Definition of Keyword Density

Keyword Density refers to the number of times or percentage that a specific keyword or keyword phrase appears in a document or on a webpage compared to the total number of words that are included in the document or page. For example, a webpage contains 300 words. A specific keyword is repeated or used within the page 18 times. To calculate the keyword density, you take the number of times the keyword is present and divide it by the total number of words. Therefore, 18 is divided by 300, which returns an answer of .06. This number is then multiplied by 100 to calculate the percentage. The resultant answer is 6%.

Keyword density is an important consideration in search engine optimisation. The Keyword or keyword phrase density of a page is used to determine the webpage’s relevance to a specified keyword or keyword phrase. Only white hat SEO practices should be utilised for keyword inclusion.
