Word Frequency Counter
The Word Frequency Counter analyzes any text and shows how often each word appears, sorted from most to least frequent. Paste an article, essay, or document to instantly see a sorted table of every word and its count, along with its percentage of the total text.
The tool includes a stop-word filter for English, Portuguese, and Spanish that removes common function words (like 'the', 'and', 'of') so you can focus on meaningful content words. Ideal for writers, researchers, SEO professionals, and students who need to analyze vocabulary diversity, keyword density, or writing patterns.
How it works
Each word is extracted by splitting text on whitespace, converted to lowercase, and stripped of punctuation. Frequency is calculated by counting occurrences and dividing by the total word count to get the percentage.
Use cases
- Analyzing keyword density for SEO content optimization
- Studying vocabulary diversity in essays and academic papers
- Identifying repetitive words to improve writing quality
- Comparing word usage patterns across different texts or authors
- Extracting key themes from surveys, reviews, or open-ended responses
Frequently asked questions
How do I count how many times each word appears in a text?
Paste your text into the counter and it splits the content on whitespace, lowercases each word, and strips punctuation before tallying occurrences. The result is a table of every distinct word sorted from most to least frequent, with its count and percentage of the total. No installation or upload is required — everything runs in the browser.
What are stop words and why filter them out?
Stop words are common function words like 'the', 'and', and 'of' that carry little topical meaning but usually dominate any frequency list. Filtering them lets the meaningful content words rise to the top so you can see the real themes of a text. This tool includes stop-word lists for English, Portuguese, and Spanish.
How is keyword density calculated?
Keyword density is the number of times a word appears divided by the total word count, expressed as a percentage. For example, a keyword used 12 times in a 600-word article has a density of 2%. The counter shows this percentage for every word automatically, which is useful for spotting over-optimization in SEO content.
Does capitalization affect the word counts?
No. Every word is converted to lowercase before counting, so 'Word', 'word', and 'WORD' are tallied as the same entry. Punctuation attached to words is also stripped, so 'word,' and 'word' count together. This normalization gives an accurate picture of true word usage.
How can writers use a word frequency counter to improve their text?
Sorting words by frequency exposes unintentional repetition — if a non-essential word appears far more often than its peers, it is a candidate for synonyms or rephrasing. Comparing frequency tables across drafts or authors also reveals differences in vocabulary diversity. Researchers use the same technique to extract dominant themes from surveys and open-ended responses.
