Keyword Research Tool: keyword ideas and Amazon reverse ASIN lookup

A keyword research tool for SEO and marketplace sellers. Turn one seed keyword into hundreds of keyword ideas with search volume, CPC and difficulty from Google suggestions, related searches, A-Z autocomplete and Amazon related searches, or enter any Amazon ASIN and get the search keywords that product ranks for (reverse ASIN). Every idea can be screened against live USPTO trademarks, so Merch by Amazon, KDP, Etsy and Redbubble sellers can drop risky words before they design.

Built for Amazon Merch on Demand, KDP, Etsy, Redbubble and print-on-demand sellers. It also works for any SEO or content team that needs long-tail keyword research.

Five ways to find keywords

Mode (mode)	You enter	You get
google_suggestions (default)	seed keyword	Long-tail Google keywords that contain the seed, with volume, CPC, difficulty and intent
google_related	seed keyword	Google "related searches", 1 to 4 levels deep
amazon_related	seed keyword	Related searches from Amazon with Amazon search volume (US, EG, SA, AE)
reverse_asin	ASIN, ISBN-10 or Amazon URL	Amazon keywords the product ranks for, its rank for each, and its title, price, rating and reviews
autocomplete	seed keyword	What Google suggests as you type: the seed, seed + a..z and/or question words, with volume

Why this Actor

• Reverse ASIN for Merch and KDP. Enter a best-seller's ASIN and see which searches bring it traffic. For example, "Cat What?" shirt B07YHZR726 ranks #11 for "funny cat t shirts" (19,111 Amazon searches a month). "100 Flowers" coloring book 1661264107 ranks #2 for "flower coloring books" (18,887).
• No zero-volume clutter. Most long-tail keywords have 0 or unknown volume. The default minSearchVolume: 1 removes them before delivery, so you neither see them nor pay for them. Set it to 0 to keep everything.
• Trademark flag on every idea. It uses the same engine as our POD & KDP Trademark Checker and about 4.4 million live US marks. "doja cat t shirts" and "sam and cat merchandise" come back high risk. Set excludeTrademarkRisk to drop risky ideas automatically.
• You only pay for ideas you get. Seeds with no ideas, failed lookups, duplicates, filtered-out keywords and invalid input are never charged.
• Hard spending cap. Set maxTotalChargeUsd or Apify's "Max cost per run". The run fetches only what fits under the cap, then stops cleanly and lists the seeds it did not reach.
• No duplicates across seeds. An idea already delivered for an earlier seed is not repeated or charged again.

Output

The dataset has one type: "idea" row per keyword and one type: "seed" summary row per seed. Example idea row (shortened):

{
  "type": "idea", "keyword": "funny cat t shirts", "seed": "B07YHZR726", "mode": "reverse_asin", "rankInSeed": 1,
  "searchVolume": 19111, "searchVolumeSource": "amazon", "volumeStatus": "ok", "wordCount": 4,
  "asin": "B07YHZR726", "amazonRank": 11,
  "trademarkRisk": "medium", "trademarkFlaggedPhrases": ["cat"],
  "location": "United States", "checkedAt": "2026-10-16T02:10:00Z"
}

Google modes also return monthlySearches, trend, cpcUsd, competition, competitionLevel, top-of-page bids, keywordDifficulty (0 to 100) and searchIntent. Autocomplete rows add autocompleteQuery and autocompleteRank.

volumeStatus is ok (volume ≥ 1), zero (the provider reports 0) or unknown (no data).

Each seed row shows status (ok, no_results, error or not_processed), ideasAvailable, ideasDelivered, and filteredOut counts (below min volume, excluded words, duplicate of an earlier seed, trademark, beyond max results). In reverse-ASIN mode it also shows the product's title, price, rating and review count.

Pricing (pay per event)

Event	Price	When
seed-processed	$0.02	A seed or ASIN that returned at least one idea (Labs modes)
keyword-idea	$0.002	Each idea delivered
autocomplete-query	$0.004	Each autocomplete lookup that returned suggestions

Examples:

• 1 seed × 100 ideas = $0.22.
• 1 ASIN × 40 ideas = $0.10.
• 1 autocomplete seed with A–Z and 100 ideas ≈ $0.31.

Use from AI agents (MCP)

AI assistants such as Claude, ChatGPT and Cursor can run this Actor through Apify's MCP server (https://mcp.apify.com). The agent can look up the Actor, read its input schema, run it and read the results. Runs use your own Apify account and are charged at the prices on this page.

• Actor name: vncntlabs/keyword-ideas
• Server URL with only this tool: https://mcp.apify.com?tools=vncntlabs/keyword-ideas. The default https://mcp.apify.com also works; the agent can then search Apify Store and call the Actor by name.
• Claude (desktop app or claude.ai): Settings > Connectors > Add custom connector, paste the server URL, then sign in to Apify.
• ChatGPT: turn on Developer mode, then Settings > Apps & Connectors > Create, paste the server URL and choose OAuth.
• Cursor: run /add-plugin apify in Cursor chat and connect the Apify MCP server under Cursor Settings > Tools & MCPs, or add the server to mcp.json:

{ "mcpServers": { "apify": { "url": "https://mcp.apify.com?tools=vncntlabs/keyword-ideas" } } }

Example prompt: "Use the Apify Actor vncntlabs/keyword-ideas to find 100 keyword ideas for "camping mug" with search volume and CPC, sorted by search volume."

To cap the cost of an agent's run, it can pass maxTotalChargeUsd in the run options.

Tips

• Merch shirts: run reverse_asin on 3 to 5 best-sellers in your niche with excludeTrademarkRisk: "high". Then put the best ideas into our Keyword Search Volume Actor to compare Google and Amazon.
• KDP: amazon_related with includeWords: ["book", "journal", "coloring"] keeps Amazon's broad related products (markers, pencils) out of the results.
• Long-tail hunting: reverse_asin with minSearchVolume: 0 and sortBy: "relevance" shows every keyword the product ranks for, best rank first. Many of them have zero measured volume but still convert.

Notes and limits

• Search volumes are third-party estimates from DataForSEO. Google volume comes from a Google Ads-based database; Amazon volume comes from DataForSEO's Amazon keyword data. Google volume does not measure Etsy or Redbubble search.
• An ASIN that is new or not ranked in the selected market returns no_results and is not charged.
• The trademark screen is automated and is not legal advice. Common words that are also registered marks (for example "cat", "canada") are flagged medium. Check the TSDR link before you decide.
