Our Keyword Density Checker will help you analyze your site for on-page SEO issues. Using our tool should be fairly self-explanatory, but the basic idea is to enter the address of the page you want to analyze, then click 'Check Keyword Density'. You can optionally enter multiple keywords you want highlighted, in comma separated format, in the keywords input field. All occurences of the keywords/phrases you enter will be highlighted for you even if it is a subset of a keyword or phrase on the page.
