Keyword density checker

There is no target percentage

Google does not have a keyword density it prefers, and its people have said so for well over a decade. Its spam policies name the opposite problem: repeating words so often that the text reads unnaturally. So do not use this to push a phrase up to some number.

What it is good for

Catching repetition you have stopped seeing. Paste a draft and look at the two and three-word phrases. If one phrase turns up twelve times in 800 words, a reader notices even if you did not, and that is the line to rewrite.

Checking the phrase appears at all. A draft about standing desks that never says "standing desk" in a heading or the first paragraph has drifted.

Spotting machine habits. Drafts written by AI tend to lean on a few favourite phrases. When we read 39 posts on AI SEO vendors' blogs, the same stock phrases came up post after post on the same site. The three-word list finds them quickly.

How density is calculated

Occurrences, times the number of words in the phrase, divided by total words. A two-word phrase used five times in a 500-word draft is 2%. Common words such as "the" and "of" are left out of the single-word list, and a phrase may contain them ("cost of living") but not start or end with one.
