Formula
Keyword density = whole-phrase occurrences ÷ word count × 100.
Example
Two occurrences in a ten-word passage produce an estimated density of 20%.
Prepare your inputs
Enter text and a nonempty word or phrase. Matching is case-insensitive with letter/number boundaries.
Understand the result
Frequency is descriptive, not a recommended keyword target or ranking score. Repeating a phrase to increase this number can make writing worse.
About this version
This page uses a shared calculation method. Industry and country labels provide a browsing context; they do not change the formula or imply specialist or local regulatory validation. Currency labels do not perform currency conversion.
Limitations and assumptions
General-purpose estimate only. It does not apply country-specific tax rates, statutory payroll rules, accounting standards, or legal requirements. Verify local assumptions before business use.
