About the Keyword Density Checker
The Keyword Density Checker counts how often each word — or each two- or three-word phrase — appears in your content and shows the most frequent ones with a count and a percentage. The percentage is that term’s share of the total words in the text. For single words you can tick “ignore common words”, which skips roughly forty everyday stopwords like “the”, “and” and “of”, plus anything under three letters, so the list reflects what the piece is actually about rather than filler. That stopword filter applies to single words only; two- and three-word phrases are counted exactly as written.
It is handy for spotting when you have leaned too hard on one term, checking that your intended topic actually shows up, or comparing drafts against each other. It all runs in your browser, so your content is never uploaded.
One honest caveat: keyword density is a weak, dated SEO signal. Modern search engines rank on relevance, intent and quality, not on hitting a magic percentage, and stuffing a keyword to raise its density tends to hurt more than it helps. Treat this as a writing-awareness tool, not a ranking dial. Pair it with the readability checker or a word counter.
Frequently asked questions
What is a good keyword density?
There is no target worth chasing. Keyword density is an outdated signal; search engines rank on relevance and quality, not a percentage. Write naturally for readers and use this tool only to catch accidental over-repetition.
Why are common words missing from my results?
When “ignore common words” is ticked, single-word counts skip roughly forty everyday stopwords and any word shorter than three letters, so the list surfaces meaningful terms. This filter applies to single-word mode only.
Are two- and three-word phrases filtered too?
No. The stopword filter runs only in single-word mode. Phrases of two or three words are counted exactly as they appear, including any common words inside them.
What does the percentage mean?
It is that word or phrase’s share of the total number of words in your text — its count divided by the total word count. It is not a comparison against other pages or any benchmark.
Does my content leave my browser?
No. All counting happens locally in your browser, so nothing you paste is uploaded or stored.
