How to Use This Tool
Paste your article or content into the text box, then enter the keyword or keyphrase you're targeting. Every number — total words, unique words, sentence count, keyword occurrences, and density — recalculates instantly as you type or edit. Toggle the stop-word checkbox to switch the frequency table between raw word counts and a view that filters out common connecting words.
How It Works
The tool splits your text into individual words, then searches for your exact keyword or keyphrase as a contiguous sequence of words (so a two-word phrase only counts when both words appear together, in order). Density is calculated as the number of keyword occurrences divided by the total word count, multiplied by 100. The frequency table separately tallies how often every word appears, optionally excluding a built-in list of common English stop words like "the," "and," and "of."
Why This Tool Is Useful for SEO
Keyword density gives you a quick, objective read on how heavily a piece of content emphasizes a particular term — useful for checking that a target keyword appears often enough to be topically clear, without being repeated so much that the writing feels unnatural. The frequency table also surfaces words you're repeating unintentionally, which can be a sign of thin variation in your writing.
Best Practices
There's no single "correct" keyword density that guarantees better rankings — modern search engines evaluate relevance and quality far beyond a simple percentage. Use this tool as a sanity check rather than a target to hit: if your primary keyword doesn't appear at all, that's worth noticing; if it appears in nearly every sentence, that's usually a sign to rewrite for natural variation instead.
Frequently Asked Questions
Does a higher keyword density mean better SEO?
No. Search engines use far more sophisticated methods than keyword counting to judge relevance, and overly high density can look like keyword stuffing, which is generally discouraged.
How is density calculated for multi-word phrases?
The tool looks for your exact phrase as consecutive words in the text, then divides the number of matches by the total word count of the entire text, multiplied by 100.
Can I check density without excluding stop words?
Yes — uncheck the stop-word box to see the frequency table for every word, including common connecting words like "the" and "and."
