Common questions

Is this free?

Yes. A few videos a day need no account, and signing in with Google raises the limit.

Why does keyword density matter for YouTube?

YouTube reads captions to understand a video. Saying your target phrase naturally in the video, not only in the title, helps it understand what the video is about.

What is keyword density?

How much of the transcript a phrase makes up: its count times its length in words, divided by the total words.

Can I include common words?

Yes. Untick 'Ignore common words' to count everything.

Does it work in other languages?

Yes. Counting works in any language; the common-word filter is English only.
