The ability to explore link information for any domain is here! Dive deep with this beta tool which allows you to explore links associated with any domain. Simply enter a URL and the tool will supply a list of known links pointing to the specified destination. The default setting will be to display external links pointed at the specified URL, though this can be switched to show internal links as well.
