How is keyword density calculated?

Density is matching occurrences divided by the documented total word count, multiplied by 100. Phrase matches do not cross sentence or paragraph boundaries.

What is removed from pasted HTML?

Scripts, styles, metadata and markup are stripped locally before visible text is analyzed. The pasted HTML is treated as source text and is never executed.

Do stop-word filters change the total word count?

No. They affect the frequency table, not total words, reading time or Focus Keyword measurements. Custom exclusions and minimum occurrences behave the same way.

Is a high keyword density an SEO recommendation?

No. The tool reports repetition without assigning an ideal percentage. Natural relevance, usefulness and readability matter more than targeting a fixed density.

About Keyword Density Checker

Frequency data is most valuable when its denominator and filters are clear. This checker reports total and unique words, characters and reading time, then builds separate tables for single words, two-word sequences and three-word sequences. Case, numbers, common English stop words and custom exclusions can refine the table without rewriting the source metrics.

Focus Keywords are measured independently from those filters, making them useful for checking a planned phrase even when it contains excluded words. A local text preview highlights the selected phrase while capping only the rendered highlights, not the full count. TXT, DOCX and HTML extraction remains in the browser, and CSV or text reports preserve results for later editorial review.
