Keyword Density: An old measure of search engine relevancy based on how prominent keywords appeared within the content of a page. Keyword density is no longer a valid measure of relevancy over a broad open search index though. When people use keyword stuffed copy it tends to read mechanically (and thus does not convert well and is not link worthy), plus some pages that are crafted with just the core keyword in mind often lack semantically related words and modifiers from the related vocabulary (and that causes the pages to rank poorly as well).
