Did you have an idea that the number of times a keyword appears on your web page in relation to the overall number of words on that page might affect its ranking?
Yes, and it's known as "Keyword Density."
If you use a keyword or phrase too often, search engines will certainly penalize your site. If you do it a little less than required, search engines may not be able to perceive adequate signals to rank the website for that specific term. Simply said, for the greatest search results, you should get your keyword density just perfect. It's impossible to have less or more!
But where do you begin when estimating the number of times a term appears on a web page or blog post? Is it even possible for you to do it correctly?
