Keyword Density

Keyword density is a metric that quantifies the number of times a keyword appears on a web page as a percentage of the total number of words on that page. Search engines look at the keyword density for a particular term on a page to determine the relevancy of that page for that keyword. That relevancy score is one of the factors in the search engines' algorithm to determine the rank of the page for that specific keyword.
