Keywords are the backbone and pillars of any SEO strategy. In keyword terms, there are many aspects and one important is Keyword density. Keyword density means how many targeted keywords and search terms available on the web pages.
Keyword density varies between one search engine to another search engine, or also they require different amounts of keyword density on a web page in order to index the website. Sometimes, a web page may not have good or effective content keyword density; however, they rank higher in Google SERP, because of their brand value or brand authority. Search engines like Google recommend a keyword density is 1 to 2% while Yahoo allows a website that has 3%.

After understanding the Keyword density, let’s take a look at how to calculate

For calculating the keyword density using a simple formula, take how many times your keyword appears in your webpage and divides that keyword appears to the total number of words present on that web page then multiply that result by 100. After all that calculations, you get the actual amount of keyword density.

Simple way: number of repeats the keyword / total number of words on the web page * 100 = Keyword Density

Write content for people, not for search engines because high keyword density may be harmful or search engines could penalize your website. When you write the content from the user's point of view, this is very beneficial to rise or improves rankings in Google SERP.
