Mode	Input	You get
Search volume	Keywords	Estimated monthly searches per keyword
Reverse ASIN	Up to 25 ASINs per run	Up to 100 keywords per product, with volume, position, organic or sponsored, and product details
Competitors	ASINs	Up to 100 products sharing the most keywords with each one, with overlap numbers
ASIN overview	ASINs	Keywords in the top 1, 3 and 10, organic and sponsored, and volume totals
Shared keywords	2-10 ASINs	Up to 90 keywords all of them rank for, with each product's position

Why Use This Actor?

• Search volume numbers, not autocomplete guesses. Each keyword comes back with an estimated monthly search count.
• Small lists stay cheap. Three keywords cost $0.03 in total, with no large per-run minimum.
• You don't pay for thin products. Before a reverse ASIN lookup, the actor checks how many keywords the product ranks for and skips it without a lookup charge if that is under your minimum.
• Competitor and overlap data in the same actor. Find rival products by shared keywords, then compare them.
• Sorted by what matters. Reverse ASIN and shared keyword rows come highest volume first.
• Every ASIN is accounted for. An ASIN without data gets a free row saying why.

Use Cases

• Keyword prioritization: rank a list of ideas by monthly searches before writing a listing.
• Listing optimization: see the terms a rival product places for and work them into titles, bullets and backend terms.
• PPC planning: build Sponsored Products lists from real demand, and see where a rival shows as sponsored.
• Competitor discovery: find the products that fight for the same searches as yours, including ones you did not know about.
• Product research: size demand around an idea, and compare how well the current sellers cover it.
• Agency reporting: a keyword overview per client ASIN, on a schedule.

How It Works

1. Pick a mode and paste keywords or ASINs. Product links work too.
2. Keywords and ASIN overviews go in blocks of 20. Other modes look up one ASIN, or one comparison, at a time.
3. Before each paid lookup, the actor checks that your spending limit can pay for it. If it cannot, the run stops cleanly with what it has.
4. You are charged only when a lookup returns rows.

Input Configuration

Field	Type	Description
mode	string	searchVolume (default), reverseAsin, competitors, asinOverview or sharedKeywords.
keywords	array	For search volume. Up to 5,000 per run, each at most 80 characters and 10 words.
asins	array	For the other modes. ASINs or amazon.com product links. Reverse ASIN takes 25 per run, shared keywords 2-10, the others 200.
minKeywords	integer	Reverse ASIN only. Skip products ranking for fewer keywords than this. 1-100, default 10.

An empty input runs the search volume example above, and the log says so.

Key Output Fields

Field	Meaning
monthlySearchVolume	Estimated monthly searches on amazon.com for the whole keyword, not traffic to one product. 0 means very low. null means not enough searches to report.
position	Place on the results page, counting organic and sponsored together.
resultType	organic or sponsored.
competingResults	Total results for the keyword, a rough measure of competition.
rankedAt	When the position was seen. It can be several weeks old and differs per keyword.
keywordsReturned, keywordsTotal	How many keywords this row set holds, out of how many the product ranks for.
status	ok, no-data, too-few-keywords or lookup-failed. Rows other than ok are free.

Pricing

Event	When	Price
Actor start	Once per run	$0.005
Keyword volume block	Each block of up to 20 keywords	$0.025
ASIN overview block	Each block of up to 20 ASINs. Reverse ASIN uses it as its check.	$0.025
Competitor lookup	Each ASIN, up to 100 competitors	$0.05
Shared keywords lookup	Each comparison, up to 90 keywords	$0.05
Reverse ASIN lookup	Each ASIN, up to 100 keywords	$0.49

Examples: 3 keywords = $0.03. 1,000 keywords = 50 blocks = $1.255. Reverse ASIN on 1 product = $0.005 + $0.025 + $0.49 = $0.52.

A block is charged in full even when it is not full, and a lookup costs the same however many rows it returns. An unknown keyword still counts as part of its block.

FAQ

Which Amazon stores are covered? amazon.com (US) only. A link to another store is looked up by its ASIN on amazon.com, and the log warns you.

Are the volumes exact? No. Amazon does not publish search counts, so every tool estimates. Use them to compare keywords. Different tools can differ a lot on the absolute numbers.

Does reverse ASIN return every keyword? No, up to 100 per product, and they are the keywords where the product places best, not the highest-volume ones. Products ranking for under 100 keywords get all of them. For a large product with thousands of keywords, keywordsTotal shows the full count, and many of the 100 rows are low-volume terms. Use ASIN overview to see the totals first.

Why was my product skipped? It ranks for fewer keywords than minKeywords (default 10). Set it to 1 to look it up anyway.

What am I charged when there is no data? Nothing for that lookup. You get a free no-data row. Only the start fee, and in reverse ASIN mode the overview block when at least one ASIN in it has data, apply.

Why did a run stop early? Your spending limit could not pay for the next lookup. No lookup is sent that the limit cannot cover.
