Keyword density measures how often a term appears relative to the total number of words on a page. It's a quick way to check whether your content actually reflects the topic you're targeting — and whether you're leaning on a phrase so heavily that it reads as keyword stuffing. This checker tallies every word, strips common stopwords, and shows your top terms ranked by frequency and density percentage.
Use it to confirm your primary keyword shows up naturally, spot filler words you over-rely on, and compare the balance of related terms across a draft. Everything is calculated live in your browser as you type, so nothing is uploaded and you get instant feedback while editing.
Frequently asked questions
How is keyword density calculated?
Density is the number of times a word appears divided by the total word count, expressed as a percentage. A word used 5 times in a 500-word article has a density of 1.0%.
Why are words like 'the' and 'and' missing?
Common English stopwords are filtered out so the results focus on meaningful keywords rather than grammatical filler.
What's a good keyword density?
There's no magic number, but most SEOs aim for natural usage — roughly 0.5% to 2.5% for a primary keyword. Much higher can read as keyword stuffing.
Is my content sent to a server?
No. All analysis happens locally in your browser; your text never leaves your device.
