Yahoo Site Explorer (beta) goes a long way toward providing some search engine transparancy. With this tool you can see which web pages are indexed for a particular site. More significantly, you can also get a complete and accurate list inbound links to any site. The list seems to be sorted, with strongest links first. Google's "link to:www.domain.com" search has been notoriously unreliable: Google provides a sample of inbound link sources, but not a complete list. Thanks, Yahoo!, for doing something better than Google.
