If you’re an Amazon seller struggling with high ACoS and low ad performance, your keyword strategy might be to blame. The solution? Long-tail keywords.
In this guide, you’ll learn how to use long-tail keywords for Amazon PPC to:
- Improve ad targeting
- Reduce wasted ad spend
- Lower ACoS
- Boost conversion rates
- Drive higher ROI
What Are Long-Tail Keywords in Amazon Advertising?
Long-tail keywords are highly specific search phrases, usually containing three or more words. These keywords reflect clear buyer intent and often result in higher conversion rates compared to broad or short-tail keywords.
Examples of Long-Tail Keywords:
- “organic baby lotion for sensitive skin”
- “wireless earbuds for small ears noise cancelling”
- “glass coffee mugs set with handles microwave safe”
These phrases are less competitive, more targeted, and better aligned with buyer search behavior.
Why Long-Tail Keywords Are Critical for Amazon PPC Success
When using Amazon Ads (sponsored products or sponsored brands), bidding on generic keywords can drain your budget fast. Here’s why long-tail keywords give you a competitive advantage:
Benefits of Long-Tail Keywords:
- Lower CPC (Cost Per Click) due to reduced competition
- Higher relevance score, leading to better ad placements
- Improved CTR (Click-Through Rate) and conversion rate
- Lower ACoS by focusing on buyer-ready search terms
Targeting high-intent keywords helps Amazon’s algorithm understand your product’s relevance, improving your ad rank and campaign performance.
How Long-Tail Keywords Lower ACoS on Amazon
ACoS (Advertising Cost of Sales) is a key performance metric for Amazon sellers. A high ACoS means you’re spending too much to make a sale and help reduce ACoS by:
- Reaching users closer to the buying decision
- Minimizing irrelevant clicks
- Driving more efficient ad spend
Example:
Selling “portable pet water bottles”? Instead of bidding on “dog water bottle,” use:
- “collapsible dog water bottle for hiking”
- “leak-proof travel water bottle for dogs 20oz”
These keywords not only attract the right audience but also reduce competition and increase conversion probability.
SEO Strategy for Finding Long-Tail Keywords for Amazon PPC
Want to find long-tail keywords that rank and convert? Follow this step-by-step strategy:
1. Use Amazon Auto-Suggest
Start typing your main product keyword and let Amazon’s search bar show relevant long-tail suggestions. These are actual customer queries.
2. Analyze Search Term Reports
In Amazon Seller Central, review your search term reports. Look for 3-6 word phrases that generated sales with a low ACoS.
3. Use Keyword Tools with Long-Tail Focus
Try tools like:
- Helium 10 (Cerebro, Magnet)
- Jungle Scout
- Ahrefs or Ubersuggest (for external traffic ideas)
4. Focus on Intent Modifiers
Add qualifiers like:
- “best,” “top-rated,” “for [use case]”
- “under $25,” “2025,” “with [feature]”
These modifiers make your keywords more specific and better matched to purchase intent.
