Formula
Keyword density = exact case-insensitive whole-phrase occurrences ÷ word count × 100.
Example
Two occurrences in a 10-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
This is a simple phrase-frequency estimate, not a search-engine ranking or relevance score. Detailed content, accessibility and edge-case review remains ongoing.
