Keyword Density Checker

See which words and phrases appear most often in a block of text.

About this tool

This counts how often each word and two-word phrase appears in a block of text and shows the most frequent ones with their density (occurrences as a percentage of total words) — a quick way to sanity-check whether your content actually emphasizes the topic you intended, or whether a term you meant to focus on barely appears.

Common filler words (the, and, a, to, of, and similar) are excluded from single-word results so the list reflects actual topical content rather than being dominated by function words that appear in any text regardless of subject.

Keyword density as a specific target percentage is outdated SEO advice — modern search engines evaluate topical relevance and content quality far more holistically than counting keyword occurrences, and deliberately stuffing a target density can make content read poorly without any ranking benefit. Use this as a sanity check for balance and emphasis, not a percentage to hit.

Frequently asked questions

What keyword density should I aim for?

There isn’t a meaningful target percentage — modern search engines don’t rank based on hitting a specific density, and writing to hit one usually just makes content read awkwardly. Use this tool to sanity-check emphasis, not as an optimization target.

Why are words like "the" and "and" excluded?

They’re common function words that appear in nearly all English text regardless of topic, so including them would just show a generic frequency list rather than anything about your specific content.

Does this check phrases longer than two words?

Yes — use the n-gram size dropdown to switch between 2-word and up to 7-word phrases, in addition to the single-word list shown alongside it.
