Free Amazon Keyword Tool: Build Your Keyword List and Campaign Structure

The free Amazon keyword tool below turns a few product terms into a complete, ready-to-load keyword plan. Type your seeds and descriptors and it writes out every seed and modifier combination in all three Amazon match types — Exact, Phrase, and Broad — merges in a negative-keyword list so you stop paying for junk clicks, and suggests a campaign structure you can copy straight to CSV. It runs entirely in your browser, needs no signup, and invents nothing: every line on screen is built from what you typed.

Most pages that rank for “free Amazon keyword tool” are just listicles pointing you at someone else’s software. This one gives you a working generator plus the operator workflow to turn its output into a real Sponsored Products campaign. One honest limit up front: it produces keyword variations and structure, not search volume — we will cover where to get real demand data below. Start with the tool, then read on.

What does this free Amazon keyword tool do?

It is a deterministic keyword-plan builder. You give it three things — seed product terms, descriptors, and terms to exclude — and it instantly returns a deduplicated keyword list expressed in Exact, Phrase, and Broad match, a merged negative-keyword list, a plain-language campaign structure, and a one-click CSV export. It does not connect to Amazon, does not require a login, and does not estimate search volume, bids, or competition, because those are numbers we would have to invent. Everything you see is a pure function of your inputs.

Concretely: the generator takes each seed on its own, then prefixes every descriptor to every seed to build long-tail variations, drops duplicates, and caps the result at 60 keywords so a big seed set stays usable. Each keyword is listed for all three Amazon match types — Broad, Phrase, and Exact — because on Amazon the match type is a separate field, not an inline symbol on the keyword. When you export, the CSV gives you a plain keyword-text column plus a Match Type column — the two fields Amazon’s Sponsored Products bulk sheet actually uses. The default example (seeds “yoga mat” and “exercise mat” with descriptors non slip, thick, 6mm, eco friendly) produces 10 keywords across 3 match types = 30 targets, so the table is populated the moment the page loads.

How do you turn one product into a full keyword list?

Give the tool two or three seed terms and four to six descriptors, and it does the multiplication for you. Seeds are the core nouns a shopper types — “yoga mat,” “exercise mat.” Descriptors are the attributes that signal buying intent — material, size, color, use case. The generator pairs every descriptor with every seed, so two seeds and four descriptors become ten distinct phrases, each one a more specific, higher-intent long-tail keyword than the bare seed alone.

The long-tail is where the leverage is. A shopper searching “non slip 6mm yoga mat” knows what they want and converts far better than one searching “yoga mat,” and those specific phrases usually cost less per click because fewer sellers bid on them. To get a strong list, pull your seeds from your product title and your competitors’ titles, and pull descriptors from your bullet points, material, size, and the problems your product solves. For the full research method behind choosing seeds — including reverse-ASIN and Brand Analytics techniques — see our complete Amazon keyword research guide.

Which match type should each keyword use — Exact, Phrase, or Broad?

The tool gives you all three for every keyword so you can choose per campaign, not per keyword in the abstract. Broad match reaches the most searches and is best for discovery; Exact match reaches only the specific phrase and is best for protecting proven winners; Phrase sits in between. A common, effective structure is to launch new keywords on Broad to find search terms cheaply, then graduate the ones that convert into a tightly bid Exact-match campaign. The table below is the decision at a glance.

A note on uploads: Amazon has no inline symbol notation for match types — it uses a separate Match Type field (broad, phrase, or exact) alongside the plain Keyword Text. That is exactly what the CSV export gives you — the plain keyword and its match type in two columns — so you paste it into Amazon’s Sponsored Products bulk sheet without hand-editing the keywords themselves.

Why does the tool add negative keywords automatically?

Because negative keywords are the fastest way to stop wasting ad spend, and every new campaign should launch with them. The tool merges the terms you type into the exclude box with a built-in list of 11 common junk modifiers — free, used, refurbished, wholesale, bulk lot, diy, how to, review, near me, replacement, and manual — that pull in browsers, price-shoppers, and researchers who rarely buy. You get a de-duplicated starter list you can apply from day one instead of discovering the waste in your search-term report a month later. Treat it as a starting point, not gospel: give it a quick read first, because a few of those defaults — used, refurbished, wholesale, bulk lot — are only junk if you don’t actually sell those; remove them if you do, and add the terms that are irrelevant to your specific product.

