Understanding Word Frequency Analysis
What is a Word Frequency Counter?
A word frequency counter is a tool that counts how many times each word appears in a text and calculates its percentage of the total word count (keyword density). Our word frequency counter tokenizes your text by splitting on non-alphabetic characters, counts each word occurrence, and presents the results in a sortable table with frequency counts and density percentages. You can filter out common stop words to focus on meaningful keywords, set a minimum word length to exclude short words, and sort results by frequency, density, or alphabetically. All analysis runs locally in your browser - your text never leaves your device.
How Our Word Frequency Counter Works
- 1. Paste Your Text: Paste any text into the input panel - articles, blog posts, essays, product descriptions, or any content you want to analyze. The word frequency counter updates results in real time as you type.
- 2. Configure Filters and Sorting: Choose a minimum word length, enable stop word filtering to exclude common words like "the" and "and", and select a sort order (by frequency, density, or alphabetically). Set the result limit to show the top 20, 50, 100, or all words.
- 3. Analyze and Export Results: Click Analyze Text to confirm the analysis. Use the filter box to search within results. Copy the full results table as TSV (tab-separated values) for use in Excel, Google Sheets, or any spreadsheet application.
What the Word Frequency Counter Shows
- Word Frequency Count: The number of times each word appears in the text. Words are tokenized by splitting on non-alphabetic characters, so punctuation and numbers are excluded from word counts.
- Keyword Density Percentage: The frequency of each word as a percentage of the total word count. For example, if "content" appears 5 times in a 100-word text, its keyword density is 5%. SEO best practice recommends keeping target keyword density between 1-3%.
- Stop Word Filtering: Stop words are common function words (the, and, is, in, etc.) that carry little semantic meaning. Filtering them out reveals the meaningful keywords in your text. Our word frequency counter includes a comprehensive English stop word list.
- Lexical Diversity: Lexical diversity is the ratio of unique words to total words, expressed as a percentage. Higher lexical diversity indicates richer vocabulary. A score above 60% is generally considered good for content writing.

Frequently Asked Questions About Word Frequency Counter
A word frequency counter counts how many times each word appears in a text and calculates its percentage of the total word count (keyword density). Our word frequency counter presents results in a sortable table with frequency counts and density percentages, with stop word filtering and minimum word length options.
Keyword density is the percentage of times a target keyword appears relative to the total word count. SEO best practice recommends keeping target keyword density between 1-3%. Too low and the page may not rank for the keyword; too high (keyword stuffing) can result in a Google penalty.
Stop words are common function words like "the", "and", "is", "in", and "of" that carry little semantic meaning. Enable stop word filtering to exclude them and focus on meaningful keywords. For SEO analysis, filtering stop words gives a clearer picture of your content's keyword focus.
Keyword density = (word count ÷ total word count) × 100. For example, if "content" appears 5 times in a 200-word text, its keyword density is (5 ÷ 200) × 100 = 2.5%. Our word frequency counter calculates this automatically for every word in your text.

Lexical diversity is the ratio of unique words to total words, expressed as a percentage. A score of 60% means 60% of the words in your text are unique. Higher lexical diversity indicates richer vocabulary and more varied writing. Our word frequency counter displays lexical diversity in the summary panel.
