Keyword Density Checker

Keyword density is how often a word or phrase appears relative to the total word count, expressed as a percentage: a term used 5 times in a 500-word page has a density of 1%. This tool computes it for single words and for two- and three-word phrases, so you can see what your content actually emphasises.

There is no magic number, and Google has said as much — write naturally for the reader. As a rough smell test, a single content word sitting above about 4% often reads as forced, which is why this tool flags it. Aim for your main topic to appear enough to be clearly on-topic, not to hit a target percentage.

Keyword stuffing is repeating a term unnaturally often to try to manipulate rankings — it reads badly and can be penalised. The over-optimization flag here catches the most common sign of it: one word dominating the density table. If a term is flagged, the fix is usually to rephrase with synonyms and vary your sentences, not to delete every mention.

Words like “the”, “and” and “of” are the most frequent in any English text but carry no topical meaning, so left in they crowd out the words you actually care about. Turning on stop-word filtering hides them from the single-word table and skips phrases made entirely of them, leaving a table that reflects your real subject matter.

This tool works on text you paste, by design — it never fetches a page, so nothing you analyse leaves your browser. To check a live page, copy its visible content (or the section you care about) and paste it in. That keeps the tool fully private and instant.

No. All counting and phrase analysis runs in your browser, so you can safely check unpublished drafts and client content — nothing you paste is sent to a server.
