Keyword Density
Keyword Density is a critical factor in search engine optimization. Our tool analyzes the text content of any web page or provided text to identify the most frequent words and phrases. It calculates the percentage of each keyword relative to the total word count, helping you avoid keyword stuffing while ensuring your content remains relevant to your target search terms. The method is deliberately transparent: text is lowercased, punctuation is stripped, and tokens shorter than three letters are dropped before counting. A stop-word list then removes articles and connectives from the frequency table while they remain in the denominator, so the percentages reflect real content words. URL mode fetches the page through a proxy and strips scripts, styles, navigation, and footers first, and the twenty highest-count words are ranked with anything above 3% highlighted as a stuffing risk.

Questions People Ask
Honest answers about how this works.
What even is a good keyword density?
Most SEO guidance puts your primary keyword between 1% and 2% of total words, with secondary terms lower still. Below that, the topic may not read as relevant; above 3%, the Keyword Density tool flags the row as a stuffing risk. Treat the percentage as one signal alongside natural phrasing and coverage of related terms.
Does it exclude common words?
Short answer: Yes. The tool drops stop words such as 'the', 'and', and 'is' from the ranked frequency table so you see content words first, and it ignores tokens shorter than three letters. Stop words still count in the denominator, which keeps the density percentages aligned with the true total word count.
How exactly is density calculated?
The Keyword Density tool lowercases your text, removes punctuation, and drops tokens under three letters. It counts the remaining words, excludes stop words from the ranked table but keeps them in the denominator, then divides each word's count by the total word count times 100. The top 20 results are shown.
