Whether to use Targeting Expansion in Amazon Ads depends on your product type and goals. Here's a breakdown to help you decide:
For Broad Products (e.g., water bottles, yoga mats, phone chargers):
YES — Use Targeting Expansion
Why:
Broad products have mass appeal, so expanded targeting helps you reach untapped audiences you may not have manually considered.
Amazon’s algorithm may discover high-converting adjacent queries or ASINs you didn’t target.
It can help scale impressions and sales quickly, especially for Sponsored Products and Sponsored Display campaigns.
Best Use Case:
When launching a new product to scale visibility fast
When testing new markets or audiences
If your current manual targeting is saturated or plateauing
For Niche Products (e.g., custom 3D printer nozzles, vegan protein for seniors):
CAUTION — Use Targeting Expansion Sparingly
Why:
Amazon may expand too broadly, showing your ads to irrelevant shoppers, leading to:
You lose control over who sees your ads, which is risky if you need laser-focused targeting.
Best Use Case (If at all):
After strong baseline performance with manual targeting
When testing expansion in a separate, low-budget campaign
If you have budget to experiment and monitor results closely
Pro Tip:
Always test Targeting Expansion in a separate campaign, so it doesn’t mess with your main ad performance data. Watch for:
