In Google webmaster tools, under parameters in the Site Config section, Google is reporting a lot of 'redirect_to' parameters. Clicking on edit and then on show example urls confirms that googlebot is actively seeing my sites login pages.
I'm not worried that Google is actually getting into my admin panel, without being logged in that's not possible, but I don't want these pages on my link graph or as part of any metrics used to evaluate my site, they are strictly admin pages not designed for users.
This is what GWT reports...
Sample of recently crawled URLs
http://www.example.com/wp-login.php?redirect_to=
So how would I best go about removing these from Googles history and avoiding any more 'recent crawls' to them?
