Frequently asked questions
How is word frequency calculated?
The text is split into individual words (case-insensitive, punctuation ignored), then each unique word is counted and sorted by how often it appears.
What is word frequency analysis used for?
It's used for SEO keyword density checks, writing style analysis, and finding overused words or phrases in a document.
Does this count 'the' and 'The' as the same word?
Yes - word frequency counting is case-insensitive by default here, so capitalization at the start of a sentence doesn't split a word's count across two separate entries.
How can word frequency analysis help with SEO or writing?
Word frequency analysis reveals unintentional repetition, helps confirm target keywords appear at a natural density rather than being stuffed, and can surface overused filler words that weaken writing - useful for both editing prose and checking on-page SEO content before publishing.
Does punctuation attached to a word, like 'dog,' or 'dog.', get counted separately from 'dog'?
No - punctuation is stripped before counting, so "dog," "dog." and "dog" are all tallied as the same word, avoiding artificially split counts caused by trailing commas or periods.
In the example text, how many times does 'the' appear?
Twice - "the quick brown fox jumps over the lazy dog the fox runs fast" actually has 'the' three times (before 'quick,' before 'lazy,' and before second 'fox'), each counted the same regardless of position in the sentence.
Is this the same as a 'keyword density checker'?
They're closely related - a keyword density checker usually expresses a target word's frequency as a percentage of total words, while this tool ranks all words by raw frequency count. You can manually compute density from the counts and total word count this tool provides.