Add your own excludes too: competitor brand names you cannot fulfill demand for, incompatible sizes or variants, and use cases your product does not serve. Negatives are not set-and-forget — they are an ongoing discipline you feed from live data. Our guide to Amazon negative keywords covers negative match types (negative exact vs negative phrase) and how to mine your search-term report for the next batch.

How do you turn the export into a working Sponsored Products campaign?

The generator gives you the list; here is the operator workflow that turns it into performance. Start with a low-bid discovery campaign whose only job is to find which real search terms convert. You have two ways to run it, and they work well side by side. The first is a manual Broad-match campaign: load the keywords this tool generated, and Amazon matches them plus related terms, synonyms, and word-order variants. The second is an Auto-targeting campaign, which takes no keywords at all — you point it at your listing and Amazon decides what to match from your title, bullets, and backend terms, surfacing search terms you would never have thought to add. Apply the full negative list to whichever you launch immediately. After a couple of weeks of data, pull the search terms that actually produced sales and promote them into a separate Exact-match campaign with higher, deliberate bids — and add the wasteful terms you found as new negatives to every campaign.

The step most sellers get wrong is the harvest: you cannot see which generated terms convert without clean search-term and targeting data. This is where a dedicated analytics layer earns its place. WisePPC’s Search Terms and Targeting reports show, term by term, which of the keywords you generated here are driving orders versus burning budget — backed by the deep history WisePPC keeps beyond Amazon’s short native reporting window, up to 15 months of daily data once you connect your Amazon Ads account. From the Management page you make the calls yourself — add the winners as Exact-match targets and push the junk into negatives with bulk or inline edits. If you run your own AI, WisePPC is bring-your-own via MCP: connect your Claude, ChatGPT, or any MCP agent to your WisePPC data and it proposes the bid, budget, and negation changes for you to approve inside the platform. The human stays in the loop on every change. For the campaign-type context — when to reach for Sponsored Brands instead — see Sponsored Products vs Sponsored Brands.

How do you find search volume for these keywords?

You use a separate data source — and being clear about that is the honest part most tools skip. This generator produces variations, match types, and negatives, but it shows no search volume, because it has no access to Amazon’s search data and fabricating numbers would be worse than useless. To size demand for the keywords you generate, take the list to a tool that measures real searches.

Inside Seller Central, Amazon Brand Analytics (Search Query Performance and the Top Search Terms report) shows genuine, Amazon-native search frequency for brand-registered sellers, and Product Opportunity Explorer shows search volume and growth by niche. Outside Amazon, free autocomplete-based tools — Amazon’s own search-bar suggestions, or utilities that scrape them — reveal which of your long-tail phrases shoppers actually type, though they estimate rather than measure. The reliable workflow: generate structure here, validate volume in Brand Analytics or Product Opportunity Explorer, then launch and let real conversion data settle which terms deserve budget.

How is this different from other free Amazon keyword tools?

Most free “Amazon keyword tool” pages are directories: a list of ten other products, each with a signup wall. This page gives you a tool that runs immediately and a workflow that tells you what to do with its output — generate the list, structure it by match type, negate the junk, launch a discovery campaign, and promote the winners. That end-to-end path, not another list of links, is the difference.

WisePPC is an Amazon Ads management and analytics platform built by an Amazon Ads Verified Partner team, for sellers and agencies running Sponsored Products, Brands, Display, and TV across the US, UK, DE, and JP marketplaces. The generator is a taste of the approach we take inside the product: give operators exact, honest tools instead of black-box promises. When you are ready to see which of these keywords convert — and to size bids against your margin, which our primer on what counts as a good ACoS walks through — you can start a free 30-day trial with no credit card and get 15 months of daily history the moment you connect your Amazon Ads account.
