Cerebro is one of the most valuable tools in Helium 10โ€™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 โ€” and how well theyโ€™re performing.

โœ… How Cerebro Works:

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

The tool then analyzes that product and gives you a complete list of keywords itโ€™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 โ€“ a proprietary score showing the balance between demand (search volume) and competition

๐Ÿง  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

๐Ÿš€ Pro Tip:

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