What can Google tell about a website from Chrome or its toolbar?
-
Besides crawling with a bot, what kind of info about site construction, html, etc does Google get via users via alternate methods?
Thanks... Darcy

Danny Dover wrote a nice post about this back in 2008, but it still applies today and is a great read here: http://moz.com/blog/the-evil-side-of-google-exploring-googles-user-data-collection
The list is almost mind boggling when you add it all up... especially if you consider the different facets of Google that might not necessarily share data, but certainly could: things like Google+, Adwords, Doubleclick, Registrar Data, Server logs, mobile, Google Accounts, Gmail, Chrome, Android, and so on..
I don't want to spoil Danny's report though, it's still a great read on perspective, even after 7 years. Cheers!
