Overview

Keyword research is the process of discovering the exact words shoppers type into Amazon when looking for products like yours. It directly impacts your product visibility, advertising costs, and sales velocity.

In this guide, you’ll learn how Amazon uses keywords, how to find the right ones, and how to apply them to listings and PPC campaigns for measurable growth.

Who This Is For

This article is for:

  • 🟢 New sellers who don’t understand why their product isn’t showing in search results

  • 🟢 Sellers launching a new product

  • 🟡 Private label brands optimizing existing listings

  • 🔵 Advanced sellers looking to reduce PPC waste and improve organic ranking

Key Concepts You Need to Know

Before diving in, understand these Amazon-specific terms:

🔎 Keyword

A word or phrase customers type into Amazon search (e.g., “stainless steel water bottle 32 oz”).

🏷️ Search Term

Backend keywords added in Seller Central → Inventory → Manage All Inventory → Edit → Product Details → Generic Keywords.

📈 Organic Ranking

Your product’s position in unpaid Amazon search results.

💰 PPC (Pay-Per-Click)

Amazon Ads campaigns where you bid on keywords.

🧠 Search Intent

The reason behind a search (researching, comparing, or buying).

Understanding intent is more important than just chasing high search volume.

🛠 Step-by-Step Keyword Research Framework

Step 1: Start With Customer Thinking (Not Tools)

Ask:

  • What problem does my product solve?

  • What would a customer type if they didn’t know my brand?

  • What features matter most (size, material, use case)?

Example:
Instead of “premium hydration solution,” a customer types “gym water bottle.”

✅ Focus on how customers speak — not how brands market.

Step 2: Identify Seed Keywords

Seed keywords are broad, primary phrases describing your product.

Examples for a garlic press:

  • garlic press

  • stainless steel garlic crusher

  • garlic mincer

How to find them:

  • Amazon search bar autocomplete

  • Competitor listing titles

  • Customer reviews (look for repeated phrases)

🔹 Pro Tip: If it appears in Amazon autocomplete, customers are searching it.

Step 3: Expand Into Long-Tail Keywords

Long-tail keywords are more specific and often convert better.

Example:

  • “garlic press” → high competition

  • “easy clean stainless steel garlic press” → higher intent

Benefits:

  • Lower PPC cost

  • Higher conversion rates

  • Easier ranking

🔹 Pro Tip: Long-tail keywords often contain 3–5 words and reflect buying intent.

Step 4: Analyze Search Intent

Not all traffic is good traffic.

Compare:

  • “best garlic press” → research intent

  • “garlic press stainless steel dishwasher safe” → buying intent

Prioritize keywords showing:

  • Specific features

  • Size or quantity

  • Problem-solving language

Step 5: Categorize Keywords by Strategy

Organize keywords into:

🎯 Primary Keywords

High-volume, highly relevant, used in:

  • Title

  • Main image alt-text (if applicable)

  • PPC campaigns

📦 Secondary Keywords

Used in:

  • Bullet points

  • Description

  • A+ Content

🗂 Backend Keywords

Misspellings, alternate phrasing, Spanish terms (if relevant).

Avoid repetition — Amazon indexes once.

Step 6: Apply Keywords Strategically

Where to place them:

  • Title → Most important keyword first

  • Bullet Points → Features + secondary keywords

  • Product Description / A+ Content → Supporting keywords

  • Backend Search Terms → Variations and hidden keywords

⚠️ Avoid keyword stuffing. Readability affects conversion rate.

Step 7: Validate With PPC Data

Launch an Automatic Campaign in Amazon Ads.

Review:

  • Search Term Report

  • CTR (Click-Through Rate)

  • Conversion Rate

  • ACOS

Move converting search terms into Manual Exact campaigns.

🔹 Pro Tip: PPC data reveals real buyer behavior, not just search volume.

⚠️ Common Keyword Research Mistakes

❌ 1. Chasing High Search Volume Only

Do this instead:

  • Balance volume with relevance and intent.

❌ 2. Keyword Stuffing Titles

Why:

  • Fear of missing ranking opportunities

Problem:

  • Lower readability → lower conversion rate

Instead:

  • Write for humans first, algorithm second.

❌ 3. Ignoring Backend Search Terms

Why:

  • Sellers don’t know where they are

Problem:

  • Missed indexing opportunities

Instead:

  • Use backend for synonyms and alternate phrasing.

❌ 4. Not Using PPC Data

Why:

  • PPC seen only as advertising

Problem:

  • Missed keyword validation data

Instead:

  • Treat PPC as a keyword research tool.
