HOW IT WORKS
From a block of text to a ranked keyword list in seconds
Keyword density is how often a word or phrase appears, shown as a percentage of the total words. Checking it helps you confirm a page covers its topic without over-using any single term.
Paste your text
Drop in a draft, a published page's copy or any block of text. The counts update as you type, with nothing sent to a server.
Read the density table
See the top words and 2 and 3 word phrases ranked by frequency, each with its count and density percentage.
Adjust and rewrite
Spot a term that is over-used or a topic that is thin, then edit the copy and watch the numbers move in real time.
WHAT THIS TOOL SHOWS
Word and phrase frequency, counted the way SEOs read it
One pass gives you single words plus two and three word phrases, each ranked by count and density, with stop words filtered out so the results reflect your real topic.
Single word density
Every word ranked by how often it appears, with its density as a percentage of total words.
Two word phrases
Bigrams like "keyword density" surface the two word combinations your copy leans on most.
Three word phrases
Trigrams show the longer phrases and entities that matter for topical and long tail coverage.
Noise filtered out
Common words like the, and and of can be ignored, so the list shows the terms that actually describe the page.
Totals at a glance
Total words, unique words, character count and estimated reading time, all computed live.
Runs in your browser
Your text never leaves the page. Nothing is uploaded, logged or stored, so it is safe for unpublished drafts.
DENSITY DONE RIGHT
Use density as a signal, not a target to hit
There is no magic percentage that ranks a page. Density is most useful for catching two problems: a keyword repeated so often it reads as stuffing, or a topic mentioned so little the page barely covers it.

FAQ
Keyword density checker questions
What is a keyword density checker?
A keyword density checker counts how often each word and phrase appears in a piece of text and shows that count as a percentage of the total words. It helps you see which terms your content emphasises and spot over-use of any single keyword.
What is a good keyword density?
There is no exact target, but most SEOs keep a primary keyword in the region of 0.5 to 2 percent and write naturally. Densities well above that can read as keyword stuffing. Focus on covering the topic rather than hitting a number.
How is keyword density calculated?
Keyword density is the number of times a keyword appears divided by the total number of words, multiplied by 100. For a two or three word phrase, the count is the number of times that exact phrase appears in the text.
Is this keyword density checker free?
Yes. It is free with no signup, and it runs entirely in your browser, so nothing you paste is uploaded. To check keyword use across a whole site, download the free SiteAuditLint desktop app.
Does keyword density still matter for SEO?
Google does not rank on a density formula, so there is no magic percentage. Density is still a useful diagnostic for spotting thin coverage of a topic or accidental keyword stuffing, both of which can hurt a page.
What are stop words?
Stop words are common words like the, and, of and to that carry little topical meaning. This checker can ignore them so the results show the words and phrases that actually describe your content.
