Amazon Keyword Research & Rank Tracker: Reverse ASIN

Find every keyword an Amazon product ranks for, get Amazon monthly search volume and related keywords, and track the organic and sponsored rank of your ASINs for your keywords every day, with the change since the last check. Built for Amazon FBA sellers, brand owners and Amazon agencies who want reverse-ASIN and rank-tracking data without a $39–$279/month seller-tool subscription.

Pay only for results: $0.002 per keyword and $0.006 per rank check (per 100 results checked), plus $0.03 per run with results and $0.02 per keyword-database request. No Seller Central login, no browser extension, no API key.

What it does

Mode	Input	You get	Marketplaces
Reverse ASIN (default)	1–10 ASINs or product links	The keywords each product ranks for on Amazon search, with monthly searches and its organic rank	US, UAE, Saudi Arabia, Egypt
Related keywords	1–20 seed keywords	Keywords Amazon shoppers search around your seed, with monthly searches	US, UAE, Saudi Arabia, Egypt
Search volume	Up to 1,000 keywords	Amazon monthly searches for your own keyword list	16 Amazon stores
Rank tracking	ASINs × up to 100 keywords	Live organic rank, position including ads, sponsored rank, top 3 competitors, and rank change vs the last run	15 Amazon stores

Rank tracking keeps history for you. Each run stores the latest rank (and up to 60 daily data points) in a key-value store in your Apify account. The next run adds previousRank, rankChange (+ means you moved up) and change: first_check, up, down, same, entered (now in results), lost (dropped out) or not_ranked. Schedule it daily and you have a rank tracker.

Filters run before you are charged: min/max monthly searches, max organic rank (reverse ASIN, for example only page-one keywords), must contain / must not contain words. Duplicates are removed and never charged.

Only public product information is returned (title, price, rating, review count, badges). No seller names, reviewer data or personal data.

Use cases

• Spy on a competitor's listing: reverse-ASIN their best seller and copy the high-volume keywords you are missing into your title, bullets and backend search terms.
• Plan a PPC campaign: related keywords with min monthly searches 500 give a ready keyword list for Sponsored Products.
• Check a product idea: search volume for 50 niche keywords tells you whether shoppers actually look for it.
• Track your launch: daily rank tracking of your ASIN for 20–100 target keywords shows whether your listing changes, coupons and ads move you up.
• Agency reporting: one scheduled run per client, results straight into Google Sheets or Looker Studio.

Event	Price
Run with results	$0.03 (once per run, only when at least one result is returned)
Keyword	$0.002 per keyword (reverse ASIN, related keywords, search volume)
Rank check	$0.006 per ASIN × keyword × page of 100 live Amazon results checked
Keyword database request	$0.02 per request that returned keywords (reverse ASIN, related, volume; see below)

Paid Apify plans pay less per keyword and per rank check, applied automatically.

Worked examples

• Reverse ASIN, 100 keywords for one product: $0.03 + $0.02 + 100 × $0.002 = $0.25
• Related keywords, 5 seeds × 100: $0.03 + 5 × $0.02 + 500 × $0.002 = $1.13
• Search volume for 1,000 keywords: $0.03 + $0.02 + $2.00 = $2.05
• Daily rank tracking, 1 ASIN × 20 keywords, top 100: $0.03 + 20 × $0.006 = $0.15 per day (about $4.50 per month)
• Same, but looking through the top 300 (depth 3): $0.03 + 20 × 3 × $0.006 = $0.39 per day
• 3 ASINs × 50 keywords every day, top 100: $0.93 per day

What counts as a keyword database request: each lookup in the Amazon keyword database. Reverse ASIN makes one request per ASIN, related keywords one per seed keyword (all related levels come back in that one request), search volume one per batch of up to 1,000 keywords. Rank tracking has no request fee; it is billed only by rank checks. ASINs or seeds that return nothing, or whose keywords are all removed by your filters, are not charged.

Rank check depth: each page of 100 Amazon results you ask to check is one rank check per ASIN. Top 100 = 1, top 200 = 2, top 300 = 3.

You are never charged for runs without results, ASINs or seeds that return nothing, keywords where Amazon returned no results, provider errors, keywords removed by your filters or duplicates. Set Maximum cost per run in the run options and the Actor stays inside that budget.

Apify Free plan: 1 ASIN, 1 related seed keyword, 50 keywords per ASIN or seed, 50 volume keywords and 5 tracked keywords per run, so you can try it on your own product. Paid Apify plans get the full limits.

FAQ

Where does the data come from? Keyword and search-volume data come from DataForSEO's Amazon keyword database (refreshed monthly; every row shows volumeUpdatedAt). Rank tracking reads live Amazon search results at the time of the run.

How long does rank tracking take? Usually 1–5 minutes; at busy times up to about 40 minutes. It is built for scheduled daily runs, not instant checks. Keywords whose results did not arrive in time are not charged.

What do organicRank, rankAbsolute and sponsoredRank mean? organicRank is the position among organic results only (1 = first organic product). rankAbsolute counts every result on the page, including ads. sponsoredRank is the position among sponsored products if your ASIN also appears as an ad.

Why is my ASIN "not_ranked"? It was not in the top 100 (or 200/300 with a deeper setting) for that keyword. Increase Rank tracking depth to look further (each extra 100 results is one more rank check).

Why does reverse ASIN only work in 4 marketplaces? The keyword database covers Amazon US, UAE, Saudi Arabia and Egypt for reverse ASIN and related keywords. Search volume and rank tracking cover the other stores.

Do numbers match my seller tool? Search volumes are estimates, and every tool models them differently. Expect the same order of magnitude and the same ranking of keywords, not identical numbers.

Can I track the same keywords for several products? Yes. Up to 10 ASINs per run; each Amazon results page is checked once and matched against all your ASINs.

Is this affiliated with Amazon? No. It is an independent tool by SteadyScrape (steady-scrape) and returns only public information.
