When entering the digital marketing ecosystem, the ability to precisely target your ideal customer is a necessity. If you are advertising on Amazon, leveraging AMC for Custom Audiences can significantly boost your campaign's efficiency, relevance, and ROAS. With platforms like Hector, advertisers and sellers can turn AMC's raw data into scalable strategies.
However, before diving into leveraging Hector to unlock AMC's full potential, let's first understand what AMC Custom Audiences are, why they matter, and how you can create them.
What is an AMC Custom Audience?
An AMC Custom Audience is a user-defined group of Amazon customers/shoppers built using insights from the Amazon Marketing Cloud, SQL-based analytics, and Amazon's privacy-safe. Unlike standard DSP segments, these audiences are created by analyzing customer behavior signals such as:
Add-to-cart actions
Product views
Purchase patterns
Search term history
Ad interactions across Sponsored Ads and DSP
The custom segmentation gives brands the power to define audiences based on real engagement, not guesswork. You may think of it as building hyper-targeted segments from scratch using verified, Amazon native behavioral data.
Why Are AMC Custom Audiences Important?
Standard audience targeting often relies on a pre-set criterion that may or may not align perfectly with your goals. AMC Custom Audiences let you move beyond broad strokes to build segments that directly reflect how customers interact with your products and ads. The Custom Audience approach leads to:
Higher Campaign Relevance: You are speaking to users at the right stage in their buying journey.
Improved ROAS: Better targeting means less waste and more conversions.
Data-Driven Scaling: Use purchase frequency, keyword behavior, or demographics to expand new audiences.
Stronger Personalization: Customize your message to different user intents, whether they are just browsing or ready to buy.
Custom audiences are not only effective but also smarter. And platforms like Hector make building them faster, easier, and more strategically.
How to Create AMC Custom Audiences on Amazon
Creating AMC Custom Audiences requires:
Access to Amazon Marketing Cloud: You need to be whitelisted or have access through a partner or AMC-enabled platform.
Understanding Your Audience Goals: Start by selecting the behavior you are targeting. It could be anything, such as past purchasers, recent viewers, cart abandoners, or even customers who searched for specific keywords.
Writing SQL Queries: AMC operates in a SQL environment. You would need to write queries to extract the audience segments you want. However, with Hector (an AdTech platform), no SQL is required to create a custom audience, eliminating manual work and time.
Export and Activation: Once your audience is defined and validated, it can be exported into Amazon DSP or Sponsored Ads for activation
The traditional SQL Query writing process is quite time-consuming; that's where Hector changes the entire game.
Simplifying Custom Audience Creation with Hector
While AMC offers a plethora of insights, extracting value from it can be challenging without the right technical expertise. We bridge that gap by making custom audience creation goal-oriented and intuitive.
Using our platform, advertisers can:
Build lookalike audiences of high-value shoppers to expand reach
Segment by search behavior, device usage, and location
Create add-to-cart audiences to retarget non-converting users
Focus on repeat buyers for retention
These audience strategies can be activated directly in Amazon Ads with minimal effort. This can be achieved by maintaining the integrity and customization AMC enables.
Learn the Best Practices for AMC Custom Audience
Whether you are using AMC directly or through our platform, follow these practices to ensure maximum impact:
1. Use Time Window Segmentation
Differentiate audiences based on recent vs. past activity, such as those who purchased within 7 days vs. 60 days.
2. Combine Data Sources
Use a mix of Amazon retail signals and ad engagement data. The more dimensions your audience has, the better your targeting becomes.
3. Leverage Audience Overlap Tools
It is crucial to understand how different audiences intersect. This is essential for cross-selling and avoiding wasted impressions.
4. Exclude Irrelevant Users
Don't waste the budget on users who've already converted. Carefully choosing who to exclude is as important as picking whom to include.
5. Apply RFM Segmentation
Segment the customers by Recency, Frequency, and Monetary value to determine the one-time buyers.
