Keyword Density Checker
Paste your text and see which words and phrases repeat, how often, and where the copy starts reading repetitively, measured live in your browser.
Your text
Keyword density is how often a word or phrase appears relative to the total word count, and reading it well is less about hitting a number than about catching copy that has quietly started repeating itself. This free checker counts single words, two-word phrases and three-word phrases, shows each one's count and density, and flags the terms that sit well above the rest. It is built for content writers, editors and SEOs who want prose that reads naturally and gets found, without padding toward an invented target.
How to use it
Paste your article or page copy
Drop your text into the box and the word, character, sentence and reading-time counts update live. Everything runs in your browser, so you can safely check drafts and client work without signing in.
Read the single, two and three-word tables
Switch between single words, two-word phrases and three-word phrases. Each row shows the raw count, the density as a percentage, and a bar for its share, sorted by how often it appears.
Set a target keyword and check the flags
Type a target term to see its exact-phrase count and whether it stands out or sits in line with the rest. Terms marked "repeats often" are a prompt to reread, not a number to chase.
Why it's useful
Phrases, not just single words
A single word repeating is often unavoidable: an article about running shoes will say shoes a lot. A whole phrase repeating verbatim is the real signal, usually the same sentence written three times with the words rearranged. Seeing two and three-word phrases catches what a single-word count misses.
Density read against length
The same fifteen occurrences mean nothing across two thousand words and everything across three hundred. The summary bar shows the total word count beside every density figure, so you read repetition in context instead of reacting to a percentage in isolation.
Nothing leaves your browser
The whole analysis runs client-side. Your text is never uploaded or stored, so unpublished posts, confidential briefs and client drafts stay on your machine while you edit them.
How to read these numbers
Density is not a ranking factor
Keyword density is not a ranking factor, and Google has never published a target. Any specific percentage you have seen quoted as optimal was invented by someone selling a tool, not measured in a search result. Density here is calculated the honest way: the term's occurrence count divided by the total word count, including common words, so you can check the arithmetic yourself and trust the figure rather than taking it on faith.
That means the goal is never to push a word to some magic number. Modern search understands synonyms, related terms and the overall topic of a page, so stuffing a single phrase in repeatedly does nothing for visibility and often makes the copy worse. Use density to understand your text, not to optimise against it. The useful question is not "is this keyword at two percent" but "does this page read like it was written for a person."
What the numbers are genuinely good for
Where these counts earn their keep is in catching text that reads badly. When the same phrase lands in four consecutive paragraphs, a reader notices long before any algorithm does, and that friction is what quietly loses attention. The flagged rows are a prompt to reread those sentences and decide, as an editor, whether the repetition is doing real work or just filling space that a fresh phrasing would fill better.
Two and three-word phrases are usually more revealing than single words. A single word repeating is often natural and expected; a whole phrase repeating verbatim tends to mean the same idea was written several times with the words shuffled. That is the pattern worth hunting, because it points to passages where the draft stalled and started circling, and tightening them almost always improves both readability and the page's chance of getting found.
Use the flags as a prompt, not a verdict
A term marked "repeats often" sits well above the average density of the other terms listed. That is a readability signal, not a threshold to fear. Sometimes a word repeats because it genuinely is the subject; sometimes it repeats because a paragraph is fighting itself. Only you can tell which, so treat the flag as a reason to look, then judge the sentence on how it reads.
Length changes everything
A term appearing fifteen times across two thousand words is unremarkable; the same fifteen occurrences in three hundred words is a paragraph at war with itself. Density only means something next to the word count it came from, which is why the summary bar keeps the total in view at all times. Read the two together and a figure that looked alarming in isolation often turns out to be perfectly normal, or the reverse.
Treat this whole tool as an editing aid rather than a scorecard. Write the page for the reader first, then run it through the checker to catch the places where a phrase has crept in once too often, trim those, and move on. A page that reads cleanly to a human is the one that holds attention, earns links and gets cited, and no density percentage will ever substitute for that.

Questions
What density measures, why there is no ideal percentage, and how to use the phrase tables.
There is no official target. Google has never published one, and any "ideal" percentage was invented to sell a tool. Write for the reader and use density to catch repetition that reads badly, not to hit a number.
It is the term's occurrence count divided by the total word count, including common words, expressed as a percentage. The count and the total are both shown so you can verify the figure yourself.
A single word repeating is often unavoidable. A whole phrase repeating verbatim usually means the same sentence was rewritten several times, which is the repetition most worth catching and fixing.
That term sits well above the average density of the others listed. It is a readability prompt to reread the passage, not a penalty or a limit you must stay under.
No. The analysis runs entirely in your browser; nothing is uploaded or stored, so you can check unpublished and confidential copy safely.
