What Keyword Density Checker does
Keyword Density Checker analyzes a block of text and reports how often each word and phrase repeats, broken down into single words, two-word phrases and three-word phrases. It's the fastest way to spot whether a page leans too hard on one phrase — or barely uses it at all.
Everything is calculated in your browser the moment you select Analyze. Nothing is uploaded, which makes it safe to paste drafts that haven't been published yet.
How to check keyword density
- Paste the page content you want to analyze into the text box.
- Select Analyze.
- Review the three tables: the most repeated single words, two-word phrases, and three-word phrases, each with a count and percentage of the total text.
What counts as a stop word
Common connecting words — "the", "and", "is", "with", and similar — are filtered out of the single-word table so the results surface meaningful terms rather than a list dominated by function words. Two- and three-word phrases are built from the raw, unfiltered text, which is where genuinely repeated keyword phrases tend to show up clearly.
Using the results
There's no single "correct" density to aim for — modern search engines read for topical coverage, not a target percentage. Use the breakdown as a diagnostic: a phrase that dominates the top of every table is worth varying with synonyms, while a target phrase that barely appears at all may be worth working in more naturally.
