1. Helium 10 – Powerful but Premium

When it comes to Amazon keyword research, Helium 10 is one of the most well-known and feature-rich tools on the market.

Below two amazon keyword research tool make it a favorite among advanced sellers:

🔍 Helium 10 Cerebro – Reverse ASIN Lookup Tool

Cerebro is one of the most valuable tools in Helium 10’s suite, especially for competitive analysis and keyword research.

What makes Cerebro unique is that it allows you to see exactly what keywords your competitors are ranking for — and how well they’re performing.

✅ How Cerebro Works:

Instead of guessing which keywords might work, you simply take an ASIN (Amazon Standard Identification Number) from a competitor’s product and enter it into Cerebro.

The tool then analyzes that product and gives you a complete list of keywords it’s indexed and ranked for.

This includes:

• Organic rankings (what keywords the product shows up for in organic search)
• Sponsored keywords (used in paid ads)
• Search volume (how many people are searching for the keyword each month)
• Cerebro IQ Score – a proprietary score showing the balance between demand (search volume) and competition

🧠 Why Use Cerebro:

• Spy on competitors to uncover high-converting keywords
• Find hidden opportunities in keywords others may be missing
• Build keyword-rich listings using real data instead of assumptions
• Validate niches by looking at top-performing ASINs

🚀 Pro Tip:

You can analyze up to 10 ASINs at once, which helps you find overlapping keywords across multiple competitors — a great way to identify buyer intent keywords with proven performance.

🔍Helium 10 Magnet – Best Keyword Research Tool for Amazon?

The Helium 10 Magnet tool is a keyword research tool designed specifically for Amazon sellers. It helps you generate a large list of relevant keywords based on a seed keyword you enter.

Here’s what Magnet does:

• 🔍 Finds high-volume keywords related to your input keyword
• 📈 Provides key metrics like search volume, CPC, number of competing products, and keyword relevancy
• 🧠 Suggests long-tail keywords, variations, and related terms you might not have considered
• ✅ Helps you choose the most profitable and relevant keywords for your Amazon listings or PPC campaigns

How it’s different from Cerebro:

• Magnet starts with a keyword → shows related keyword ideas
• Cerebro starts with an ASIN → shows keywords your competitor ranks for

Magnet is great for building a keyword list from scratch, especially when you’re still exploring niche ideas or optimizing a product listing.

However, Helium 10’s robust toolkit comes at a price. Their pricing plans can be expensive for beginners who are just testing the waters.

For those on a tight budget, Helium 10 does offer a free plan with limited access — which can be a good way to explore some of its core features before committing.
