Frequently asked questions

How do I find the most frequent keywords in a text?

Paste your text and the tool lists the most-used words with their count and density, ranked from most to least frequent. Use the slider to show 5 to 50 keywords and click Copy list to copy them as comma-separated text.

What is keyword density and what is a good percentage?

Keyword density is how often a word appears as a share of all counted words. There is no official ideal, and search engines do not reward hitting a target. A word repeated far more than natural writing would suggests is a sign of stuffing.

Are common words like the and and counted?

No. The tool ignores a built-in list of English stop words such as the, and, with and would, plus any word shorter than three letters. That keeps the results focused on meaningful terms. Density is calculated using the remaining words only.

Can I use this to check my blog post for SEO?

Yes, as a quick check. Paste the post and see whether your main topic word appears among the top results. It counts single words, not phrases, and does not judge search intent or competition, so treat it as a helpful gut check rather than a full SEO audit.

Does the keyword extractor support other languages?

It is built for English. It matches words made of the letters a to z and uses an English stop-word list, so accented characters and non-Latin scripts are split or ignored. For other languages results may be incomplete.

Does it find keyword phrases or only single words?

Only single words. Each word is counted on its own, in lowercase, so Apple and apple are grouped together. If you need phrases, look at your top single words and check how they appear together in your copy.

Is my data shared when using the Keyword Extractor?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the Keyword Extractor?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.
