MerchantWords Review (2026): Is It Worth It for Amazon Keyword Research?
MerchantWords is an Amazon keyword database. It collects search terms from Amazon’s search bar, estimates how often each is searched, and adds reverse ASIN lookups, daily rank tracking and trend tools. Plans cost $35, $79 or $149 a month, or $350 to $1,490 a year; Enterprise is $749 a month through sales, and there is no free trial (checked 10 October 2026).
Our verdict: MerchantWords is worth a look if keyword volumes are the one thing you need, especially across several marketplaces, and you would rather not pay for a full suite. Silver is cheap for one country but lacks Keyword Multiplier and regional data. If you also need product research, a suite gives you more for similar money, and MerchantWords’ own pages disagree about which marketplaces some tools cover.
This review draws on MerchantWords’ pricing page, FAQ and product pages, read on 10 October 2026. Where we describe what a feature does or how accurate it is, we’re reporting MerchantWords’ own documentation, and we say so.

MerchantWords pricing (checked 10 October 2026)
MerchantWords’ pricing page has a monthly and an annual toggle; annual billing gives “2 months FREE”.
| Plan | Monthly | Billed annually | Searches, users and coverage |
|---|---|---|---|
| Silver | $35 | $350 a year | 500 searches; 1 user; one country |
| Gold (“Best value”) | $79 | $790 a year | 1,000 searches; 2 users; one region |
| Platinum | $149 | $1,490 a year | Unlimited searches; 3 users monthly, 5 annually; all marketplaces |
| Enterprise | $749 a month, through sales | No annual option | Unlimited searches; 20 concurrent users |
Two details the cards leave out. They don’t say whether the 500 or 1,000 searches are per month or per billing period, and the annual cards show the same numbers. Collections, MerchantWords’ saved keyword lists, are capped at 10 on Silver, 100 on Gold, 1,000 on Platinum and 10,000 on Enterprise.
The “Risk-Free Guarantee” on MerchantWords’ pages promises that you can cancel at any time with no hidden fees, contracts or credit system. It doesn’t promise refunds. Payment is by Visa, Mastercard or American Express through Stripe, and MerchantWords says existing subscribers can keep their legacy plan and price.
What each MerchantWords plan includes
The pricing page’s comparison table shows what Silver leaves out:
- Every plan: the Classic Keyword Tool (monthly keywords, search volumes, seasonality and “depth”, MerchantWords’ popularity measure), Keyword Collections, the Keyword Vault (which MerchantWords says holds 1.6 billion keywords collected since 2012), ASIN Plus reverse ASIN lookups (marked “US Only”), Page 1 Products, price and performance metrics, and search history.
- From Gold: Keyword Multiplier, which finds related and complementary keywords, and regional data for North America, the EU or Asia/Australia.
- Platinum only: global data, which the table describes as “all 11 marketplaces”.
So Silver suits a seller in one marketplace who needs volumes and reverse ASIN for US products. Anyone who wants related-keyword expansion starts at Gold.
Where MerchantWords’ data comes from
MerchantWords’ FAQ says its keyword data “comes directly from Amazon’s search bar”, and that it continuously crawls search suggestions, product listings and ranking data. It is open about the limits of the volumes:
Treat the numbers as MerchantWords suggests: good for comparing keywords and spotting trends, not as exact counts. If you own a brand enrolled in Amazon Brand Registry, Amazon’s own Top Search Terms and Search Query Performance reports show first-party data for free.
Which marketplaces it covers
MerchantWords’ pages disagree. The FAQ lists 11 marketplaces: the US, UK, Canada, Germany, France, Italy, Spain, India, Japan, Australia and Mexico. The homepage shows 21 marketplace flags and a banner saying “ASIN Plus now supports all 21 marketplaces”, while the pricing table still labels ASIN Plus “US Only” and global data as “all 11 marketplaces”. If you sell outside the US, ask MerchantWords which tools cover your marketplace before you pay.
Other MerchantWords tools
MerchantWords says it has rebuilt the product “from the ground up”, and its products page, site menu and FAQ now describe more than keyword search:
- Product Tracker (marked new): daily keyword rank tracking for your listings.
- Emerging Trends: new search terms appearing on Amazon.
- Keyword Explorer: filter, edit, annotate and export a set of results.
- Bulk Search: many keywords or ASINs at once.
- Digital Shelf: how your products compare with competitors for chosen keywords.
- Buy Box Monitor: Buy Box and hijacker tracking.
- API and MCP: a separate API subscription for developers, with a free tier limited to 2 requests a minute; MerchantWords says every paid tool plan includes a personal MCP allowance for querying its data from an AI agent.
The pricing table doesn’t say which plans include the tracker, Digital Shelf or Buy Box Monitor, so check before you buy for them.
Is MerchantWords free?
No. MerchantWords’ pricing FAQ says “We do not offer free trials at this time”, and the pricing page lists only paid plans. You can cancel at any time, with no contract or cancellation fee, and keep access until the end of the billing period.
A few free things sit around the paid plans. The homepage’s “Risk-Free Guarantee” block has a “Test for free” link that opens a sample search for one ASIN. The separate API has a free tier limited to 2 requests a minute and a public demo key with “real data on a fixed set of demo terms”, but both are developer products rather than the keyword tool. And an older MerchantWords blog page titled “Free Reverse ASIN Keyword Tool for Amazon” ends by telling readers to upgrade to a paid plan to get ASIN Plus.
MerchantWords vs Jungle Scout
MerchantWords and Jungle Scout overlap only on keywords:
| Checked 10 October 2026 | MerchantWords | Jungle Scout |
|---|---|---|
| Entry price | Silver: $35 a month, or $350 a year | Starter: $49 a month, or $29 a month billed annually |
| Keyword allowance on that plan | 500 searches (period not stated) | 50 Keyword Scout searches a month |
| Product research | Not in its tool list | Product database, Opportunity Finder and a sales estimator on every plan |
| Rank tracking | Product Tracker (plans not stated) | From Growth Accelerator: 500 keywords |
| Trial or guarantee | No free trial | No free trial; 7-day money-back guarantee for new customers on regularly priced plans |
MerchantWords is built around keyword lookups: 500 searches on Silver, 1,000 on Gold and unlimited on Platinum. Jungle Scout caps Keyword Scout at 50 searches a month on Starter and 250 on Growth Accelerator, but it is the better buy if you are still choosing products, because every plan includes product research and sales estimates. Our Jungle Scout review and Jungle Scout pricing guide cover its plans.

Who MerchantWords is for
- Sellers in several marketplaces who need keyword volumes for each, without a full research suite (Gold for one region, Platinum for all).
- Listing writers and agencies who build keyword lists for clients and want Collections and Keyword Multiplier.
- Developers who want keyword data in their own tools through the API or MCP.
Who should skip MerchantWords
- Sellers still choosing a product. There is no product database or sales estimator; a suite such as Jungle Scout or Helium 10 fits better, and our best Amazon seller tools guide compares them by job.
- Anyone who needs exact volumes. MerchantWords says its numbers are estimates; brand owners get Amazon’s own data free.
- Sellers who want to try before paying. There is no free trial.
MerchantWords’ limitations
- No free trial, and the guarantee covers cancellation, not refunds.
- Silver is limited: one country, no Keyword Multiplier, no regional data.
- Marketplace claims conflict across the FAQ, homepage and pricing table.
- Search allowances have no stated period on the plan cards.
- Volumes are estimates, by MerchantWords’ own account.
- It is built around keywords: no product research, sales estimates, PPC or profit tools.
