With this plugin you can optimize your WordPress blog for search engines. 
It can automatically generate meta informations (like keywords and description for example) needed for the search engine optimization (SEO) of your blog.
The 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 keywords suggestion. 
Based on this list a META description can be created and automatically set. 
So the plugin can be used to do the on-page part of your SEO strategy.

Please notify: The SEO-relevant meta-information (meta keywords, meta description and the robots meta-tag) will be generated – and served – only for pages and posts which are saved after plugin installation. 
You have to open and save an older post or page if you want to generate the meta data for the particular content. 
For now there is no way to do this automatically.
The administrator can allow ordinary authors to change META informations or not. 
Even if changing is disallowed an author can see the keyword density and can be guided from the statistics while he is writing the content. 
He can do the on-page search engine optimization incidentally by knowing which keyword density should be reached. 
This makes SEO easier for authors.
