Paste an article, a landing page, or a draft and see which words and phrases you actually repeat, and how often. The checker reports density for single words, two-word phrases, and three-word phrases, filters out stop words like 'the' and 'of', and grades a focus keyword against the 0.5–2.5% range most on-page guides recommend. Nothing is uploaded — the analysis runs in your browser.
How it works
- 1 Paste your text Drop in the body copy of the page you're optimising. Headings and paragraphs are fine; skip navigation and footer boilerplate, since those repeat sitewide and will skew the counts.
- 2 Set a focus keyword Type the phrase you want the page to rank for. The tool counts exact matches and tells you whether the density is under-used, in the natural range, or heavy enough to read as stuffing.
- 3 Read the phrase tabs Switch between 1-word, 2-word, and 3-word views. Two- and three-word phrases usually carry the useful signal — they show which topics the page really covers.
- 4 Export or edit Copy the active table as CSV for a content brief, or edit your draft and watch the numbers change as you type.

Frequently asked questions
- What is a good keyword density?
- Between 0.5% and 2.5% for the main keyword is the range most on-page SEO guides settle on, and it's what this tool grades against. There is no official target — Google has never published one, and John Mueller has said more than once that keyword density is not a ranking factor. Treat the number as a writing check: below 0.5% the page may not be clearly about the topic, above 2.5% it usually starts to read badly.
- How is the density percentage calculated?
- Count divided by the number of positions a phrase of that length could occupy, times 100. For single words that is simply count / total words. For a two-word phrase the denominator is total words minus one, and for three words it is total words minus two — so densities stay comparable across the three tabs instead of shrinking artificially for longer phrases.
- What does the stop-word filter remove?
- Single stop words (the, and, of, a, in, plus для, что, как and around 250 more across English and Russian) are hidden, and multi-word phrases are dropped when they start or end with one. That keeps "search engine optimization" but throws away "of the page" and "the search". The total word count still includes stop words, so the density percentages do not inflate.
- Does keyword density still matter for SEO in 2026?
- Not as a ranking lever. Density was a real signal in the early 2000s, and Google's Panda update in 2011 was aimed squarely at pages that gamed it. What the number is still good for is diagnosis: it shows at a glance whether a 1,500-word article mentions its main topic four times or forty, and the three-word phrase list is a fast way to spot repetitive filler you did not notice while writing.
- Can I check the density of a competitor's page?
- Yes — copy the visible text of the page (select the article body, not the whole browser tab) and paste it in. You will see which phrases they lean on. Leave out navigation and footer if you can; sitewide boilerplate repeats on every page and crowds the top of the single-word table.
- Does the tool handle Russian and other languages?
- Yes. Word splitting uses Unicode letter classes, so Cyrillic, Greek, accented Latin, and mixed-language text all tokenise correctly, and the built-in stop-word list covers English and Russian. One caveat for inflected languages: a keyword is spread across its forms, so "плотность", "плотности" and "плотностью" count as three separate words.
- Is my text sent to a server?
- No. The whole analysis is plain JavaScript running on your device. Nothing is uploaded, logged, or stored, which matters if you are checking an unpublished draft or client copy under NDA.
