Free keyword tools usually offer a limited number of searches each day, partial volume data and suggestions based on Amazon’s autocomplete. That is enough to build a first keyword list for a new listing. However, for a competitive launch, you will want reverse-ASIN data that free plans often restrict.
Start with Amazon itself. The search bar suggests real phrases, and the “customers also searched” sections reveal related terms. In addition, your own Sponsored Products search term report shows the exact phrases that led to clicks and sales.
A free keyword workflow
First, collect autocomplete phrases for your main product terms. Next, run them through a free tool to estimate relative volume. Then group them by intent and place the strongest phrases in the title and bullets. Finally, add the rest to backend search terms and test the top ones in an automatic campaign.
Mistakes to avoid
To begin with, don’t copy a competitor’s keywords blindly; they may sell a different variant. Also avoid stuffing the title, since Amazon limits length and readability matters. Finally, revisit your list after a month of ad data, because real search terms beat estimates.
How we ranked them
Each tool is scored out of 100: results and case studies (40%), specialty fit (25%), pricing transparency (20%) and verified reviews (15%). The score sets the editorial order. Sponsored spots are sold separately and never change it.
Write down the two or three jobs the tool must do every week, and test those first in the free trial.
Check the integrations you rely on (Amazon, Shopify, TikTok Shop, your email and analytics tools).
Price the plan you will actually need in six months, not the entry plan.
Look at how data gets in and out: exports, API access and what you keep if you cancel.
Read recent reviews for support quality and how often the product ships updates.
