Improved Google Webmaster Tools
If you’re a webmaster, chances are good that you’ve tried using the link: operator in the Google search box, and found that it doesn’t return complete results. Well, you can now get a ton of really interesting and useful information about your site and how Google and Googlebot look at it. The Google Blog and Google Webmaster Central Blog report that Google has added a new Links feature to their webmaster tools, allowing you to get a more complete list of who’s linking to you. Plus, you can filter and export this data.
This is really cool. If I had more time, I could spend all day looking at this data for my sites. But who I think it’s really great for is online merchants.
