Best overall for serious sellers: Helium 10 (Cerebro + Magnet) — unmatched reverse-ASIN depth + workflow for PPC & listing builds. Helium 10 Project FBA
Best for beginners / quick wins: Jungle Scout (Keyword Scout) — simpler UI, multi-ASIN reverse search up to 10 at once. Jungle ScoutSaaSGenius.com
Best “first-party” data (brand-registered only): Amazon Brand Analytics – Search Query Performance (SQP) + Product Opportunity Explorer — actual shopper queries + funnel metrics straight from Amazon. Amazon Seller Central Sell on Amazon
Nice supplemental dataset: MerchantWords — broad shopper-search trends; use to expand long tails, not to replace H10/JS. merchantwords.com +1

How we judged

Data quality & recency (reverse-ASIN depth, misspellings, long-tail coverage)
Speed to insights (filters, bulk actions, “find gaps fast”)
PPC readiness (match types, sponsored rank, historical trend)
Price-to-value for different seller stages

1) Helium 10 — Magnet + Cerebro (Best Overall)

Why it wins: Cerebro’s reverse-ASIN is still the gold standard for harvesting what top competitors actually rank for; Magnet helps you expand, dedupe, and prioritize terms before you ship to listing/PPC. Helium 10 Project FBA

Standout bits

Reverse search a competitor ASIN → get organic + sponsored terms, ranks, and opportunity metrics. Helium 10
Tight workflow into listing tools (Frankenstein/Scribbles) and PPC (Adtomic). eplaybooks.com

Pricing (2025 snapshot): Starter $29/mo, Platinum $84/mo, Diamond $209/mo, Elite $399/mo. If keyword work is daily, Platinum+ is the sweet spot. RevenueGeeks.com

Use if you: run multiple SKUs, need deep competitor mining, and want PPC + listing ops in one place.

2) Jungle Scout — Keyword Scout (Best for Beginners)

Why it’s great: Cleaner UI, lower learning curve, and reverse-search up to 10 ASINs at once to compare overlaps/gaps. Perfect when you want signal quickly without heavy tuning. Jungle Scout

What you get

Real Amazon search data (volume, PPC costs, trends) + reverse-ASIN organic/sponsored views. SaaSGenius.com
Pricing commonly starts around $49/mo on current plans. DemandSage Jungle Scout

Use if you: want speed + simplicity for product validation and starter keyword sets.

3) Amazon Brand Analytics (SQP) + Product Opportunity Explorer (Best First-Party Data)

Why you should care: it’s Amazon’s own. SQP shows your funnel by search query (impressions → clicks → purchases) for your brand terms; Product Opportunity Explorer reveals niche demand and seasonality. Amazon Seller Central Sell on Amazon

Caveat: SQP requires Brand Registry and is strongest for your branded/close-category queries, not broad market recon. Influencer Marketing Hub

Use if you: are brand-registered and want to prioritize which queries truly move the needle.

4) MerchantWords (Great for Long-Tail Expansion)

What it’s good for: super quick shopper-search trend discovery and exploratory long-tail ideas; shows monthly search estimates and trend graphs. Don’t rely on it alone for PPC bids. merchantwords.com +1

Use if you: need brainstorm fuel to widen your net before validating in Helium 10/Jungle Scout.
