Word Frequency Counter
A word frequency counter analyzes text to count how often each word appears. It calculates word count, percentage of total, and vocabulary richness (unique words / total words). Common uses: SEO keyword density analysis, writing style analysis, academic text analysis, and content optimization. Stop words (the, a, is, etc.) can be excluded to focus on meaningful content words.
Analyze any text to find word frequency, count, and percentage. Sort by frequency or alphabetically. Exclude stop words, set minimum word length, toggle case sensitivity. Export results as CSV. Visual distribution bars.

Frequently Asked Questions
- What is word frequency analysis?
- Word frequency analysis counts how many times each word appears in a text. It reveals the most common words, keyword density (percentage each word contributes), and vocabulary richness (unique words divided by total words). It is used in SEO, content writing, linguistics, and academic research.
- What are stop words and should I exclude them?
- Stop words are common function words like "the", "a", "is", "and", "of" that appear frequently but carry little meaning. Excluding them reveals the meaningful content words. For SEO keyword density analysis, exclude stop words. For linguistic analysis or readability research, keep them included.
- What is vocabulary richness?
- Vocabulary richness (also called lexical diversity) is the ratio of unique words to total words, expressed as a percentage. A 500-word text with 200 unique words has 40% vocabulary richness. Higher values indicate more diverse vocabulary. Academic writing typically shows 60-80% richness, while conversational text is 30-50%.
- How is keyword density calculated?
- Keyword density = (number of times a word appears / total word count) x 100. For example, if "calculator" appears 5 times in a 500-word text, its density is 1%. SEO best practice suggests keeping primary keyword density between 1-3% to avoid keyword stuffing penalties.
- What is a good word frequency for SEO?
- For SEO, your primary keyword should appear at 1-2% density. Secondary keywords at 0.5-1%. Anything above 3% may be flagged as keyword stuffing by search engines. Use this tool to check your content before publishing and ensure natural keyword distribution.
- Can I export word frequency data?
- Yes. Click "Copy as CSV" to copy the complete word frequency table (word, count, percentage) in CSV format. You can paste it directly into Excel, Google Sheets, or any spreadsheet application for further analysis, charting, or comparison.
