Amazon keyword research tool

The Amazon keyword research tool for print on demand sellers

Most Amazon keyword tools cover every product on the site and start from an ASIN you already sell. This one is for printed shirts and starts from a niche. Type retired teacher, gym dad or anything else, and Trendlytic pulls the phrases from the shirts selling best on Amazon US, adds what shoppers type, and counts the results behind each.

“At first, I didn’t really understand the difference between the different rankings, especially Rising. But after using Trendlytic more and filling my store with designs based on Rising niches, I started seeing a really noticeable increase in sales. Another feature I love is Generate Listing. Whenever I find a niche or design I like, I can create something unique and original from it. This helped me avoid the copyright issues I used to face before. I highly recommend Trendlytic.”

Features

What you get

A shopper on Amazon only ever sees listings that match the words they typed, so keyword work decides whether your shirt is in the race at all. The big seller suites answer that for every category, with modelled search volumes and lookups built around ASINs. A print-on-demand seller usually begins somewhere else: no product yet, only an idea and a blank canvas. You want to know which words carry the shirts that sell in that idea, which of those words are already buried under tens of thousands of results, and which still leave room. Trendlytic answers that before you open your design software, and the phrases serve you the same way whether you list through Merch on Demand or through Seller Central with a print partner.

Starts from a niche

No ASIN and no existing product needed. A word or two is enough, which suits a seller still deciding what to design.

Words the sellers already rank with

Up to 30 of the top shirts on Amazon US are read for your niche, and their titles are broken into the phrases that recur, weighted toward the shirts placed highest.

A real count behind every phrase

Each phrase goes to Amazon with a US delivery address. You get the number Amazon prints, not a modelled estimate.

Great, Good, Fair or Weak at a glance

Opportunity sums up demand against crowding, and the filters cut the table down to the best openings, the emptiest phrases or the ones on the rise.

Fits Merch and Seller Central

Use the phrases in a Merch title and two bullets, or in a Seller Central title, five bullets and the backend search terms field.

Protected names flagged early

Before a phrase reaches your listing it is compared with names people own, and a click on TM asks the USPTO's register directly.

TM©

And the designs that were never yours to print are marked

When a result leans on a known brand, a character or a famous person, it arrives with a TM or copyright badge on the card. You see it while you are choosing, not after a takedown. A first filter, not legal advice.

How it works

  1. 1

    Pick Amazon US, enter a niche

    It takes about a minute and uses one credit.

  2. 2

    Sort out the openings

    Filter to Best opportunities, then look at the shopper phrases for the same niche and note how the counts differ.

  3. 3

    Run your shortlist

    Look each phrase up in the USPTO, then place the strongest early in your title and the rest in your bullets.

Frequently asked questions

How does the 3-day free trial work?

Every plan starts with 3 days free. Starting it charges $1 to check the card is real, and that $1 is not refunded. The plan price itself is only billed when the trial ends, and cancelling before then from Manage Plan means it is never charged.

I haven't sold anything yet. Is Trendlytic for me?

Yes. A search needs no shop and no sales history: type an idea and you see what already sells for it on Etsy, Redbubble, TeePublic and Amazon US, how crowded each one is, and a plain verdict. Start with the marketplace you plan to sell on. If you are not ready for a trial, the free tools at /tools need no account.

What is the best Amazon keyword research tool for print on demand?

It depends on what you sell. For a catalog of physical products with PPC to manage, Helium 10 and Jungle Scout are the usual picks. If you sell printed shirts and want to start from a niche, Trendlytic is built for that, and it is ours, so weigh that when you read this. Merch Titans and Merch Informer also serve shirt sellers.

Does this work for products other than shirts?

Only partly. The keyword table comes from best-selling Amazon US shirts, so it suits t-shirts and similar printed apparel. AI ideas can suggest and measure hoodie, tote bag and mug phrases in the same niche. If you sell kitchenware, supplements or anything unprinted, a general suite will serve you better.

Can I use it if I sell through Seller Central, not Merch on Demand?

Yes. The phrases come from what buyers see on Amazon, so they do not depend on how your shirt is fulfilled. Seller Central simply gives you more room: a title, five bullets and a backend search terms field limited to 250 bytes, which is a good home for the phrases that did not fit anywhere else.

Why are there no monthly search volumes?

Amazon does not publish them, so any monthly figure from an outside tool is a model. We would rather show what can be read: the results Amazon prints for a phrase, the phrases its own search box suggests, and a Google trend line when Google has enough data.

How many keywords does one search return?

It depends on the niche. retired teacher gave 22 phrases from best sellers and 18 more from shoppers and AI ideas. camping, a far broader word, gave 4 and 38. Narrow niches tend to give a fuller best-seller table, because their shirts share more specific wording.

Is there a free Amazon keyword tool I can try first?

Yes. Our free keyword generator takes a niche with no account, opens three Amazon US suggestions with their result counts, and tells you how many more are waiting behind them. The best sellers' phrases, opportunity ratings and trademark marks are part of the paid Keyword Research.

What does each search cost?

One credit, whichever marketplaces you tick. Plans start at $19.99 a month and include the 1,000 top winning designs of the day in Best Design Instant as well.
