How it works

    
    
      
  1. Paste the text and enter the word or phrase to measure.
    2. 
      
  2. Press Check density. Matching ignores letter case and counts non-overlapping occurrences.
    3. 
      
  3. Density is phrase occurrences divided by the number of words, shown as a percentage.
    4. 
    


    
Examples

    
    
      
  • The phrase "free tools" twice in a 100-word paragraph is 2%.
    • 
      
  • A missing phrase returns 0 matches and 0% density.
    • 
      
  • Matching treats "SEO" and "seo" as the same phrase.
    • 
    


    
Frequently asked questions

    

  

    Is a higher density better?
    
Not by itself. This only reports frequency. Readable copy usually mentions a topic naturally instead of repeating a phrase in every sentence.

  

  

    How are words counted?
    
Words are sequences separated by whitespace. The phrase count uses a case-insensitive search and does not overlap itself.

  

  

    Is the copy uploaded for analysis?
    
No. The count runs in your browser and is not stored.
