Keyword stuffing is considered to be an unethical search engine optimization (SEO) technique.
Google’s own Matt Cutts warned webmasters about SEO keyword stuffing and over optimization - "We are trying to level the playing field a bit. All those people doing, for lack of a better word, over optimization or overly SEO – versus those making great content and a great site. We are trying to make GoogleBot smarter, make our relevance better, and we are also looking for those who abuse it, like too many keywords on a page, or exchange way too many links or go well beyond what you normally expect. We have several engineers on my team working on this right now."
