Readability Analyzer

This module is designed to help copywriters and editors develop more consistently readable content across a Drupal site. It performs five popular automated readability tests that provide a grade level equivalency of the difficulty of a page's readability:

• Flesch Kincaid
• Gunning Fog Score
• Coleman Liau Index
• SMOG Index
• Automated Readability Index

It enables you to set a target grade range for your site's content. The analysis will indicate if the subject content falls within the targeted range or provide a warning otherwise.

Leveraging the Content Analysis API it provides multiple interfaces to quickly analyze any page on your Drupal site (or any page on any website for that mater):

• Node edit– enables you to optimize content while adding or editing nodes without having to leave the node edit form or saving the node. (node edit demo)
• Block – Provides a block to search optimize any page on your site including themed nodes, views, panels and coded pages. (block demo)
• Admin form – provides additional analysis input options including a text area for optimization of free form content, a URL input enabling analysis of any accessible page on the web, and a node id input for analysis of saved nodes. (admin form demo)

The analysis is based on the php-text-statistics project. (You can access the code in svn here: http://code.google.com/p/php-text-statistics/source/browse/trunk/TextSta...) Just download the object class TextStatistics.php and supporting files. Then place the files in a directory named "php-text-statistics". It is free, open source project.
