This tool counts single-word frequency across your pasted content and ranks the most common ones, ignoring common filler words like "the" and "and".

Frequently asked questions
Is there an ideal keyword density percentage?

Why are common words like 'the' excluded?
They're filtered out because they appear in almost all English text and don't indicate topical focus.
