Keyword Density Checker
Paste text, or enter a URL, to see word/character counts and the top single-word and phrase frequencies — free, no signup required.
What this checks
This tool tokenizes your text (or a page's visible text, if you provide a URL) and counts how often each single word and short phrase appears, ignoring common stop words for single-word frequency. Density is calculated deterministically from the text you give it — there is no external ranking signal involved.
Frequently Asked Questions
- How is keyword density calculated?
- As the percentage of total words a given word or phrase makes up, computed from the actual page text or pasted text.
- Is there an ideal keyword density?
- No — there's no universal target percentage; this tool reports real frequency, not a pass/fail score.
- Can I check a URL instead of pasting text?
- Yes, enter a URL and the tool fetches the page and analyzes its visible text.
