Calculation of Keyword Density for Keyword Phrase - To calculate keyword density for a keyword phrase, the formula is (Nkr*Nwp/Tkn)*100. - Nwp represents the number of words in the phrase. - For example, a four-hundred word page with the phrase 'search engine optimization' used four times would have a keyword phrase density of 3%. - The calculation considers the frequency of the phrase within the text. - Keyword phrases consisting of multiple terms should be treated as a single appearance.
