How it Works
A lot of us lose out on valuable search engine traffic due to incorrectly configuring our redirects.
It is very import that when a search engine comes to crawl your website it is able to follow any redirects you have set up.
Suppose you have a website http://www.foo.com and you create a redirect such that whenever any visitor types in the URL
http://www.foo.com he is automatically redirected to http://www.foo.com/widgets/,
If the Search Engine is not able to follow the redirect it would think that http://www.foo.com has NO contents, http://www.foo.com would end up ranking very badly in search engines.
This tools help you determine if the redirect you have created is Search Engine Friendly.
