How to Use Word Frequency Counter
Basic Usage
Enter Your Text
Type or paste content into the text area. Analysis begins automatically as you type.
View the Results
The frequency table shows each word, its count, and keyword density percentage.
Adjust Filters
Use the controls to customize which words appear in results.
Export if Needed
Copy results or download as CSV for further analysis.
Using Filters
Stop Words Filter
Toggle Stop Words to hide common words like "the", "is", "and", "of". This helps you focus on meaningful keywords rather than grammatical words. Stop words are automatically loaded based on your language.
Case Sensitivity
By default, "Hello" and "hello" are counted as the same word. Enable Case Sensitive to count them separately.
This is useful when analyzing code, brand names, or content where capitalization matters.
Min Frequency & Min Length
Min Frequency: Set a minimum count to filter out words that appear only once or twice. For example, set to 3 to see only words appearing 3 or more times.
Min Length: Filter out short words by setting a minimum character length. Set to 4 to hide words like "a", "the", "is".

Real-Time Word Analysis
As you type or paste text, the analyzer processes your content immediately. There's no need to click a button—results update in real-time with a 300ms debounce to ensure smooth performance even with long texts.
Keyword Density Calculation
Each word shows its density percentage, calculated as: (word count ÷ total words) × 100. This metric is essential for SEO professionals who need to maintain optimal keyword density (typically 1-3% for primary keywords).

- European: English, German, Spanish, French, Italian, Portuguese, Dutch, Polish, Russian, and more
- Asian: Vietnamese, Japanese, Korean, Chinese, Thai, Indonesian, Hindi, Bengali
- Middle Eastern: Arabic, Persian, Hebrew
Visual Frequency Bars
Each word row includes a progress bar showing its relative frequency. The most frequent word has a full bar, with others scaled proportionally. This provides an instant visual comparison without reading the numbers.
Flexible Sorting Options
- By frequency - See most or least common words first
- Alphabetically - Find words quickly in A-Z or Z-A order
- By length - Identify your longest or shortest words
Click-to-Highlight
Clicking any word in the results table automatically scrolls to and highlights that word in your original text. This feature helps writers quickly locate and review word usage in context.

Responsive Design
The tool works on any device—desktop, tablet, or mobile. On smaller screens, the layout adjusts automatically to remain usable without horizontal scrolling.
Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a word appears compared to the total word count. For example, if "marketing" appears 5 times in a 200-word article, its density is 2.5%.
What are stop words?
Stop words are common words that appear frequently in text but carry little meaningful information—words like "the", "is", "and", "of", "to". Filtering them out helps you focus on the actual keywords and topics in your content.
Why should I filter stop words?
When analyzing content for SEO or writing quality, stop words can clutter your results. Without filtering, words like "the" and "and" often dominate the frequency list, making it harder to see which meaningful words you're using most.
Does this tool support my language?
Yes, the tool supports text in any language with Unicode characters. Stop word filtering is available for 30+ languages including English, Spanish, French, German, Portuguese, Italian, Dutch, Russian, Vietnamese, Chinese, Japanese, Korean, Thai, Indonesian, Arabic, Hindi, and more.
How is word count calculated?
Words are identified by finding sequences of letters and numbers. Punctuation marks, spaces, and special characters are used as word separators. For example, "don't" counts as two words: "don" and "t".
What's the difference between "Total Words" and "Unique Words"?
- Total Words - The complete word count including repetitions
- Unique Words - The number of distinct words (each word counted once regardless of how many times it appears)
Can I analyze long documents?
Yes, the tool handles large texts efficiently. For very long documents (50KB+), there may be a brief processing delay, but the debounce mechanism ensures the interface remains responsive.
Is my text stored or saved anywhere?
No. All processing happens in your browser using JavaScript. Your text never leaves your device and is not stored, logged, or transmitted to any server.
How do I use this for SEO?
Paste Your Content
Add your content into the analyzer
Enable Stop Words

Check Density
Verify your target keyword's density (aim for 1-3%)
Review Overuse

Why do some words appear combined?
The tool splits text based on non-letter/non-number characters. Hyphenated words like "e-mail" become "e" and "mail". If you need to keep them together, consider replacing hyphens with a different format before analysis.
Can I save my analysis?
Use the CSV export feature to download your results. This file can be saved and opened later in any spreadsheet application for record-keeping or comparison.
