Content Optimizer
The Content Optimizer module for Drupal will help Drupal Developers improve the on-page SEO of their Drupal nodes. The module helps improve the search engine rankings of a Drupal website by analysis of page content with a guide to help webmasters follow best practices. The Content Optimizer performs an analysis using the Content Analysis API and Chaos Tools to provide an AJAX report of nodes, blocks, and admins forms. The analysis provides statistics for character count, word count, keyword count, keyword density, and keyword prominence. The module also works with the Page Title and Meta Tags modules.
