What is the Right Keyword Density on a Page?

Keyword density is one of the key factors content creators think of most. Keywords are basically the terms people type into the search bar to get search results and web content writers often think that the more number of times they can mention keywords in a copy the higher their web pages will rank. This may have been true in the earlier days of Google search where a lot of websites used keyword stuffing to successfully raise their ranks. However, current search engine algorithms and the Penguin and Panda updates have ensured that content and not the keyword density matters most for the ranking of webpages.
