Keyword density refers to the percentage of times a keyword appears in a piece of content compared to the total number of words. For example, if the phrase “web design” appears 3 times in a 100-word text, the keyword density is 3%.
Formula:
Number of Keywords / Total Number of Words × 100 = Keyword Density
