How to Find the Best Keywords for Your YouTube Videos (Free Methods)

Picking the right keyword before you film is one of the highest-leverage things a YouTube creator can do. A great video with the wrong title can sit at a few hundred views; a mediocre video on the right search term can pull in views for years. Here's how to find keywords worth targeting, without paying for an expensive SEO suite.

1. Start with YouTube's own autocomplete

Type a broad topic into YouTube's search bar and look at what it suggests before you finish typing. Those suggestions aren't random — they're drawn from real searches, weighted toward what's currently popular. This is the single most reliable free signal you have, because it comes directly from the platform you're trying to rank on, not a third-party estimate.

Go broad first ("home workout"), then narrow ("home workout no equipment", "home workout for beginners") to see how the suggestions branch. Each branch is a potential video idea with built-in search intent.

2. Look at what's already ranking for that keyword

Before committing to a topic, search it and look at the top 10 results. Ask three questions:

• How many views do the top videos have, relative to their channel's size? A video from a small channel with outsized views suggests the keyword itself is driving traffic, not just channel authority.
• How recent are the top results? If the top 10 are all 3+ years old, the topic may be evergreen but under-served — a real opportunity. If they're all from the last week, you're likely competing with a trending news cycle.
• What's missing? Read titles and skim a couple of videos. Gaps (an angle nobody's covered, a more recent update, a clearer explanation) are where you can realistically outrank established channels.

3. Check search volume signals, carefully

YouTube doesn't publish an official "search volume" number the way Google Ads does for web search. Any number you see representing YouTube search volume — including on tools like ours — is an estimate built from proxies (related video view counts, tag frequency, or general web search trend data), not a direct measurement. Use these numbers directionally (this topic seems bigger than that one) rather than as precise forecasts.

4. Mine trending and rising topics for timing

Some keywords are evergreen (searched steadily year-round); others spike around events, holidays, or news cycles. A rising keyword can be a great opportunity if you can publish quickly — but it also decays fast once the moment passes. Checking what's currently trending in your niche's country/region helps you decide whether to rush a timely video or invest in a slower, evergreen one.

5. Validate with a quick competition check

Once you have a shortlist, do a rough competition check: pull up the current top-ranking videos for the exact phrase and look at their combined view count, upload frequency, and engagement rate (likes + comments relative to views). A keyword with a handful of competing videos and inconsistent engagement is usually easier to break into than one dominated by a handful of massive, highly-engaged uploads.

Put it together

In practice: brainstorm from autocomplete, sanity-check against what's already ranking, treat volume numbers as directional, watch for timely opportunities in trending data, and finish with a competition gut-check before you hit record.
