What is Word Frequency & Keyword Density?

Word frequency measures how often each distinct word occurs in a body of text, while keyword density represents that frequency as a percentage of the total word count.

For copywriters, content creators, and SEO professionals, word frequency analysis is critical for detecting accidental keyword stuffing (repeating the same phrase unnaturally, which triggers Google search penalties), verifying brand message emphasis, and analyzing competitor content for key thematic topics.
