You do not need to spend hundreds of dollars on keyword research tools. In 2026, some of the most powerful free keyword research tools are available to anyone with an internet connection. This guide covers the best free options for Amazon sellers, Etsy shop owners, YouTube creators, and general SEO research.

Free Keyword Tools for Amazon Sellers

1. TagReveal (Free)

Best for: Extracting keywords from competitor Amazon URLs

TagReveal is a free keyword extractor that analyses any Amazon product URL and reveals the keyword strategy hidden in that listing. Paste a competitor's URL and instantly get primary keywords, long-tail phrases, and related terms categorised by product type. It detects whether the product is electronics, kitchen, fashion, health, or baby items and tailors the keywords accordingly. No signup, no credit card, works instantly.

2. Amazon Autocomplete

Best for: Finding real buyer search terms

Amazon's own search bar is one of the best keyword research tools available. Type your product into the search bar and look at the dropdown suggestions — these are real searches buyers make. Add a letter after your keyword to uncover even more variations. Completely free and always up to date.

3. Google Keyword Planner (Free)

Best for: Search volume data

Google Keyword Planner is free with a Google Ads account (no need to run ads). It shows search volume ranges for keywords and suggests related terms. While it shows Google search data rather than Amazon search data, there is significant overlap for product keywords.

Free Keyword Tools for Etsy Sellers

4. TagReveal (Free)

Best for: Competitor Etsy tag extraction

TagReveal detects Etsy listing types (SVG/digital file, art print, jewelry, clothing, handmade item, wedding digital) and generates precisely targeted keywords. For an Etsy art print listing, it generates art-print-specific keywords like "printable wall art instant download" and "300 dpi high resolution file" — not generic Etsy boilerplate.

5. Etsy Search Bar + eRank Free Tier

Best for: Etsy-specific keyword research

eRank offers a free tier that shows basic keyword data for Etsy including average monthly searches and competition levels. Combined with Etsy's own search bar autocomplete, the free tier gives you enough data to make informed keyword decisions without paying.

6. Marmalead Free Trial

Best for: Etsy keyword grading

Marmalead's free trial gives you limited but useful access to their Etsy keyword data. Use the trial strategically to research keywords for your most important listings, then rely on free methods for ongoing research.

Free Keyword Tools for YouTube Creators

7. TagReveal (Free)

Best for: Extracting keywords from competitor YouTube videos

TagReveal uses the YouTube oEmbed API to automatically fetch any video's title when you paste the URL, then extracts relevant keywords from the title content. For niche-specific videos about Etsy selling, Amazon FBA, passive income, or AI tools, it generates highly relevant YouTube SEO keywords without any manual input.

8. YouTube Autocomplete

Best for: Finding what YouTube viewers actually search for

Like Amazon, YouTube's search bar autocomplete is one of the most valuable free keyword tools available. Search your topic and note every suggestion. Then add letters (a, b, c...) after your keyword to reveal dozens more keyword ideas directly from YouTube's database.

9. TubeBuddy Free Tier

Best for: Basic YouTube keyword data

TubeBuddy's free browser extension shows keyword scores and competition data directly on YouTube. While the free tier is limited, it gives you enough information to evaluate whether a keyword is worth targeting before investing time in a video.

Free Tools for General SEO Research

10. Google Search Console (Free)

Best for: Discovering keywords you already rank for

If you have a website, Google Search Console is the single most valuable free tool available. It shows you exactly which keywords bring visitors to your site, your average position, and click-through rates. Use this data to identify keywords where you rank on page 2 — a little optimisation can move you to page 1 and dramatically increase traffic.

11. Ubersuggest Free Tier

Best for: Overview keyword data

Neil Patel's Ubersuggest offers 3 free searches per day showing search volume, competition, and keyword ideas. While limited, it is enough for targeted research on your most important keywords.
