Keyword stuffing and Keyword spamming are essentially the same. This could be classed as a black-hat SEO practice, and as the name indicates, involves spamming keywords in a page or in a blog entry.

While Keyword density is the percentage of times a keyword or phrase appears in a web page compared to the total number of words on the page.
