Keywords density and consistency are notable factors for optimal page SEO. Preferred keywords should have higher keywords density indicating their importance. Optimally, preferred keywords should also be consistently utilized in multiple essential areas of the page such as title, description meta tag, h1 through h6 headings, alt image attributes, back-links and internal links anchor text. Keyword density of above 5% is a good indication that the word or phrase appears too many time in the content.
