Word Frequency Counter
Paste any text and instantly see a ranked table of how often each word appears — with counts and percentages. Perfect for SEO keyword density checks, spotting overused words and analysing content patterns. Everything runs privately in your browser.
How to Use the Word Frequency Counter
Paste your text in the input box and click Analyse. The table shows every word ranked by how often it appears, along with its percentage of the total word count. Options:
- Case-sensitive — treats "Apple" and "apple" as different words.
- Ignore stop words — filters out common words like "the", "a", "and", "is" that don't carry meaning.
- Min length — hides words shorter than the specified number of characters, useful for filtering out short filler words.
Word Frequency and SEO Keyword Density
Search engines look at how often your target keyword appears relative to all words on the page. A keyword density of 1–2% is generally considered healthy. Too high (above 4–5%) can look like keyword stuffing. Use this tool together with the Word Counter to check total length and density at the same time.
Academic and Research Uses
Linguists and researchers use word frequency data to study language patterns, detect authorship, and compare documents. Frequency analysis is also the foundation of many natural language processing (NLP) algorithms, including spam filters and sentiment analysis engines.
Frequently Asked Questions
What is word frequency analysis used for?
It is used in SEO for keyword density checks, in academic research to study language patterns, in content editing to spot overused words, and in NLP tasks.
Does the counter ignore common words?
Enable stop-word filtering to exclude common function words like the, a, an, is, and. This highlights meaningful keywords rather than grammatical filler.
Is the word count case-sensitive?
By default it is case-insensitive, so "Apple" and "apple" are counted together. Enable the case-sensitive toggle to distinguish them.
How is the frequency percentage calculated?
Each word's percentage is its count divided by the total number of words, multiplied by 100 — the share of the text that word occupies.
