Audience targeting on Amazon got classified as a display tactic years ago, and nobody went back to check.
AMC can tell high-value shoppers apart from one-time buyers. For most advertisers, that capability only ever reached DSP, which is the smaller half of their spend. So Nectar launched Customer Atlas last month to point it at the larger half: Sponsored Products and Sponsored Brands.
It indexes up to five years of a brand’s Amazon purchase history against all 6,728 audience segments Amazon exposes. Two lists come back. Segments that concentrate among high-value buyers. Segments that concentrate among people who buy once and never return.
Activation is standard AMC audiences in DSP and audience bid modifiers in Sponsored Products and Sponsored Brands. In search, that means a low base bid with a boost applied only when a targeted shopper searches. No new campaigns, no new budget.
The method was built to move CVR, LTV, and CPA. Those were the metrics we pre-registered against.
First live deployment moved all three, and CPC came down a third against the same brand’s standard campaigns. The CPC drop was not what we were solving for.
What the method surfaces is routinely the opposite of what a category plan assumes. In one engagement, the largest audience segment in the category reached 24.9M shoppers and had no relationship at all to repeat purchase, while far smaller segments predicted it strongly.
That gap is what Customer Atlas was built to close. It now shapes how we bid in search for every brand we run. Full coverage in Yahoo Finance below. Happy to walk through the method on your own category.
