What Cerebro does

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:

• Search volume, estimated monthly searches on Amazon
• Organic rank, where the product appears in organic results for that keyword
• Sponsored rank, where it appears in paid results
• Cerebro IQ Score, a proprietary demand-to-competition ratio (higher = better opportunity)
• CPR 8-Day Giveaway, estimated units to give away in 8 days to reach page 1 for that keyword
• Competing products, how many ASINs rank for the same keyword

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.

Step-by-step: running your first Cerebro search

Step 1: Find a competitor ASIN

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.

Step 2: Paste into Cerebro

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.

Step 3: Apply smart filters

Raw Cerebro results can return 5,000+ keywords, most of which are irrelevant. Use these filters to find the winners:

• Search volume: minimum 500/month (filters out keywords nobody searches for)
• Organic rank: 1-20 (only keywords where the competitor actually ranks well)
• Word count: 3+ words (long-tail keywords are easier to rank for and convert better)
• Cerebro IQ Score: 2+ (filters out oversaturated keywords)

After filtering, you typically have 50-200 high-value keywords, the real gold.

Step 4: Export and apply

Export filtered keywords as CSV. These go into three places:

1. Listing optimization: Add top keywords to your title, bullet points, and backend search terms using Helium 10's Scribbles tool
2. PPC campaigns: Create exact-match manual campaigns targeting the highest-volume keywords
3. Keyword Tracker: Monitor your ranking progress on the 20-50 most important keywords

The Cerebro IQ Score, explained

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.

Advanced technique: multi-ASIN analysis

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.

Cerebro for PPC keyword mining

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.

What Cerebro costs in 2026

Helium 10 made significant pricing changes in early 2026. The Starter plan was retired for new users, making Platinum the entry-level paid tier:

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.
