Usually, the contents should not be over stuffed with keywords but a neat three keywords in approximately 500 words article will work as the best verdict for your contents. Pick three keywords that have one major keyword and two sub-keywords. The title of your content must also content the major keyword without fail and the wisest decision is to choose a good title and a subtitle and adding them to your first and second paragraph within an appropriate sentence.
