Google Webmaster Central release Updates
Google Webmaster Central has released some updates: one to the API settings and one to the crawl errors feature.
Here is new things you can do with your API settings:
• Crawl Rate: You can request that Googlebot crawl your site slower or faster than it normally would (the details can be found in our Help Center article about crawl rate control). If many of your sites are hosted on the same server and you know your server's capacity, you may want to update all sites at the same time. This now a trivial task using the Webmaster Tools GData API.
• Geographic Location: If your site is targeted towards a particular geographic location but your domain doesn't reflect that (for example with a .com domain), you can provide information to help us determine where your target users are located.
• Preferred Domain: You can select which is the canonical domain to use to index your pages. For example, if you have a site like www.example.com, you can set either example.com or www.example.com as the preferred domain to use. This avoids the risk of treating both sites differently.
• Enhanced Image Search: Tools like the Google Image Labeler allow users to tag images in order to improve Image Search results. Now you can opt in or out for all your sites in a breeze using the Webmaster Tools API.
For the crawl error feature, you now get to see the URL of the inbound link that is linking to an error page.
