Amazon Keyword Research: Search Volume & Reverse ASIN

An Amazon keyword research tool with three modes in one Actor:

1. Amazon search volume: paste up to 10,000 keywords and get the monthly Amazon searches of each one.
2. Related keywords: give seed keywords, get the related searches Amazon shoppers type, with their volume.
3. Reverse ASIN: give a product ID (ASIN), get the Amazon searches it ranks for, with its rank, the search volume and the product's price and rating shown in the results.

16 Amazon markets for search volume. You pay $0.0006 per keyword with data, plus a $0.03 fee per batch of 250 keywords, per seed keyword or per ASIN. Keywords without volume come back free, so you know they were checked. It also works as an MCP tool for AI agents.

Typical uses

• Check the Amazon search volume of your listing keywords before writing a title, bullets or backend search terms.
• Find long-tail Amazon keywords around a product idea (related keywords, up to 1,000 per seed).
• Reverse ASIN a competitor: see which searches bring its traffic and where it ranks, then target the same keywords.
• Size a niche: total monthly Amazon searches for a list of product keywords, per country.
• Feed keyword data into Google Sheets, n8n / Make workflows or an AI agent.

Why this one

• Three tools in one: Amazon search volume, related keywords and reverse ASIN lookup, same output format.
• Low cost per keyword: 1,000 keywords that all have volume cost $0.72; a reverse ASIN with 100 keywords about $0.09.
• No charge for keywords without data, for a seed or ASIN with nothing found beyond its fee, nor for a request the source failed to answer.
• Hard cost cap: the run stops before the maximum cost you set.
• No Amazon account, no browser, no Amazon page opened: the data comes from a commercial e-commerce keyword data provider.

Pricing

• $0.0006 per keyword with data: a keyword with an Amazon search volume, a related keyword, or a keyword the ASIN ranks for.
• plus $0.03 per Amazon lookup: one per seed keyword, one per ASIN, or one per batch of up to 250 keywords in search volume mode (1 to 250 keywords = 1 batch, 251 to 500 = 2). Charged only once the data source has answered.

Examples: 100 keywords with volume cost about $0.09; 1,000 keywords with 800 found about $0.60; a reverse ASIN or a seed keyword with 100 keywords about $0.09. No subscription. See the Pricing tab for the current prices. Keywords without volume, duplicates and invalid values are never billed. Input mistakes (unsupported market, empty list) stop the run with a clear message and cost nothing. The run never spends more than the maximum cost you set.

Free Apify plan: each run checks the first 20 keywords, or 2 seed keywords / ASINs with 20 keywords each, so you can test the output. A paid Apify plan removes this limit.

Run summary

Each run also stores a summary in the key-value store (OUTPUT): keywords checked, with and without data, lookups charged, per seed or ASIN the number of keywords available and returned, duplicates removed, invalid values with the reason, and anything skipped because of the free-plan or budget limit.

Limits

• Search volumes are estimates from a commercial data provider, not numbers published by Amazon. Very new or very rare keywords may have no data.
• Ranks are those the provider saw at rankCheckedAt, not live positions.
• Related keywords and reverse ASIN: US, UAE, Saudi Arabia and Egypt only.
• The same keyword may appear under two seeds: each seed gets its own list.
• This tool is not affiliated with Amazon. Amazon is a trademark of Amazon.com, Inc.
• For Google volumes, use PlainRows Keyword Search Volume; for Amazon products, PlainRows Amazon Product Search Scraper.

FAQ

How do I check the Amazon search volume of many keywords at once? Keep the mode on Amazon search volume, paste your keywords (up to 10,000), pick the market and run. You get one row per keyword with its monthly Amazon searches.

What is a reverse ASIN lookup? You give a product's ASIN; the tool returns the Amazon searches the product appears for, its rank on each, and the search volume, sorted by volume or by rank.

Which countries are covered? Search volume: 16 Amazon markets (list above). Related keywords and reverse ASIN: United States, UAE, Saudi Arabia and Egypt.

What does it cost for 1,000 keywords? 4 batch fees ($0.12) plus $0.0006 per keyword with volume: about $0.60 if 800 of them have data. Keywords without data are free.

Can I use it in Google Sheets, n8n, Make or an AI agent? Yes: through the Apify API, the Apify integrations for n8n, Make and Zapier, or the Apify MCP server (see above).
