WDF
WDF stands for Within Document Frequency and describes a weighted frequency of a term within one document. Unlike simple keyword density, WDF formulas may reduce the influence of excessive repetition logarithmically. The exact formula is not universally standardised and varies between analysis tools.
WDF can highlight unusual term distributions when comparing texts, but it is not a known Google ranking formula. Search engines assess language, meaning, context, quality, and many other signals far more broadly. Content should not be written to reach an assumed ideal WDF value; completeness, clarity, and search intent matter more.

Frequently asked questions
WDF stands for Within Document Frequency and weights how often a term occurs within a document.
No. Google has not confirmed an ideal WDF value. Content should be written for users and intent rather than a metric.
