One of the great things about working at Google is that we get to take advantage of an enormous amount of computing power to do some really cool things. One idea we tried out was to let webmasters know about their potentially hackable websites. The initial effort was successful enough that we thought we would take it one step further by expanding our efforts to cover other types of web applications—for example, more content management systems (CMSs), forum/bulletin-board applications, stat-trackers, and so on.

This time, however, our goal is not just to isolate vulnerable or hackable software packages, but to also notify webmasters about newer versions of the software packages or plugins they're running on their website. For example, there might be a Drupal module or Joomla extension update available but some folks might not have upgraded. There are a few reasons a webmaster might not upgrade to the newer version and one of the reasons could be that they just don't know a new version exists. This is where we think we can help. We hope to let webmasters know about new versions of their software by sending them a message via Webmaster Tools. This way they can make an informed decision about whether or not they would like to upgrade.

This will be a great feature: If you have many websites, you can't check them frequently if there are patches for all the plugins or modules.

We're convinced that structured data makes the web better, and we've worked hard to expand Rich Snippets to more search results and collect your feedback along the way. If you have review or people/social networking content on your site, it's easier than ever to mark up your content using microformats or RDFa so that Google can better understand it to generate useful Rich Snippets. Here are a few helpful improvements on our end to enable you to mark up your content:

Testing tool. See what Google is able to extract, and preview how microformats or RDFa marked-up pages would look on Google search results. Test your URLs on the Rich Snippets Testing Tool.

Google Custom Search users can also use the Rich Snippets Testing Tool to test markup usable in their Custom Search engine.

This is a nice tool, next I like to see a tool that will replace old/wrong "snippets" much faster. If you see that your result has a bad CTR, you like to test better snippets or titles and currently it takes a lot of time until your website modifications are updated here.

Improve your site's visibility in Google search results. It's free.

Google Webmaster Tools provides you with detailed reports about your pages' visibility on Google. To get started, simply add and verify your site and you'll start to see information right away.

Another free and useful tool from Google. Worth a look at since who knows how to get you ranked higher on Google than well errr... ummm... Google!
