The number of times a keyword is used on a web page out of the total number of words on the page. Let’s say your keyword is “handmade quilt.” The formula would be: number of “handmade quilt” / total number of words, x 100. If your page includes “handmade quilt” 10 times, and your page has 300 total words, your keyword density for “handmade quilt” is 3%. The higher your keyword density, the higher search engines will rank your page for relevance. Just avoid “keyword stuffing.”
