This keyword density checker counts how frequently words and phrases appear in a block of text or on a given URL and calculates their relative share of total content. It is intended to help you understand whether certain terms are underused, naturally integrated, or possibly overused in ways that might look unnatural to users and search engines. By pasting content or analyzing a page, you receive a breakdown of top keywords with percentages. This can guide small adjustments in wording and structure so that important topics are clearly emphasized without falling into keyword stuffing. Writers, bloggers, and SEOs can all use this tool to fine tune content before publishing.
