Clean Sweep is a plugin that assists administrators in finding and fixing Broken inbound links to their website. It was build to support two use cases:
*to help users get a clean start with their blog by allowing them to completely restructure their permalink URL structure and have a system that can automatically ADAPT by redirecting stale and inbound links to the proper destination
*to help users in the process of migrating to Movable Type who are forced to modify their web site's URL and permalink structure
Both of these use cases have to do with preserving a site's page rank in light of a major redesign.
Features and Benefits
* Manage redirects in your blog using an easy to use user interface.
* Help maintain good SEO and page rank by keeping links fresh.
* No need to hack Apache configuration files until you are sure your redirects are correct.
