Practical guide
Free Keyword Density Checker for Words and Phrases
Measure how often words and phrases appear in pasted page copy. The report helps editors spot accidental repetition and missing topic language; it is not a target-percentage or ranking guarantee.
How to use this tool
  1. 1Paste the main visible copy from one page.
  2. 2Select single words, two-word phrases, or three-word phrases.
  3. 3Keep the stop-word filter on for a cleaner topical view.
  4. 4Review frequency in context and rewrite only where repetition hurts clarity.
How density is calculated

                    
Keyword density = keyword occurrences ÷ total words × 100

Example: 8 mentions in 800 words = 1% density

                
What the result means
  • There is no universal ideal keyword-density percentage.
  • Natural coverage of related concepts is more useful than repeating one exact phrase.
  • Menus, footers, and boilerplate can distort a whole-page count; analyze the main copy separately.
Frequently asked questions
What is a good keyword density?+
There is no fixed percentage that guarantees rankings. Use the report to detect unnatural repetition and make the page clearer for readers.
Does this tool upload my content?+
No. Keyword and phrase analysis runs locally in your browser.
Should I analyze one-, two-, or three-word phrases?+
Start with single words for broad themes, then use two- and three-word phrases to review repeated terminology and exact phrases.
