Keyword Density  

Keyword density refers to the number of times a keyword appears on a given webpage or within a piece of content as a ratio or percentage of the overall word count. This is also sometimes referred to as keyword frequency, or the frequency with which a specific keyword appears on a webpage.

Keyword density can also be calculated as a specific figure, should you need to. To determine the keyword density of a webpage, simply divide the number of times a given keyword is mentioned by the total number of words on the page – the resulting figure is the keyword density of that page.
