Frequently asked questions
Keyword density is how often a word or phrase appears divided by the total number of words, shown as a percentage. For example, a keyword that appears 5 times in a 500-word article has a density of 1%. This tool counts every word, then ranks terms by frequency and density.
There is no official target. Most SEO guidance suggests writing naturally and keeping any single keyword well under a few percent so the text doesn't read as spam. Search engines reward content that reads for humans, so use this checker to spot accidental over-use rather than to hit a magic number.
Function words (the, and, of, to…) usually top the raw frequency list but carry no SEO signal. Turning on "Ignore common words" hides them so the meaningful keywords and phrases rise to the top. The density percentages still use the full word count as the denominator, so they stay accurate.
