Frequently asked questions
How is keyword density calculated?
Density is the number of times a phrase occurs divided by the total word count, shown as a percentage. The tool also lists raw occurrence counts.
What does stopword filtering do?
It hides extremely common words like "the", "and", and "of" (and phrases containing them) so the results highlight meaningful terms instead of filler.
