Free Word Frequency & Keyword Density Counter Online

Q: What counts as a stop word?

Stop words are very common words like the, is, and, and of that carry little unique meaning on their own. Excluding them helps highlight your actual topic keywords.

Use this free word frequency and keyword density counter to see exactly which words and phrases dominate your text, how many times each appears, and what percentage of your content they make up — useful for checking SEO keyword density, spotting overused words, and tightening up your writing.

What is keyword density and why it matters

Keyword density is the percentage of times a specific word or phrase appears relative to the total word count of a piece of text. This matters for two main reasons: for SEO, search engines look at how naturally your target keywords are used — too low and your content may not be relevant enough, too high and it can look like keyword stuffing, which hurts rankings. For general writing, seeing your most repeated words also helps you catch overused phrases and improve variety.

How this tool works

Paste your text and click "Analyze Text." The tool splits your text into individual words, optionally filters out common stop words like "the," "and," and "is" so the results focus on meaningful terms, then counts how often each word appears. It calculates each word's density as a percentage of your total word count and displays the results as a ranked table with a visual bar for quick comparison.

Tips

For SEO content, most guidance suggests keeping a target keyword's density naturally low (often well under 3%) rather than forcing repetition.
Leave "Exclude common words" checked to focus on meaningful keywords rather than filler words.
Check density for keyword phrases too by scanning the text manually — this tool analyzes single words.
Use the results to spot accidental overuse of a word you didn't realize you were repeating.

No. All analysis happens locally in your browser; your text is never sent to a server.

What counts as a "stop word"?
Stop words are very common words like "the," "is," "and," and "of" that carry little unique meaning on their own. Excluding them helps highlight your actual topic keywords.

Does this tool analyze keyword phrases, not just single words?
This version analyzes individual words only. For multi-word phrase density, you'd need to search your text manually for that phrase.

What's a good keyword density for SEO?
There's no single official number, but most SEO guidance suggests keeping keyword usage natural rather than targeting a specific percentage — over-optimizing can hurt more than help.
