Frequently asked questions
Common questions about the keyword density checker.
What is a good keyword density?+
Roughly 0.5% to 3% reads naturally. There is no magic number - Google stopped counting repetitions years ago - but above about 3% the text starts to read as stuffed, which does cause problems.
How is density calculated?+
Occurrences multiplied by the number of words in the phrase, divided by the total word count. So a two-word phrase used five times in a 1,000-word page is 1%.
Why are common words missing from the list?+
Words like 'the', 'and' and 'of' are filtered out. They are always the most frequent words in any text and tell you nothing about the topic.
Does keyword density still matter for SEO?+
Not as a target to hit. It is useful as a check in two directions: that your main phrase appears at all, and that you have not repeated it so often the page reads badly.
