One thing pageoneresults mentioned that made me remember that Slurp will also try to fetch the default document if the URL is in subdirectory:

http://www.example.com/directory/sub-directory/page1

it will try

http://www.example.com/directory/sub-directory/

and

http://www.example.com/directory/

and if

http://www.example.com/directory/ is the same content as http://www.example.com/directory is there a duplicate content issue on Yahoo SERP?

So, that SEO firm was probably doing that for a reason.

Something to think about...
