Introduction
Grow High-Intent Lookalikes templates help you scale prospecting by finding new shoppers who resemble your strongest existing audiences. By using high-intent behaviors (purchases, cart adds, or loyal subscriptions) as a "seed," Amazon’s algorithm identifies unexposed shoppers with a similar profile.
These templates allow you to expand your reach beyond retargeting pools without starting from scratch, ensuring that your acquisition efforts remain anchored to proven shopper personas.
Who needs this
-
Saturating Current Pools: Use these templates when your retargeting and standard "In-Market" audiences have hit a reach ceiling.
-
Finding "High-LTV" Prospects: Ideal for finding net-new shoppers who are likely to become long-term loyalists rather than one-time buyers.
-
Category Expansion: Use your brand persona to find similar shoppers in adjacent categories.
-
Rapid Scaling: Quickly launch expansion audiences without needing deep AMC/DSP audience-building experience.
Template Guide: Goals & Strategic Setup
| Audience Template | Goal | Best practice | Tips |
|---|---|---|---|
Purchase Lookalike |
Reach shoppers similar to your converters. | Start with Most Similar. Use a 30–180 day seed window for stable volume. | Best for high-quality prospecting. Lead with hero products and optimize for DPV/Reach early on. |
Add to Cart Lookalike |
Target users who behave like high-intent shoppers. | Use a 7–30 day seed window (stronger intent). Start Most Similar / Similar. | Use offer-led creatives (coupons, bundles) to nudge these high-intent lookalikes toward their first purchase. |
New to Brand Lookalike |
Drive NTB expansion via similar profiles. | Use 30–90 day seed window to reflect current acquisition. Start with Most Similar. | Use "Switch" creatives (comparisons/differentiators) and measure Brand Search Lift as a success signal. |
Loyal Shoppers Lookalikes |
Find high-LTV / Premium prospects. | Keep Most Similar longer before broadening; this template is about quality over volume. | Use Brand Story messaging. Expect longer consideration windows but higher long-term value. |
Core Keyword Lookalike |
Expand reach based on top-converting search terms. | Use a focused seed set tied to your best converting keywords; start Most Similar. |
