Keyword Density Checker
Keyword Density Checker
See which words and phrases dominate your text, with counts and percentage density — the honest picture of what your page is really about.
Top single words
Top 2-word phrases
Top 3-word phrases
This tool is also a word frequency counter — paste any text and see how often each word appears.
Keyword density is the percentage of a text that a particular word or phrase makes up. If "coffee beans" appears twenty times in a thousand-word article, its density is about two percent. Writers and website owners check it for two opposite reasons: to make sure an important term appears often enough that readers (and search engines) grasp the topic, and to make sure it does not appear so often that the text reads like it was written by a robot chanting the same phrase.
This checker analyses your actual words. It reports the fifteen most frequent single words, and the ten most frequent two-word and three-word phrases, each with a count and a density. Phrase results are often the most revealing: they show the combinations you return to again and again, which may be your intended topic — or a habit you did not know you had. You can also enter a focus keyword and get its exact count and density on its own line.
A word of honest SEO advice: there is no magic density that ranks a page. Modern search engines understand topics, synonyms, and intent, and pages stuffed to a target percentage read badly and can be penalised. Use this tool as a sanity check — is my key term present and natural? am I accidentally repeating one phrase twenty times? — and then write for the reader.
The analysis runs entirely in your browser; your draft is never uploaded.

Frequently asked questions
What density should I aim for?
There is no proven ideal number. As a rough comfort zone, a main keyword around one to two percent reads naturally in most articles, while anything climbing past three percent usually starts to sound forced. Topic coverage and readability matter far more than the exact figure.
Are small words like "the" and "and" counted?
Yes — the single-word table counts every word, so common function words will top it. That is honest data; scan past them to the meaningful words just below, and rely on the two- and three-word phrase tables, where stopwords matter less.
How are words identified?
Text is lowercased and split into words made of letters and numbers, keeping internal apostrophes and hyphens. "Well-known" counts as one word and "don't" as one word. Densities for phrases are calculated against the number of possible phrase positions in the text.
Is my text private?
Yes. The counting happens locally in your browser. Your draft never leaves your device.
Is this a word frequency counter?
Yes — the Keyword Density Checker counts every word in your text and shows each word's frequency and percentage, so writers and students can check repetition at a glance.
