Multi Keyword Statistics Instruction Page .The multi-keyword-statistics-Plugin checks the content of a post or a page for keyword-density (single words and optionally 2- and 3-word phrases; for each the 1-10 most commonly used can be displayed). It can update its informations automatically while the author is writing his content in a variable interval (every 1-10 seconds) or manually by clicking on a button. The script comes with english and german stopwords, which optionally can be filtered out before calculating the keyword-densities. Moreover the commonest keywords are extracted in a list as a meta-keyword suggestion. Based on this list a description can be created and automatically set.
