What is Keyword Density? Keyword density is how many times your keyword is placed in your article. Most use a percentage to determine how many times they will put a keyword in an article. For instance, if you have a 500 word article and want to achieve a keyword density of 5%, then you will need to have the keyword in your article exactly 25 times. You can find hundreds of resources and guides recommending one keyword density over another and the reasons behind the logic, however, in the end you will have to determine which density is more profitable for your articles. Each webmaster as their own density that they like to achieve based on past results. As long as you don't over optimize and you are making sufficient profit from your rankings, then you can choose whatever keyword density you like. The Right Density No matter what exact density you choose, it is important to place keywords so that there are more at the beginning and end to produce an hour glass effect. Having the right keyword density in your article makes it more likely that you will make money off of that article because it will rise in the search engine results and be seen by more people.
