Cerebro is the most praised tool in the Helium 10 suite — G2 reviewers consistently call it "best-in-class" for keyword research. It reverse-engineers any competitor's listing to reveal every keyword they rank for, how much traffic those keywords drive, and where the gaps are in their strategy. Here's how to actually use it.
If you've been searching for a Helium 10 Cerebro tutorial, want to understand how to do reverse ASIN lookup on Amazon, or need to learn how to use Cerebro for keyword research step by step, this guide walks through every feature with real examples. We also explain the Cerebro IQ Score, show you the best Cerebro filter settings for finding profitable keywords, and cover how to use Cerebro for PPC keyword mining in 2026.
Cerebro is a reverse ASIN lookup tool. Paste in any Amazon product's ASIN (the unique product identifier), and Cerebro returns every keyword that product ranks for — often thousands of them. For each keyword, you see:
Helium 10 claims a database of over 450 million keywords with daily updates. The data comes from Amazon's own search ecosystem, processed through machine learning models — not third-party clickstream data.
Go to Amazon, find a top-selling competitor in your niche, and copy the ASIN from the product URL or the "Product Information" section. The ASIN is the 10-character code starting with B0.
Open Cerebro in your Helium 10 dashboard. Paste the ASIN and hit "Get Keywords." Cerebro typically returns results in 10-30 seconds. You can also paste multiple ASINs (up to 10) to compare keyword strategies across competitors.
Raw Cerebro results can return 5,000+ keywords — most of which are irrelevant. Use these filters to find the winners:
After filtering, you typically have 50-200 high-value keywords — the real gold.
Export filtered keywords as CSV. These go into three places:
The IQ Score compares monthly search volume against the number of competing products. A keyword with 3,000 searches and only 100 competing products will have a much higher IQ Score than one with 3,000 searches and 20,000 competitors.
In practice, an IQ Score above 3 is good. Above 5 is excellent — these are underserved keywords with real demand. Below 1 usually means the keyword is too competitive or too low-volume to bother with.
The IQ Score doesn't account for listing quality, review count, or brand strength of competitors. A keyword with a high IQ Score but where the top 10 results all have 2,000+ reviews is still going to be hard to crack. Always cross-reference with manual analysis of page 1 results.
Cerebro's most powerful feature is comparing up to 10 ASINs simultaneously. Paste in your top 5-10 competitors and filter for keywords where 3+ competitors rank but you don't. These are proven, high-converting keywords that you're missing — the single fastest way to find ranking opportunities.
You can also filter for keywords where only 1-2 of the 10 competitors rank. These are "hidden" keywords that most sellers in your niche haven't discovered yet.
One of the most underused Cerebro strategies is mining competitor PPC keywords. Filter for keywords where a competitor has a sponsored rank but low or no organic rank — this tells you which keywords they're paying for. If they keep paying for a keyword, it's converting. Add these to your own campaigns.
According to G2 reviews, sellers consistently report finding 30% more relevant keywords with Cerebro compared to manual research. Multiple reviewers describe Cerebro as "the best keyword research tool for Amazon" specifically because all data comes directly from Amazon's search ecosystem rather than Google or clickstream proxies.
Helium 10 made significant pricing changes in early 2026. The Starter plan was retired for new users, making Platinum the entry-level paid tier:
| Plan | Monthly | Annual (per month) | Cerebro usage |
|---|---|---|---|
| Free | $0 | $0 | Demo (2/day) |
| Platinum | $129 | $99 | 250/month |
| Diamond | $359 | $279 | Unlimited |
For most sellers, Platinum's 250 monthly searches is sufficient — that's 8+ Cerebro analyses per day. If you're managing a large catalog or running an agency, Diamond's unlimited access becomes necessary.
Note: Helium 10 also charges a 2% management fee on PPC spend for accounts managed through their Helium 10 Ads tool on both Platinum and Diamond plans.
