How does Nova bring in your Amazon DSP data?
Nova finds your DSP advertisers through the Amazon Ads connection you already made, links each one to your seller account, and reads eight DSP reports every day. DSP cost appears in the P&L under Advertising cost, in TACOS and in Net profit, and stays out of PPC spend, ACOS and ROAS.

How does Nova link a DSP advertiser to your account?
Every advertiser your Ads login can see is checked against your seller account. The first rule that matches wins:
| # | Rule |
|---|---|
| 1 | A link set by the Nova team, on request |
| 2 | Amazon's own link between the advertiser and your Ads profile |
| 3 | At least 80% of the advertiser's promoted ASINs are yours |
| 4 | The advertiser's name matches your account |
An advertiser that matches no rule is not shown.
Which reports does Nova read?
Line items, products, supply source, device, creative, audience, country and the order summary. They give promoted and total sales, ROAS and total ROAS, new-to-brand, viewability, eCPM, detail page views, add to cart, and reach and frequency by order.
Line items refresh daily, and the last 15 days are re-read every day. History goes back about 95 days, as far as Amazon keeps it.
Where does DSP cost land?
| Metric | DSP included |
|---|---|
| Advertising cost, P&L | Yes, on its own "Amazon DSP" line |
| TACOS, Net profit | Yes |
| PPC spend, ACOS, ROAS | No |
DSP cost is shared across ASINs in proportion to their promoted sales. Amazon does not report DSP cost per ASIN, so Nova shows no per-ASIN DSP ROAS.
What is not covered yet?
DSP cost in the Vendor Central (1P) P&L, and agencies that run DSP without the brand's Ads login.
