports and briefs. Billing, fees and refunds enter only when you bring them.

Your take rate, unless you tell it.

The number that decides everything is the one the ad platform never holds.

Billing, fees and refunds reach Adgent only when you bring them. It doesn't reconcile marketplace sales against ad numbers.

AI Visibility doesn't support multi-brand marketplaces yet.

Running these accounts for clients? How Adgent works across a book of client accounts

Two sides to buy, and one number the pixel never holds.

Why a marketplace ad account misprices itself by default, and what the research says about where it leaks.

You have two costs of acquisition.

Take an $85 order at a 13% take rate: you keep about $11, so that is roughly what a buyer's first order is worth to you. An active seller keeps producing orders for years and can be worth many times that. One ad account, two very different values per click, and the platform reports both the same way.

Liquidity is local; budgets are not.

Below a threshold of live listings in a city, buying demand is waste however cheap the click, because the request can't be filled. The same campaign can be right in one city and wrong in the next, and averaged into one account figure both disappear. Geography breakdowns are part of what Adgent reads.

Trust can move the transaction off the platform.

A randomised trial on an online freelance marketplace found that once trust between the two sides was high enough, more of them took the work off the platform, offsetting the revenue gained from better matches. A match your ads paid for is not always a transaction you bill.

Bidding against your own supply.

When eBay switched off brand-keyword search ads in a controlled test, the traffic came back through its own organic results; the paid clicks had bought little it wasn't already getting. Marketplaces routinely buy branded and category terms their own listings already win.

The questions marketplace teams ask first.

Why does our ROAS look strong when the business barely breaks even?
Check what your conversion value is passing first. Most marketplace accounts send gross transaction value, so the reported return is the real one divided by your take rate. At 13%, a reported 6× is roughly 0.8× on the revenue you keep. Changing the field takes a minute; the bidding then needs time to unlearn what it was bidding against. Ground truth
Can it show me which listings sell, or only campaign totals?
Lower than campaign totals. Each account is read bottom-up, ad, ad set, campaign, account, with breakdowns by geography, placement, device and demographic, so a campaign that is fine on average but failing in half its cities shows up. Where you run Shopping, the Merchant Center catalogue and item issues can be read too, read-only. Listing-level margin still lives in your own systems.
How do I stop budget flowing to what only looks profitable?
Fix what the account counts before you move money. The Trust Gate labels each metric window before it is scored, and a window it cannot trust can raise a finding, never an action. Each account move then keeps its evidence, before-state and later result in the Change Ledger. Trust Gate
What can't it see about my marketplace today?
Your take rate, unless you tell it. Net revenue, take rate by category and acquisition cost per side sit in your backend or warehouse, and Adgent doesn't read them. Seller-account connections for marketplaces such as Trendyol and Hepsiburada are a low-priority roadmap item, pulled forward only by demand. Today it reads Meta and Google Ads, with GA4, Search Console and Merchant Center.

Tell Adgent the take rate once. It keeps that business rule beside the ad account and carries it into the next report and account move.
