HOW IT WORKS
How to use the Keyword Density & N-Gram Analyzer
Any text, such as a page’s body copy.
Paste the text you want to analyse.
Choose single words or two- or three-word phrases.
Look at the top phrases and edit any that repeat unnaturally.
WHAT IT CHECKS
What it looks at, and how to read it.
The top 100 words or phrases with counts and density, downloadable as CSV.
What it checks
- Word and phrase frequency in any language
- Density as a share of all phrases of the same length
- Optional removal of common words
How to read the results
- High counts of the main topic are normal; high counts of a filler phrase usually are not.
- Compare phrases with your target searches to see whether the text uses the same words people do.
GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- Aiming for a specific density percentage.
- Repeating a phrase to raise its count, which makes text read worse.
A worked example
A category page repeats "best price" 14 times in 600 words. Replacing half of them with specific details reads better and says more.
Limitations
- Density is descriptive. Google has no target keyword density, and a higher number never means a better page.

Straight answers about what it does and where its limits are.
What is a good keyword density?
There isn’t one. Write naturally and make sure the topic is covered; use this tool to catch repetition, not to hit a number.
