Keyword density is the term used to express how often a targeted keyword is used on a web page. Keyword density is determined by dividing the total word count of the page by the number of times the keyword appears. This concept is very important for webmasters because Google expects webmasters to drive traffic organically through the use of keywords and the content containing these keywords. It should not come as a surprise when Google detects and penalizes pages in which keywords are used to the extent of spamming, thinking that it would be beneficial SEO-wise.
