Keyword Density Checker

The keyword density checker counts how often each word and phrase appears in your text and shows the percentage of the total. It supports one-, two- and three-word phrases and can filter out common stop words so the results reflect meaningful terms.

How to use the Keyword Density Checker

  1. Paste the body copy of the page you want to analyse. Leave out navigation and boilerplate.
  2. Choose single words, or two- and three-word phrases to find repeated expressions.
  3. Keep stop-word filtering on so results are not dominated by "the" and "and".
  4. Review the table, then download it as CSV if you want to keep a record.

Example

Input
A 500-word article about online tools
Output
online tools   6   1.2%
browser        4   0.8%
convert        3   0.6%

Common use cases

  • Checking that a page actually covers the topic it targets.
  • Spotting over-optimisation where one phrase is repeated unnaturally often.
  • Finding filler words and crutch phrases to edit out.
  • Comparing your page against a competitor page you have pasted in.

Limitations and things to watch for

  • Keyword density is a descriptive statistic, not a ranking factor. There is no target percentage to hit, and search engines have not treated raw density as a quality signal for many years. Use it to spot repetition, not to chase a number.
  • The stop-word list covers common English function words only. Text in other languages should be analysed with the filter switched off.
  • Words are matched after lowercasing and stripping punctuation, so "run" and "running" are counted separately.

Frequently asked questions

What is a good keyword density?
There is no correct figure. Search engines stopped rewarding density targets long ago, and writing to hit a percentage produces worse copy. Treat anything that stands far above the rest of the table as a prompt to check whether the repetition reads naturally.
Does it count two- and three-word phrases?
Yes. Switch the phrase length option to two or three words to see which multi-word expressions recur, which is usually more informative than single-word counts.
What are stop words?
Very common function words such as "the", "and", "of" and "to". They dominate any frequency count without saying anything about the topic, so they are filtered out by default.
Can I export the results?
Yes. The download button saves the table as a CSV file you can open in a spreadsheet.
