# Keyword density checker

Count word and phrase frequency in text, with density as a percentage.

## How it works

Counts how often each word and phrase appears in a block of text, and expresses it as a percentage of total words. Two and three-word phrases are counted alongside single words, since that is where the useful patterns usually are.

Common function words — the, and, of, to — are filtered by default because they dominate any count and tell you nothing.

Worth saying plainly: there is no target density to hit. Keyword density as a ranking factor was obsolete by the mid-2010s, and modern search engines model meaning rather than counting repetitions. This is useful for spotting that you have accidentally used one phrase forty times, not for tuning a number upward.

> This tool runs entirely in your browser. Nothing you enter is sent to a server, logged or stored, and the page keeps working with the network disconnected.

## Common questions

### What is a good keyword density?

There is no good number. Density stopped being a meaningful ranking factor years ago, and writing to hit a percentage produces worse text than writing naturally.

### Why are common words excluded?

Because words like "the" and "of" top every count and reveal nothing. They can be included if you want the raw distribution.
