I've been checking one of my websites in Google WMT, and seen something new is going on.. Well, while am checking I've noticed a whole new menu showed up in the navigation links - at the bottom of the list called: LABS Which adding two new more features to Google WMT: 1- Fetch as Googlebot 2- Malware details I've quoited what it was saying at the bottom of the page itself, and you can check the screenshot your self Login to Google Webmasters Tools now instep to check your website, it might not last for long I've noticed a huge increase in my site internal links up to 300x !!! Even though, have done nothing fancy during the past few weeks.. while most of those pages seems to be missing, so i thought something is going on. BTW, I've also noticed that the internal pagerank indication of the whole website is GONE !!!!
That new features are very helpful, specially that Malware test one, that will lessen the penalties because of site malware issues.
