It adds a fieldset to the node edit forms with a targeted keyword phrase field and an “Analyze Content” button. When clicked the, the module sends your body, title and other content to the sever via AJAX and returns recommendations on how to better optimize each of your content areas. Statistics are also returned for each area, including character count, word count, keyword count, keyword density and keyword prominence. The statistics and recommendations are embedded via JavaScript underneath the node input fields for easy editing.
The Content Optimizer also works with the Page Titles and Meta Tags (AKA Nodewords) Drupal modules, highly recommended for Drupal SEO, for advanced page optimization.
