📊 Keyword Density Checker
Analyze word frequency, keyword density, n-grams, and stuffing risk. Density is a diagnostic — not a ranking factor by itself.
SEO guidance
Use this to spot repetition and missing topic coverage. Do not chase an exact keyword-density percentage; write for search intent, entities, examples, and helpful answers.
Why it is useful
It helps writers and SEOs spot repetition, missing topics, stuffing, and content focus issues before publishing.
How it works
The browser tokenizes text, counts repeated words or phrases, and displays frequency percentages.
Best input
Paste the final body copy without navigation, footer, or unrelated boilerplate.
SEO tip
Use density as a smell check, not a target. Helpful content beats mechanical keyword repetition.
Privacy note
Text analysis happens locally in your browser.
Important limitation
Keyword density is not a ranking formula and can encourage poor writing if treated as a strict score.
Quick answers
What density is best?
There is no universal ideal percentage.
Can this improve rankings?
It can reveal repetition, but rankings depend on usefulness, intent, links, technical quality, and competition.
