here is a way to see the G analytics Dashboard of your competitors.
filetype:pdf "Dashboard"+Bounce Rate inurl:co.uk (this string will bring UK sites with the analytics Dashboard in PDF format. it doesn't end there. there is more you can do to the string. some of the results are 2 to 3 months old witch is not bad.
and "Usage Statistics for"+"2009" inurl:webstat . this one, is good to look at the User Agents ( who is crawling that site?). again, you can "tweak this string" to see what you need to see. for example think of a User Agent that visits your competitors server and add it to the string. it works.
What levo said. This happens when someone exports a PDF and then puts the PDF up in a public location on their own website. Just as a reminder (and this applies to all documents, not just these reports): if you don't want documents indexed in Google, either don't put them on the public web where they can be found by search engines, or block them in robots.txt, or put them in a password-protected directory.
