New and Free at the Marketplace: Link Checker and Validation Module
Check your web pages for validity and accessibility with a single click!
The Link Checker and Validation Module provides a simple way to check a chosen page for broken links and validate its compatibility with standards for accessibility, (X)HTML and mobile websites. It uses on-line services, so the page that you're checking must be published and publicly accessible. The tool integrates directly into the Properties menu of a document, so any user can use it to validate the content.
The module was developed by Zbysek Nemec (Kentico) and it was tested to work with Kentico CMS 5.5. Advanced versions of the Link Checker and Validation Module will be a standard part of Kentico installation from the version 6.0, which is planned to be released during Q2/2011.
