How Keyword Density Analyzer works

This tool tokenizes your text, removes common English stop words (the, and, is, etc.), and counts the frequency of remaining words or n-grams. Keyword density is calculated as (keyword count / total word count × 100). The results are sorted by frequency and displayed with visual bar charts. N-gram analysis lets you see popular 2-word and 3-word phrases. Everything runs in your browser — your content is never sent to any server.

Frequently asked questions

What is keyword density and what is a safe range?

Keyword density is the percentage of times a keyword appears compared to total word count. For most SEO content, about 1–2% per keyword is a common guideline. Avoid keyword stuffing.

Does it support 2-word and 3-word phrases?

Yes. Switch between single words, 2-word phrases, and 3-word phrases to analyze n-grams.

Are stop words removed?

Yes. Common words like 'the', 'and', and 'is' are filtered so you can focus on meaningful keywords.

Is the analysis case-sensitive or punctuation-aware?

No. The tool lowercases text and removes punctuation before counting, so results are case-insensitive and consistent.

Is my content uploaded to a server?

No. All analysis runs locally in your browser and your text never leaves your device.

Is there a length limit?

There is no hard limit, but very long documents can be slower. For best performance, analyze sections one at a time.
