How it works
The Word Density Analyzer calculates the frequency of every word in a block of text, ranked from most frequent to least. It shows word count, percentage of total words, and a visual frequency bar — giving you an instant view of your text's keyword composition.
Word density is a foundational concept in SEO and content analysis. Search engines use word frequency as one signal when determining a page's topic relevance. A page about "coffee brewing methods" should use those words proportionally throughout. Over-stuffing keywords is penalized; under-using them misses ranking opportunities.
How to use it: paste your content. The tool shows the top 50 words by frequency with their count and percentage. Common stop words (the, a, is, to, and) are filtered out by default so the meaningful keywords dominate the list. Toggle "Include stop words" to see the full frequency table.
SEO application: compare your word density against a target keyword. If you're writing about "French press coffee" and "French press" appears only once in 800 words, you may be under-representing your topic. Conversely, if it appears 20 times, that's keyword stuffing — rewrite to use synonyms and related phrases.
Content editing: word density analysis reveals when you've unconsciously repeated words that make writing feel repetitive. Seeing that "important" appears 11 times in a 500-word piece prompts you to use synonyms, improving readability alongside content quality.
Frequently Asked Questions
- Stop words are common words (the, a, is, to, of, and, in) that carry little semantic meaning and would dominate any frequency analysis. The tool filters them by default, showing only meaningful content words.
- Density percentage = (number of occurrences / total word count) × 100. A word appearing 10 times in a 500-word text has a 2% density.
- There is no universally agreed number, and Google does not endorse keyword density as a ranking factor. Most SEO practitioners suggest 1–3% for a primary keyword. Avoid repeating the same exact phrase — use synonyms and related terms for natural coverage.
- The standard view counts individual words. Enable 'Bigrams' to also see the most common two-word phrases, or 'Trigrams' for three-word phrases — useful for detecting repeated sentence structures or over-used keyphrases.
