How Keyword Density Checking Works
Keyword density
Measures how often a word or phrase appears in text.
Frequency
Counts the number of occurrences.
Density percentage
Converts frequency into a percentage of total words.
Phrase analysis
Helps spot repeated 2-word and 3-word patterns.
Editing signal
Density is only one small content quality signal.
Word Count, Keyword Frequency, and Density Explained
Word count
The total number of counted words in the text.
Unique words
Shows vocabulary variety and repeated terms.
Keyword frequency
How many times a keyword appears.
Phrase density
Checks repeated multi-word terms.
Stop-word filtering
Removes common words from top-word lists.
Match modes
Whole-word and partial matching can produce different results.
SEO, Readability, and Keyword Stuffing Notes
Not a magic formula
Keyword density does not guarantee rankings.
Search intent
Helpful content should match what readers are trying to accomplish.
Readability
Repeating a keyword too often can hurt flow.
Keyword stuffing
Excessive repetition can make content look spammy.
Related terms
Synonyms, headings, and clear structure matter.
Editing signal
Use density as guidance, not a strict target.
Common Keyword Density Examples
5 in 500
A keyword appearing 5 times in 500 words has 1% density.
10 in 1,000
A keyword appearing 10 times in 1,000 words also has 1% density.
20 in 500
A keyword appearing 20 times in 500 words has 4% density.
Whole-word match
“SEO” matches SEO, but not necessarily “seoul”.
Partial match
Partial mode can match inside longer words or phrases.
Short text
Short drafts can make density percentages look inflated.
