Amazon shows exactly what you spend on each product for Sponsored Products ads. Brand ads, like Sponsored Brands and Brand Video, promote your brand, so Amazon doesn't break the cost down by product.
ConnectBooks still splits that cost across your products, so your P&L shows ad spend per item.
How the split works
When you set up a brand ad, you pick the products it features (Amazon calls these the creative ASINs). Usually it's 1 to 3.
ConnectBooks finds every active SKU for those ASINs.
It splits the ad cost evenly across those SKUs. Clicks are split the same way.
Example: an ad costs $90 and features 2 ASINs. ASIN A has 2 active SKUs and ASIN B has 1. Each of the 3 SKUs gets $30.
Only SKUs whose listing is active get a share. Inactive listings don't pick up ad spend.
If none of the featured products has an active SKU, the cost stays as 1 line for the campaign, not split by item.
Frequently asked questions
Why does an ASIN with more SKUs get more of the cost?
The split is per SKU, not per ASIN. An ASIN with 2 active SKUs gets 2 shares.
Some brand ad spend isn't tied to any item. Why?
None of the ad's featured products had an active SKU, so the cost stays at the campaign level.
Does this change Sponsored Products ads?
No. Those already come from Amazon per product.
