Keyword Density Checker

See which words and phrases dominate your text, with a frequency count and a density figure for one-, two- and three-word phrases. Track a target keyword to check it appears often enough — and not too often.

Frequency and density are the same table

The Uses column is a word frequency count: how many times each word or phrase appears. The Density column expresses the same number as a share of the total word count. Frequency tells you what you repeat; density tells you how heavily, relative to the length of the piece.

Which one you want depends on the job. For editing — finding the crutch words, checking a translation is consistent, seeing what a speech is really about — read the frequency column and leave the single-word view selected. For SEO work, density is the figure people quote, though it is worth reading why it stopped being a ranking factor before treating it as a target.

How to read the table

The table is sorted by use, so the top row is the term your text leans on hardest. Two things are usually worth acting on.

A term far above the rest. If your main phrase appears three times as often as anything else, the writing probably repeats itself. Replacing some instances with pronouns or synonyms almost always reads better.

A missing term. If the phrase you are writing about does not appear in the top ten, the article may be circling its subject without ever naming it — a genuine problem for both readers and search engines. Enter it in the target keyword field to see the exact count.

A realistic way to use density

  1. Write the piece without thinking about density at all.
  2. Paste it here and look at the one-word list. Does it describe the subject?
  3. Switch to two- and three-word phrases. These reveal the phrasings you repeat without noticing.
  4. Fix the outliers: one dominant term, or an important term that is absent.
  5. Check the readability afterwards, since replacing words changes how it reads.

Writing to hit a density number produces worse text than writing for a reader and then checking the number. Full reasoning inwhat is keyword density.

Frequently asked questions

What is keyword density?
The number of times a word or phrase appears divided by the total number of words, shown as a percentage. A term used 15 times in a 1,500-word article has a density of 1%.
What is a good keyword density?
There is no target that search engines reward. Most well-written pages land between 0.5% and 2% for their main topic simply by being about that topic. Treat anything consistently above 3% as a prompt to read the text aloud — it usually sounds repetitive before it looks manipulative.
Does keyword density still matter for SEO?
Not as a ranking factor in its own right. Search engines have used semantic understanding rather than term frequency for well over a decade. It is still a useful editing signal: it tells you what your page is actually about, and whether one phrase has taken over.
How is density calculated for phrases?
The count of the phrase divided by the total word count, the same denominator used for single words. That means a two-word phrase will always show a lower density than either of its words on their own, which is expected rather than a fault.
Why are words like “the” and “of” missing?
Common function words are filtered out by default so the list reflects your subject. Switch “Ignore common words” off to include every word.
