Amazon DSP often starts the sale, but you won’t see it in last-click ROAS. And just as often, it restarts a sale that didn’t finish.
Amazon DSP is built for audience-based, programmatic advertising. It reaches shoppers before they search. And after they stop searching.
This becomes clear once you look at conversion paths.
These are real numbers from one of our clients’ accounts.
In the DSP console, direct DSP-attributed sales are ~ $590K, with ROAS 8.68, which is a solid performance. But conversion paths show what last-click reporting misses.
~$697K in sales come from paths where DSP appears after Sponsored Products and plays a key role before the purchase.
~$688K in sales come from paths where DSP is the only paid touchpoint before checkout.
~$460K in sales start or restart with DSP before Sponsored Products closes the loop and gets the attribution.
Some sales start with DSP, some start organically or through Sponsored Ads, but not all of them finish. Shoppers view a listing, click an ad, compare options, then leave.
This is where DSP fills the gaps.
DSP retargets shoppers who already showed intent but dropped out of the journey.
It reconnects with them after the initial interaction, not during the search. Sponsored Ads capture demand in the moment. DSP brings it back later, when timing and attention change.
This is DSP’s real role in the funnel.
Even with the full Sponsored Ads setup active, gaps remain in the customer journey. DSP helps close them. AMC audiences in the advertising console boost visibility. However, DSP is still essential for mature products, not new launches.
If you run DSP in isolation, you will undervalue it. If you evaluate it as a funnel connector, the strategy changes.
