DSP Metrics Explained: DPV, Add to Cart, NTB Purchases and CPA

Every Amazon DSP screen in TrackIQ — Campaigns, Ad Groups, Creatives, Audience, Products, Technology, Geography and Inventory — carries the same column set. Several of those columns exist nowhere else in the product, because DSP is measured differently from Sponsored Ads.

The DSP campaigns screen

The familiar columns

Ad Sales, Spend, Impressions, Clicks, ACoS, ROAS, CTR, CPC and Orders mean exactly what they mean on the Sponsored Ads screens.

The DSP-only columns

Column What it counts
DPV Detail page views driven by the ad — people who went and looked at the product.
Add to Cart Cart additions driven by the ad.
NTB Purchase Clicks Clicks that ended in a purchase by a shopper new to your brand.
NTB Purchases Purchases by shoppers new to your brand.
CPA Cost per acquisition.
CVR Conversion rate. The Sponsored Ads screens call the same metric CR.

Why DSP should not be judged on ROAS alone

The DSP conversion funnel

Sponsored Products meets demand that already exists: someone searches, you appear, they buy. DSP mostly does the opposite — it puts your product in front of people who were not looking for it.

That changes what good looks like. A DSP campaign that generates a large number of detail page views and cart adds is working, even when the ROAS on the same row looks poor against a Sponsored Products campaign. The purchase often happens later, through a different route, and gets credited elsewhere.

So read the funnel across, not just the last column:

  1. Impressions → did it reach people?
  2. DPV → did enough of them care to look?
  3. Add to Cart → did the listing convince them?
  4. NTB Purchases → did it bring in people you did not already have?

A campaign that drops off sharply between DPV and Add to Cart has a listing problem, not a targeting problem. One that reaches plenty of people but generates few detail page views has the reverse.

NTB is the number that justifies the channel

If DSP is doing the job it exists for, its NTB Purchases should be a high proportion of its purchases — higher than your Sponsored Products campaigns manage. That is the case for running it: it buys customers rather than orders.

To see that comparison properly, the AMC Cloud dashboards break new-to-brand performance down across every channel at once.

The eight DSP screens

Each one applies the same columns to a different dimension:

Screen Groups performance by
Campaigns campaign
Ad Groups ad group
Creatives individual creative
Audience audience segment
Products product
Technology device
Geography location
Inventory where the ad ran
