The Webmaster Tools team is lucky to have passionate users who provide us with a great set of feature ideas. Going forward, we’ll be launching some features under the “Labs” label so we can quickly transition from concept to production, and hear your feedback ASAP. Today we’re launching two cool features: Malware details and Fetch as Googlebot. Fetch will help users find out that some of their pages have been hacked, or why they’re not ranking for specific keywords.”]
