About the Keyword Density Checker
Keyword density measures how often a word or phrase appears relative to the total number of words on a page. It is a simple, old-fashioned metric, but it is still useful as a diagnostic. A repeating word can reveal that a draft is leaning too hard on one term, or that a page has drifted away from the topic its title promises. This checker shows the top words and two-word phrases, their counts, and their density as a percentage.
Paste your content and the analysis updates as you type. The minimum length filter removes very short words that rarely carry meaning. The ignore stop words option removes common grammar words such as “the”, “and”, and “with”, so the remaining list reflects the actual subject matter. Two-word phrases give more context than single words: “domain name” is more informative than “domain” alone, and it can reveal whether a page is genuinely focused or just repeating a keyword.
Reading the results responsibly
There is no magic density percentage. Search engines do not publish a target, and writing to a number usually produces stiff, repetitive copy that readers dislike. Use the table to spot unintentional repetition, then rewrite for clarity. Density is also affected by page length: a keyword appearing five times in 200 words looks very different from five times in 2,000 words. The percentage accounts for that, but it cannot measure relevance, search intent, or authority. Export the data as CSV if you want to track a draft over time or compare several pages.
Frequently asked questions
What is a good keyword density?
Most natural writing lands somewhere around 0.5% to 2% for a primary term, but that is an observation, not a rule. Prioritise readability and topical completeness over hitting a percentage.
Does the tool count keyword variations?
No. It counts exact tokens after lowercasing, so “domain” and “domains” are separate. Use the phrase table and your own judgement to account for variations.
Is my content uploaded or saved?
No. All counting happens in your browser, and the text disappears when you close or refresh the page.
