What is Word Frequency?

- Vocabulary variety and writing style
- Term distribution in documents

What Good Frequency Looks Like
For SEO:
- Target keywords appear 1-3% of total words
- Related terms appear naturally throughout
- No single word dominates excessively
For Writing:
- Varied vocabulary (no word exceeds 5%)
- Minimal filler words like “very” or “really”
- Natural word distribution
Minimum Word Length Explained
The minimum word length filter helps you focus on meaningful words:
Length 1: Includes single letters (a, I) - usually too noisy
Length 2: Includes “is”, “it”, “at” - many filler words
Length 3: Default - balances common words with meaningful terms
Length 4+: Focuses on longer, more meaningful words
Recommended: Use length 3 for general analysis, length 4+ to exclude common short words.
Frequently Asked Questions
How does the word frequency analyzer work?
The analyzer converts your text to lowercase, removes punctuation and symbols, splits text into individual words, filters by minimum word length, counts each unique word, and ranks them by frequency. Results show both count and percentage of total words.
What does the percentage mean?
The percentage shows how much of your total text that word represents. For example, if “data” appears 10 times in a 100-word text, it’s 10% of your content. This helps identify if words are overused.
Can I exclude common words like “the” and “and”?
Yes! Set the minimum word length to 4 or higher to automatically exclude most common short words. Alternatively, you can manually review results and note which words to reduce in your writing.
Does it work with multiple languages?
Yes! The analyzer uses Unicode character detection and works with 100+ languages including English, Spanish, French, German, Chinese, Japanese, Arabic, Ukrainian, and more. It properly handles accented characters and non-Latin scripts.
Why is minimum word length set to 3 by default?
Length 3 provides a good balance between including meaningful words and excluding very common short words. You can adjust from 1-20 based on your needs. Use higher values (4-5) to focus only on substantial words.
How many results can I see?
You can display anywhere from 5 to 100 top words. The default is 20, which is usually sufficient for most content analysis. Increase it to 50-100 for longer documents or comprehensive analysis.
What’s a good keyword frequency for SEO?
For SEO, target keywords should appear 1-3% of total words. If a keyword appears more than 5%, it may be overused (keyword stuffing). Use related terms and synonyms to maintain natural language while optimizing for search.
Can I analyze code or programming files?
Yes, but results may be less useful since code has different patterns than natural language. The analyzer will count function names, variable names, and keywords. Consider filtering out single-character words and setting minimum length to 4+.
Is my text data private?
Absolutely. All analysis happens entirely in your browser using JavaScript. Your text never leaves your device, and we don’t log, track, or collect any data. The tool works completely offline after initial load.
How is this different from a keyword density checker?
Word frequency shows ALL words ranked by usage, while keyword density focuses on specific target keywords. Use word frequency for general content analysis and discovering patterns. Use keyword density when optimizing for specific SEO terms.
