Is Keyword Density Checker free to use?

Yes. Keyword Density Checker is free, has no usage cap and does not require an account. There is no paid tier that unlocks extra output.

Does my data get uploaded to a server?

No. The tool is a JavaScript function that runs inside your browser tab. Nothing you paste or drop in is transmitted, logged or stored by us.

Do I need to create an account?

No account, no email address and no sign-in. Open the page and start working.

Does it work on a phone or tablet?

Yes. The interface is responsive and works in mobile Chrome, Safari, Edge, Firefox and Samsung Internet. You can also install Toolspea as an app from the browser menu.

Can I use the output commercially?

Yes. You keep every right you already had over the input, and we claim nothing over the output.

What is a good keyword density?

There is no correct number. Search engines stopped relying on raw term frequency long ago. Write naturally; use the tool to find repetition that reads badly rather than to hit a percentage.

Can high density hurt rankings?

Deliberately stuffing a term can trigger spam classification, and it always hurts readability. If a phrase appears far more often than a human writer would use it, rewrite the passage.

Should I include navigation text in the analysis?

No. Paste only the main content. Repeated site-wide chrome distorts the counts and tells you nothing about the page itself.

What is Keyword Density Checker?

Keyword Density Checker counts how often each word and two-word phrase appears in a text and expresses it as a percentage of total words. It is used to detect unintentional repetition, confirm that a page actually discusses its topic, and find over-optimised passages before publishing.

How to use it

1Paste the body copy, without navigation or footer text.
2Choose single words or two-word phrases.
3Read the ranked table of counts and percentages.
4Rewrite any term that dominates unnaturally.

Features

Single-word and bigram analysis
Stop-word filtering so the results are not dominated by 'the' and 'and'
Percentage of total words alongside raw counts

When people use it

Catching repetition

Drafts written quickly often lean on one phrase. Seeing it at four percent is a prompt to vary the language.

Checking topical coverage

If the terms you expect a subject-matter expert to use are absent, the page probably reads as thin to both readers and search engines.

Known limits

There is no target density. Modern ranking systems use semantic matching, not term counts; treat the output as an editing aid, not a score to hit.
