Amazon Keyword Research & Reverse ASIN Tool

Find every Amazon keyword a product ranks for, with its ranking position and monthly Amazon search volume, and expand seed terms into related keywords worth targeting. Reverse-ASIN lookup plus keyword research for Amazon SEO, PPC and product launches on amazon.com, with no subscription.

What does the Amazon Keyword Research & Reverse ASIN Tool do?

It has two modes:

• Reverse ASIN: give it one or more ASINs and get back the Amazon search terms each product ranks for, with ranking position and monthly search volume, sorted by volume. Use it to see a competitor's keyword coverage or audit your own listing.
• Keyword research: give it seed terms and get related Amazon keywords, each with its monthly Amazon search volume, sorted from highest to lowest. Use it to build listing copy and PPC keyword lists.

Data covers the US marketplace (amazon.com).

Use cases

• Competitor research: reverse-engineer which search terms drive a rival product's organic rankings.
• Listing optimization: find high-volume keywords to work into titles, bullets and backend search terms.
• PPC campaigns: build exact- and phrase-match lists with real Amazon search volume behind every term.
• Product launch research: size demand around a product idea before sourcing it.
• Rank audits: check which keywords your own ASIN already ranks for, and where.

How to use it

1. Choose a Mode: Reverse ASIN or Keyword research.
2. For Reverse ASIN, paste ASINs into ASINs (up to 50 per run). For Keyword research, paste seed terms into Seed keywords (up to 50 per run).
3. Set Max keywords per ASIN or Max related keywords per seed (default 50, max 200).
4. Optionally set Max budget (USD) to stop a run whose worst-case charge would exceed it, and a Webhook URL to receive the run summary.
5. Click Start, then export the results as JSON, CSV or Excel, or read them through the Apify API.

• rank is the product's position in Amazon search results for that keyword.
• data_status is ok when data was found and no_data when the ASIN or seed has no keyword data. no_data records are delivered so you can see every input, but they are never billed.
• The last row of every run is a run_summary record (records returned and billed, charge), which is also saved to the key-value store as OUTPUT.

How much does it cost?

Pay per event, with no subscription or API key.

Event	Free / Bronze plan	Silver plan	Gold plan and above
ASIN analyzed (Reverse ASIN, per ASIN with data)	$0.07	$0.063	$0.056
Seed keyword expanded (Keyword research, per seed with data)	$0.15	$0.135	$0.12
Actor start (once per run)	$0.001	$0.0009	$0.0008

At the default limits (50 keywords per ASIN, 50 related rows per seed) you pay exactly the event prices. The data provider also bills per row, so on very deep lookups (above roughly 85 keywords per ASIN, or close to 200 related rows per seed) a minimum-request charge adds extra units to cover that cost.

Worked examples at Free/Bronze prices:

Run	Charge
1 ASIN, 50 keywords	$0.001 + $0.07 = $0.071
3 ASINs, 10 keywords each	$0.001 + 3 × $0.07 = $0.211
2 seed keywords, 50 related each	$0.001 + 2 × $0.15 = $0.301
1 ASIN with 200 ranking keywords returned	$0.001 + 2 × $0.07 = $0.141 (one minimum-request unit)

FAQ

Which Amazon marketplaces are supported? The US marketplace, amazon.com. The data source has no keyword rankings or search volumes for other Amazon marketplaces.

Where does the search volume come from? It is Amazon search volume (monthly searches on Amazon), not Google search volume.

What if an ASIN has no data? You get a record with data_status: "no_data" and an empty keyword list, and you are not charged for it. New or very low-traffic listings often have no ranking data yet.

Can I analyze many ASINs at once? Yes, up to 50 ASINs or 50 seed keywords per run, processed in parallel.

How do I keep costs predictable? Set maxBudgetUsd. The actor works out the worst-case charge before making any request and stops if it is over your cap.
