I know this is a potentially stupid question but when we refer to the sandbox effect does that apply to an entire site or is to an individual page or a combination of the two? Or to put it a different way has somebody, with a site that has different pages ranking for different keywords, ever observed one page that was targeted with a campaign being sandboxed but the other page for a different keyword being unaffected in it's rankings? I'm not talking about your best guess but real world observations of individual pages being sandboxed by Google. Obviously, I am trying to understand how Google factors in the the authority of a site down to the site's individual pages. Look forward to your comments.
