What keyword density measures

Density describes how often one known target occurs relative to the analyzed word total. It does not measure relevance, search demand, difficulty, or content quality.

Exact matching and boundaries

A word matches only the same normalized token. Phrase words must be consecutive and cannot cross punctuation, new lines, URLs, emails, or excluded numbers. Technical terms such as C++, C#, Node.js, and .NET remain distinct.

Use the number descriptively

There is no universal ideal percentage. Compare drafts or check whether required terms occur, then judge repetition in context. Readability and usefulness matter more than reaching a fixed number.

Choose the right text tool

Use this checker for known targets, Keyword Extractor to discover recurring terms, or Word Frequency Counter for a complete word census. This analysis runs locally in your browser.

Frequently asked questions

It counts exact occurrences of each word or phrase you enter, then divides that count by the total analyzed word count and multiplies by 100.
