The percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page is known as keyword density. SEO experts consider the optimum keyword density to be 1 to 3 percent. The formula to calculate your keyword density on a web page for SEO purposes is (Number of times repeated a specific keyword / the total words in the analyzed text) * 100. This will result in a keyword density value.

Example: Let the phrase is used four times and there are four hundred words on the page, the keyword phrase density is (4*3/400)*100 or 3 percent.

Best Keyword density should be between 3-5%. Hope that helps!

Keyword density varies with the type of content but if you keep 1-2% it produces good result among various search engines and also makes website lovable.

It should be 2-4%.

I am wanting to know how to calculate keyword density (what is the formula) and what is the optimum range of keyword density for SEO purposes?

Obviously, I am wanting to rank well however I do not want to be seen as 'keyword spamming' or 'keyword stuffing'.
