Overview
What this tool does
Paste any text and see how often each word appears, ranked from most to least frequent, with keyword density percentages and a visual bar chart. Filter out common words, ignore case, and set a minimum word length to focus on what matters. Everything runs in your browser.
The basics
What is keyword density?
Keyword density is how often a specific word appears as a percentage of the total words counted. If "coffee" appears 8 times in a 400-word article, its density is about 2%. Writers and SEOs track density to confirm a target keyword appears naturally — present enough to signal the topic, but not so much that it reads as spam.
SEO guidance
What's a healthy density?
There's no magic number, and modern search engines focus on meaning and context far more than raw counts. As a rough guide:
- 1-2% for a primary keyword usually feels natural
- Supporting and related terms matter as much as the exact keyword
- Above 3-4% starts to look like keyword stuffing, which can hurt rankings
- Write for readers first — if it reads naturally, the density is usually fine
Density is a sanity check, not a target
Getting useful results
The filters explained
Ignore common words
Words like "the", "and", "of", and "a" dominate every English text but carry no topical meaning. Filtering them out reveals your actual content keywords. On by default for that reason.
Ignore case
Merges "Coffee", "coffee", and "COFFEE" into one count. Turn it off when capitalization matters — for example, to count a proper noun separately from a common word.
Minimum word length
Hides very short words (set it to 3 or 4 to skip "a", "to", "of"). Useful for focusing on substantial words even without the stopword filter.

Common questions
How do I find the most common words in a text?
Paste the text and the tool ranks every word by frequency. Turn on "ignore common words" to skip filler and surface the meaningful keywords at the top.
What keyword density should I aim for?
Around 1-2% for your primary keyword feels natural. There's no official target, and writing for readers beats chasing a number. Use the tool to avoid both under-using and over-stuffing a keyword.
Does repeating a keyword help SEO?
Up to a point — your keyword should appear enough to signal the topic. But excessive repetition (keyword stuffing) is penalized. Related terms and natural phrasing matter more than raw repetition.
Can I analyze very long text?
Yes. The tool handles long articles and shows the top results ranked by frequency. For very large texts it displays the top 200 unique words to keep the view readable.
Does it count phrases, not just single words?
This tool counts individual words. Single-word frequency is the most common analysis and the basis of keyword density. For multi-word phrase analysis you'd need a dedicated n-gram tool.
