Question 1

What does ACOS mean for Amazon Merch sellers?

Accepted Answer

ACOS means aggregate advertising cost of sales. Calculate it as aggregate Amazon Ads spend ÷ Amazon Ads-attributed sales × 100. A 28% ACOS means €28 was spent for every €100 in sales Amazon attributed to those ads. Ads-attributed sales are not the same as Amazon royalties.

Question 2

What is a good ACOS for Amazon Merch?

Accepted Answer

There is no single good ACOS for every catalog. A useful target depends on royalties, price, conversion rate, and your advertising goal. Merch HQ helps you compare aggregate advertising cost of sales and spend with Ads-attributed sales and Amazon royalties rather than treating ACOS as a product-margin calculation.

Question 3

Can ACOS be low while the overall result is still weak?

Accepted Answer

Yes. ACOS only compares aggregate Amazon Ads spend with Ads-attributed sales. A low ACOS does not account for royalties or general accounting costs, and Merch HQ does not calculate product margins. Its narrow aggregate measure, Royalties after ads, is Amazon royalties minus aggregate Amazon Ads spend for the selected period.

Question 4

How does Merch HQ display ad spend?

Accepted Answer

Current production displays aggregate Amazon Ads metrics. Ads data depends on an authenticated Amazon Ads session in the browser; it is not a product-level or campaign-attributed Merch view. Amazon royalties are shown separately from Ads-attributed sales.

Question 5

Can I compare ACOS with Amazon royalties?

Accepted Answer

Yes, but keep the measures distinct. Amazon Ads-attributed sales are sales Amazon associates with ads, while Amazon royalties are the estimated payout, normalized to USD. Royalties after ads means Amazon royalties − aggregate Amazon Ads spend for the selected period; it is not a complete business result or product margin.

Question 6

What does 'Royalties after ads' mean?

Accepted Answer

It is a selected-period calculation: Amazon royalties − aggregate Amazon Ads spend. It is a narrow business-level measure, not a complete business result, a product-level margin, or a calculation that includes product costs and other expenses.

Question 7

Can I see advertising spend by product or campaign?

Accepted Answer

No. Current production displays aggregate Ads metrics; product and campaign attribution is not shipped.

Question 8

How many campaigns does the current Ads view include?

Accepted Answer

The current Ads view is limited to the first 200 campaigns returned by the report and does not paginate beyond those campaigns.

Question 9

How are daily Ads metrics calculated?

Accepted Answer

Daily Ads values may be reconstructed or allocated from report totals. Treat the daily breakdown as an allocation of aggregate data, not as direct product- or campaign-level spend attribution.

Question 10

Does Merch HQ automatically change my campaigns?

Accepted Answer

No. Merch HQ is designed to help you understand your numbers. It does not automatically change campaigns or make advertising decisions for you.

Question 11

How often is advertising data updated?

Accepted Answer

Merch HQ uses on-demand and cache-scheduled updates. The current implementation schedules an Ads alarm every three hours. Cached data is treated as stale after two hours, and a manual sync can request an update when an authenticated session is available. Actual availability also depends on Amazon and session state.

Question 12

Which Amazon Ads marketplaces are supported?

Accepted Answer

Current Amazon Ads support covers six marketplaces: US, UK, Germany, France, Italy, and Spain. Ads marketplace coverage is separate from Merch net-unit support, which may have different coverage.
