Google Link Reporting changes

In order to make link data searching in Google more comprehensive Google Webmaster Central released new Link Reporting Tools that allow you to create an overview of sites that link to your your site. You can even download the overview.

In the past Google's link:command showed only a sampling of backlinks, to prevent site owners from manipulating rankings.

You still won't get all the links Google knows about, as links to any of your pages contained in Google's supplemental index won't be shown. But despite this, the amount of links reported will likely be massive compared to the "regular" link lookup command.
