What is Keyword Density?
Keyword density is the number of times a keyword appears in a piece of content compared to the other words in the content. It is calculated by dividing the number of times the keyword appears by the total word count and multiplying by 100.
Search engines use keyword density to determine the relationship between a keyword and the content in which it appears. The more the keyword appears, the more relevant it is to the content.
The idea behind using keyword density to determine the relationship between a keyword and the content is based on the premise that keywords related to the content will appear more frequently than those unrelated to the content.
Keyword density used to be an important factor in SEO, but search engines now focus more on the quality and relevance of the content. So, it is recommended to create content that sounds natural and provides value to the reader instead of excessively focusing on achieving a specific keyword density.
