If you’re a content creator on YouTube, marketer, or even a casual uploader wondering why some videos get buried while others get seen, you’ll know how crucial keywords are. You type a video title, description, tags—but unless you use the right keywords (terms people actually search), your video might never reach the right audience. What if you have a tool that extracts keywords or helps you find them fast—so your content gets discovered more easily?
In this article, we’ll explore the best YouTube keyword extractor tools of 2025—starting with our own YouTube Keywords Extractor on freetoolr.com, which is totally free and needs no sign-up. Then we’ll look at 9 other tools (free, freemium, premium) so you can compare, decide, and pick what works best for your channel. Whether you’re just getting started or trying to grow further, knowing which tool to lean on matters.
#1: Our Tool (Freetoolr.com)
Tool Name: YouTube Keywords Extractor
Link: https://freetoolr.com/youtube-keyword-extractor
Description
Suppose you uploaded a video last week, but it’s not getting views. You think maybe your title/tags/description weren’t optimised. With YouTube Keywords Extractor on Freetoolr, you just enter a video URL (yours or a competitor’s/public video), and the tool extracts the keywords used (tags, sometimes metadata) plus suggests related keyword ideas. This helps you see what people are targeting, what competitors are doing, and gives inspiration for your own keywords.
Another scenario: you’re planning your next video and want a list of keyword ideas around your topic (say “healthy breakfast recipes” or “study tips for board exams”). This tool helps by generating suggestions that match what viewers are actually typing/searching, to improve your title, tags, description, etc. The value is in saving time, avoiding guesswork, and making data-informed choices without needing expensive tools.
