What is Word Frequency Analysis?
Word frequency analysis counts how many times each word appears in a piece of text. It's used by SEO professionals to identify keyword density, by writers to avoid repetition, by data scientists for natural language processing (NLP), and by teachers to assess vocabulary in student essays.
Options Explained
Ignore case: Treats "The" and "the" as the same word.
Filter common words: Excludes stop words like "the", "is", "of", "and" — so you see meaningful keywords instead.
Min length: Ignores very short words (e.g. single letters like "a" or "I").
Show top N: Limits the results to the N most frequent words.

Frequently Asked Questions
What are stop words?
Stop words are common English words like "the", "is", "at", "of", "and" that appear very frequently in text but carry little meaning on their own. Filtering them helps reveal the words that actually define the topic of your text.
How is word frequency useful for SEO?
SEO experts use word frequency to check keyword density — the ratio of a target keyword to the total word count. Overusing a keyword (keyword stuffing) can hurt rankings. This tool helps you find the right balance.
